Looking for residential boiler prices ? In the US most houses contain hot water boiler systems for heating purposes. Their purpose is to keep the house warm and perfectly humid during extreme weather conditions. Not only does the central heating system save your energy and time, but also avoids the mess caused by lighting fireplaces in every single room to keep them warm There are varieties of these boiler repair specialist and boiler prices  so that you can choose according to your preferences. New boiler come in different sizes, and a correctly sized boiler system can perform its best. Sizes may vary according to the region you are residing. For colder areas to heat your home, you will need larger gas boiler to keep your house perfectly warm and cozy so boiler prices are accordingly.

How does the boiler system work?

The central heating boiler system works with heated water which circulates through pipes around your house. To simplify it, we can say the water that is used to keep the house waterfall shower warm is held in tubes at the time of the whole setup. These gas boilers systems work with the help of natural gas or oil. It is used to heat the water and the heat energy is transferred from the heated gas to the liquid water. The electric pump in system pushes the heated water, and it completes its circle by passing through different radiators to keep water heated. When the water goes through the entire house, it eventually cools down and comes back to the starting point for heating. This same process happens continuously, and the same water circulates through the house every day the fuel type is natural gas heating systems.

It is crucial to look at the various aspects of a boiler if you are planning to have one. Following are the different types of boilers.

Condensing and non-condensing boilers:

The main difference between a condensing and non-condensing boiler is its high efficiency. Annualized Fuel Utilization Efficiency (AFUE) determines the efficiency of these systems and the percentage of heat created and being transferred to the water articulate it. Boilers with efficiency between the rates of 80 to 84 are known as standard or non-condensing boilers, and these are the most economical ones. The efficiency of 85 to 90% is considered as high efficiency.

On the other hand, condensing boilers are mostly floor-mounted which are more abundant in capacity and wall mounted which are small-medium in size. The best thing about them is their efficiency which is 95% or higher. Its complex heat exchanger is the main reason behind such higher efficiency.

Water and Steam Boilers:

In water heaters, the burner heats the water to a specific temperature not more than 200F. On the other hand in steam boilers, the pool is heated to boiling point, and then the steam is pushed through pipes to make rooms warm. Water or hydronic boilers need more water than steam ones. For water boilers, the water is filled up to the top of the water tank, and for steam boilers, the water level is little lower so the generated steam can have space. In the case of efficiency, hot water boilers have been more efficient and safer than steam ones. However, the unit’s ability entirely depends on the manufacturers of water and steam boilers.

Combination boilers:

These boilers are also known as combi boiler. As its name shows that it is a combination of two features. It will not only serve the purpose of making your house cozy and comfortable but also fulfill your hot water needs like a combi boiler. Its functions work separately, the heated water circulating the house to keep it warm is separate which is known as ‘space heating’. Similarly, the hot water which runs through the taps is a separate function and is known as ‘water heating’. These boilers can save your space and performs very well as they offer high efficiency too. Be sure to check the  efficiency ratings and efficiency boilers.

Outdoor Wood-fired boilers:

These boilers serve their purpose of heating the indoors while working outdoors. There are different types of these boilers standard boilers, Catalytic outdoor boilers, and outdoor gasification boilers. However, standard outdoor boilers are less efficient and require more work. Newer versions of these boilers are more efficient than standard ones.

Floor standing and wall mounted boilers:

Traditionally, the boilers which are fueled by biodiesel, oil or wood are installed on floors due to their size and functions. These are also known as floor standing or free-standing boilers, and these boilers work with every type of fuel natural gas, oil, propane, biodiesel and wood. On the other hand, boilers working with natural gas are mostly wall-mounted. Wall mounted boilers are space saving and also more efficient regarding functionalities.

Single stage, two stage and modulating boilers:

DHL Mechanical 115 Midglen Pl SE, Calgary, AB T2X 1H6 (403) 863-8246

Separate stage boilers have sensors when the temperature lower than the specified limit then it turns on in its 100% capacity, the boiler to heat space. When the temperature rises, and the area is heated to a specified threshold, the boiler shuts down automatically. Similarly, two staged boilers operate on two capacities: either on 60% or 100%. It will help in generating more even heat throughout the house and does not create sudden heating which is quite uncomfortable. These boilers are more efficient than single staged as they operate quietly. Regarding the cost, it is worth having such boilers because it offers excellent value at a bit higher price.

Modulating boilers work on the lower settings continuously and performs specific actions when required. Some of the models can work on even 40% of the capacity and still maintains the proper heat throughout the house. Due to its higher efficiency up to 98% and performance, it cost much higher than the other two types, and it is the best option to enhance the comfortable experience. so of the older ones are oil fired boilers

Pricing of the boilers:

Now we know the varieties of water heater boilers, let’s talk about the pricing of these boilers. There are three main factors which affect the pricing size, efficiency, and performance. its good to check the energy star  rating for a new boiler as you want a good annual fuel utilization efficiency.

Size:

The price goes up with volume. The larger the size or capacity, the more expensive it would be. The ability of boiler required for the house depends upon several other factors. These factors include the insulation of the house, whether it is a single story or double story, the material used in the ceiling and how much energy efficient windows and doors are.

Type of boiler Efficiency:

  • Standard boilers are the lowest in price as they are less efficient like gas fired
  • High energy efficiency y Boilers are moderate in price as their efficiency is from 85%- 90% AFUE
  • Condensing boilers are the most expensive ones as their effectiveness is highest than others.

You can choose from less efficient boilers to condensing ones according to your requirement. These boilers can be changed according to the zone you live in. Zones 1, 2, and 3 does not require that much heating as the weather is not that much extreme in these areas. Similarly, areas under zone 4 and 5 can go for high-efficiency boiler and areas under 6, and 7 can choose from condensing boilers to make their experience of the warm and cozy house more comfortable.

Performance:

If you take a look at the US Climate Zone map you will see zone 1, and 2 are mostly hot, and zone 3 is significantly warm, so does not require that much heating when the weather is changed. Therefore the performance wise staged and modulating boilers can do the job for such areas. Similarly, zone 4 is moderate not very hot and not very cold. The temperatures started to lower from zone 5, and zone 7 is noticeably frigid which requires combi boilers for higher performance in such areas.

Extra tips before installing a boiler:

  • When choosing for a perfect boiler, you must search for the ideal contractor as well. You must not compromise the quality of the boiler for the sake of lower installation prices. Always consider three bids and the latest tax credits must be taken into consideration to finalize the best price.
  • If you are considering to replace your boiler then you must take care of the following things:
  • If you need to cover more space for heating, you will need one size larger than before
  • If your home has newer windows and is more insulated then back, you must consider buying one size smaller boiler then before as it will perform very well.
  • These are the top rated brands which provide high-quality boilers. Here, one of the most important things you should keep in mind is the performance and reliability of the system are dependent upon the quality of installation. Therefore, it is essential to hire an experienced contractor to install your boiler to save from spending extra money.

Best Time To Service Your Calgary Boiler

Why Summer Is TheBest Time For Servicing Your Residential Boiler

We tend not to give careful consideration toour warming frameworks during the hotter times of the year, however, it’s really the most advantageous time to do any support, a boiler service or moves up to more up to date, progressively proficient models.

It’s a typical error to totally overlook the boiler and boilers during the hotter months as this may prompt issues when you require the boilers most. Another motivation behind why it can be such a smart thought to settle these issues during the late spring months is that architects have a tendency to be less occupied, and can react to calls sooner.

Why should you consider the summer season for maintaining your boiler?

On the off chance that your boiler is expected to be adjusted, it is likewise great to plan this for the late spring months. Keep in mind that you should turn your boiler off a couple of hours before your architect is expected. Is summer a decent time to get a boiler benefit?

You might be a landowner or property holder that needs to frequently pay for upkeep get out charges. By putting resources into the most recent boiler innovation now, families and proprietors can spare critical measures of cash in the more drawn out term. By supplanting an 8-10-year-old boiler with another proficient boiler, you could diminish your property’s vitality utilization by a third, setting aside plentiful bucks every year on your gas charge.

Issues with Components

It’s additionally prescribed that you routinely open the thermostatic radiator valves during the hotter months. The pressing inside the radiator valve can end up stuck in the event that it is out of utilization for a really long time. It’s proposed that you don’t go out on a limb of leaving your radiators turned off for a considerable length of time at any given moment and let water from the boiler move through on month to month interims.

Late spring Maintenance

At the point when the frosty climate strikes, it influences everyone in the meantime. The whole way across the nation, boilers will start up to avoid the feared chilly and it is now that property holders will find any flaws with their warming framework.

Address any warming administration/repair design and solicit when their busiest time of the year is and they will reveal to you it’s the main indication of the icy season. To stay away from the failure of not having the capacity to get to an accessible architect, do the shrewd thing and have it seen to during the late spring.

Few things to remember

  • Switch your boiler on at any rate once every month.
  • Consider substituting your boiler for an appraised apparatus if yours is more than 10 years of age.
  • If you speculate any issues with your boiler get out a designer before the climate turns (your apparatus may even now be under guarantee).
  • Make beyond any doubt your boiler has been overhauled as of late at any rate once per year (inadequately kept up boilers are at a higher danger of carbon monoxide harming).

Necessary Cleaning

Run your boiler once per month during hotter periods. Like any machine, if your boiler is left sit out of gear, it will enable tidy and grime to gather. Such contaminants can originate from various diverse sources including consumed funnels, close-by cooking and general family unit tidy.

Since our homes are consummately fixed with twofold coated windows and entryways with protected dividers and space, it makes the ideal condition for tidy to amass. At the point when clean assembles, it can cause a blockage or obstruction with boiler parts, for example, the pump.

Set up a general update or utilize the boiler’s clock framework to make a month to month switch on.  Remember to intermittently utilize radiators enabling the thermostatic radiator valve to be opened.

Replacement issues

Being without a boiler for any number of days in winter while another one is fitted is surely not perfect. For the most part, a boiler substitution can take in the vicinity of 1 and 3 days – this can be significantly more on the off chance that you are having work done on the focal warming framework in your home.

Not having the capacity to depend on your boiler during this time can make life troublesome, and you could even risk solidified funnels if the climate is sufficiently cool. By having the work done in the late spring months, you ought to have the capacity to remain warm and not confront such a great amount of disturbance in the day to day life.

Numerous individuals wind up hurrying to have their boiler supplanted in the winter, particularly if this is on account of it has separated. By preparing and having your boiler introduced in the late spring you have room schedule-wise to look into boiler composes and brands to make sense of which one is perfect for your requirements.

In the event that you hold up to the point that your kettle separates to supplant it, you could wind up confronting a broken heater amidst winter. This could mean getting out a handyman for crisis work at a less advantageous time and notwithstanding paying significantly more! By supplanting your kettle in summer, or even simply having it overhauled, you run a far lower danger of an evaporator breakdown over the colder months.

CONCLUSION:

It is justifiable that mortgage holders and business chiefs may turn out to be less worried about the working of their boiler once the climate starts to get warm. In the event that you are fortunate to have great climate over the late spring months, you won’t need to utilize the boiler much by any stretch of the imagination, which is uplifting news since it implies you will spare cash.

Be that as it may, it may be a mix-up to totally overlook the boiler during the late spring as this could prompt issues once the icy climate returns
All of the above information clearly justifies the fact of servicing your boiler during summer.

 

High Velocity and Conventional Air Conditioning – How can you tell the Difference?

 

 

There are so many people in the world who have no clue what each of these are let alone the difference. Whether you have a science background or not, one tends to get confused when they hear the term conventional AC next to high velocity. That is exactly the reason why you must understand which is which so it could help you in your daily life. That, or so you can just sound smarter in front of your friends and family.

The difference between the two is based on three things:

Circulation – Difference in how they work:

If you remember science class correctly, there are different ways in which air rises and falls. This forms the basis for the circulation in different spaces. A conventional AC system depends on the method of diffusion which is the spontaneous spreading of air particles. The diffusion helps spread cool air particles that enter the room through a vent. Laws of thermodynamics apply here in which hot air rises while cold air falls. This forms the conventional currents. The circulation of the air depends on where you place the vents.

High velocity Air Conditioning systems depend on the effects of aspiration. This is when air particles enter a space in such speed that they create air currents. These air currents then move on to assist in circulating the cooled air around the room. The aspiration method is best known for its use in homes near the sea or where the area is high in humidity.

The Kind of Ducting Used:

Ducts help to take the cool air all around a building or home. The kind of ducts that are installed depend on the kind of building it is as well as the need. Conventional AC systems require strong metal ducts. These metal ducts are 6” in diameter and have two branches that help with supply and intake of cool air. Because of the diameter of the ducts, the architect has to make sure there is enough space for them to be installed throughout the building.

High velocity AC systems however use smaller ducts that are made up of insulated aluminum tubes. These tubes are three times lesser the size of the other and can fit into any tight spot. They are usually lined inside the walls and are chosen for older homes. A much more commercial use depends on the size of the area they are to be installed in.

What each Costs?

Although the high velocity tubes are smaller in size, they are higher in price than the conventional AC ducts. This is due to the kind of material they use and the per meter cost of it. The overall cost also depends on the kind of structure you want them to be retrofitted in. The good thing about high velocity tubes is that they require lesser construction cost therefore both are at the same page. It all depends on you and your need in the end.

 

Is Under-Floor Radiant Heating More Efficient Than Conventional Systems?

Boiler Service Calgary

DHL Mechanical Boiler repair and HVAC Services Calgary

Floor radiant heating system is considered to be energy efficient for its design and installation method. It can provide consistent heat to the rooms due to the continuous circulation of hot water. It works on a direct contact system with the objects and people in the room without heating the air. Hence the heat retention period is longer. Proper space insulation can result in higher heating during coldest seasons with energy conservation.

Under-Floor Radiant Heating System – Design and Construction

Reduced Loss: heat loss can happen at the furnace, along with the pipes, and inside the space being heated. The net loss of heat for a radiant system is significantly low compared to the conventional systems. We can analyze the probable reasons in the next sections.

Low Temperature: Radiant heating systems work at low temperature (between 20-degrees and 29-degrees) to generate maximum volume of heat. Hence, the energy consumption is always optimized.  There is no need to overheat the water at the furnace. You can set the maximum /minimum temperature value for the auto of/ on the furnace. The system works efficiently without your intervention.

Heat carrier: Hydronic radiant systems use water for carrying the heat from the source to the emission points. Water can heat at a low temperature. It can also retain the heat for an extended time, unlike other fluids. Percentage of loss is much lower compared to the others. It can also carry the heat over long distances. Radiation of heat from at the emission points is even and consistent.

It is possible to mix the proper kind of additives to water for increasing the heat carrying capacity. The contractor can also enhance the efficiency by adding thermostats and other elements at the emitting points and the pipelines. It can further enhance the heat carrying and retention capacity.

Insulation Strength:  Strength of insulation panels, piping layers, and related components is much higher for radiant systems. For example, the PVC layer over the pipes can prevent the loss of heat during the flow from source to the emitting points. The insulation panels at the emission points ensure directing the heat through limited vents. Hence, the room heating happens efficiently and effectively.

Heating-Panels: Heating panels at the emission points play an important role in the optimization of temperature control. The rate of emission can be controlled with the help of manual or automated switch systems. Once the room temperature reaches the maximum value, the emission and heating systems get disconnected until the minimum temperature is reached. The system helps in saving energy and fuel consumption.

Under-Floor Radiant Heating System – How it Works  

Heating mechanism: Under-floor radiant heating system works similar to the sun’s radiation heating the earth. You might have experienced cool blowing breeze even when the sun is emitting maximum heat. Your body and the objects around you get heated, but not the air. The radiant heating system works on similar principles.

Heat Retention; The radiant heat increases the temperature of the human body and the objects within the space. Air remains at room temperature. Hence, there is no loss of heat due to air circulation. Your body and the objects in your room can absorb and retain heat for a long time. For example, you can observe the changes in heat retention after installing sofas, furniture and fixture, carpets, and other heat retention objects in your living space. Even the woolen curtains and upholstery in the room can absorb and retain heat.

Insulation Effects: Having an optimized insulation system in the living space can increase the heating efficiency and retention time significantly. The time interval between two subsequent heating cycles can also increase substantially. Hence, you can expect to save more on energy compared to the conventional systems.

Circulation Mechanism: Water temperature will continue to remain at optimum levels once it passes through the pipes at the emission points and returns to the source. For example, the water temperature of 29-degrees at the emission point may retain the heat at 15-17degrees. So, the fuel required to heat it to 30-degrees or higher is lesser in radiant systems.

Conventional-Systems: Conventional systems don’t have any circulation and return mechanism. Moreover, they heat the air within your living space. The temperature of the air at the heater core could be the maximum. But it loses heat as the air circulates to the roof and returns. Then the heat has to work consistently to keep the temperature at the optimum levels.

No-Sweating: Radiant heating systems don’t make you sweat while being inside the room. It is because room air remains at optimum levels. So, the probability of getting affected by skin allergens is very low compared to the conventional systems.

Heating effects will be at the optimum level as long as the heater is on. Once it is off, the heating effects reduce considerably within a short span of time. Heating frequency and volume have to increase with the room size. Larger rooms require higher capacity heaters.

Radiant Heating: The above-listed problems of conventional heating are eliminated or reduced in the radiant heating system. It can work consistently for any size of room since there is no heating of air.

Health Factors: Radiant heating systems can eliminate the pathogens and allergens in the air since the heat comes into direct contact with such elements. It can also clean the air from finest dust and dirt particles by precipitation. The efficiency of conventional heaters in this aspect is much lower compared to the radiant systems.

Summary

Efficiency: Radiant heating system with Hydronic technology has been practically proved to be more efficient in terms of fuel consumption, effective heating, heat absorption, and retention. It is also economical due to the low maintenance costs. The parts and components are more durable due to the lowest probability of breakdown.

Aesthetics: The best part is about the aesthetics and interior designs of your rooms. Under-floor radiant systems remain hidden from external surfaces. So they don’t spoil the beauty of your room and home interiors unlike the conventional systems, which can occupy a considerable volume of space in your rooms.

5 things you can do to service your own boiler system

Boiler Service

Regular monitoring and Boiler maintenance can prevent most of the breakdown problems to a considerable extent. Boiler system can become susceptible to leaks, pressure and temperature variation, rusting, parts malfunction, and internal contamination.

  1. Cleaning: Cleaning your boiler keeps it free from contamination and rusting. You can use the cleaning brush to remove dirt, carbon and other deposits from the tubes and heater base. Focus on venting points, joints, flues, filters, and circulators. Use non corrosive liquids to remove the rust deposits.
  2. Lubrication: Manufacturer recommended lubricants for fan, pump, piping joints, screws and bolts, and motor can prevent rusting and friction. It keeps the parts running smoothly without overheating. Lubrication can also improve performance efficiency and prevent loss of fuel. You can identify the parts to be lubricated from the boiler user manual.
  3. Leak-Sealing: Check your boiler for leaking points. They may be found near the valves, joints, welded points, and piping. In the first step, you have to identify the leaking points. Run the boiler and turn on the outlet. You can identify the external leaking points on visual inspection. Use the sealant. If it is powder, you need to mix with correct ratio (as indicated on product label) with water and make a thick paste. If it is a spray, you can use it according to instructions. Shutdown the boiler and turn off outlet. Wait for 10 to 15 minutes to ensure no water flow. Apply the sealant and let it dry fully. Use only heat resistant sealants. If you suspect any internal leaks near the sensitive points, you have to call the boiler repair professional.
  4. Flush-Clean: Shutdown the radiant heating systems and let it cool to room temperature. Open the water inlet points. Drain the water from the vents, valves, and radiators. Once water is drained off completely, you can close it. Connect the power-flushing device to the piping according to the manufacturer instructions. The device itself should get water supply from an external source. Connect it to the water inlet and add the flushing liquid to the container. Turn on the power flush device and let it run for the time specified by the boiler manufacturer. Then you can drain the water and reconnect the pipes.
  5. Fuel-Supply Checking: Check the fuel storage and supply lines to the boiler. Clean and lubricate the joints. Check the pressure valves. If you find any leaks or cracks on the supply pipes, call a professional boiler expert repairer and get the defects fixed.

Reasons owners switch to radiant heating

Switch to Radiant Heating

Radiant heating is one of the most recommended methods of keeping your home warm during cold seasons. The four main reasons homeowners switch to radiant heating are flexibility, efficiency, feasibility, and quality.

  • Flexibility: You can install the radiant heating system in the smallest and largest rooms in your home. It is easy to install over the existing floor. You can cover it with one more layer of tiles or boards from wall to wall. There is no need to install external radiators or other heating devices. You can choose the best interior design for the rooms without having to worry about disturbances from the radiant heating system.
  • Efficiency: Radiant heating system is efficient, since it doesn’t heat the air in the room. The electromagnetic radiation generated by the system transfers the heat directly onto the objects and persons in the room. Hence, the probability of heat loss is near to zero. You can customize the panel layout, switching system, and the level of heating for every room individually. The system uses the energy for selective heating. It improves energy efficiency and eliminates waste.
  • Feasibility: The radiant heating system is technically and financially more feasible compared to the other forms. There is no need to install external heating devices. The radiant heating pipes ad panels are relatively cost effective compared too the o of heating. The entire infrastructure is easy to install and configure. When you use the Hydronic system, it increases the safety parameters. The investment you make on the system gets recovered within a few months of installation.
  • Quality: Quality of air within the radiant heated space is the best and the most hygienic. The radiations can eliminate humidity, kill the molds and bacteria, and keep the air fee from contaminants in all the possible forms.

Best Practices for Radiant Heating and Cooling

Best practices for radiant heating and cooling start from analysis and system design. Calculation of space volume, assessment of external factors (average-maximum-minimum room temperature, condensation, existing ventilation, required insulation, etc), occupancy, required heating/cooling level, and related factors will be helpful. Proximity to heat source (Ex: Boiler) can determine the type of piping to be installed.

  • Design: Radiant heating design consists of two parts. First part consists of boiler installation location and piping layout. The second part involves the installation of heating panels within the individual rooms and connectivity to the operating controls. Piping material, distance, vertical height, water pressure, and external insulation for pipes can determine consistency in supply water temperature. Condensing boilers can work at an efficiency of more than 90% since they utilize flue gas to heat water. Parallel piping to individual rooms can improve heating efficiency. Utilization of return water temperature will also help improve efficiency.
  • Material: PEX tubes are mostly recommended for radiant heating systems. The material can retain heating and cooling factors from the point of heating/cooling to the points of distribution within every room. PEX is also highly flexible and strong. It can endure the stress factors of mechanical coupling, joints, fittings, looping, and other stress factors. Diameter of tubes within the panels, supply and return paths determine the consistency of flow rate, pressure, and heat retention. It is easy to form multiple looping patterns in every room, depending on the heating requirements. The material for external pipes can be PVC coated pipes which can withstand the flowing water temperature and prevent loss during transmission from source to the target points. Under-slab and edge insulation materials made of high grade foam can help preserve the heat without loss.
  • Panel: Panel dimension depends on the space volume (to be heated or cooled) and available surface area (floor, wall or ceiling).

Radiant Heating – Why Switch?

Radiant heating is the safest and the most “silent” form of keeping your home warm, hygienic, and refreshing through cold seasons. You can install the system beneath almost all types of flooring. It doesn’t heat the air in your living space. So, you don’t sweat or experience difficulty in breathing. Time required for heating for a given volume of space is the least compared to other modes. Proper insulation can ensure longest heat retention time. So, you can save on energy by its smart utilization.

  • Health Benefits: Radiant heating can eliminate most of the airborne bacteria and infection causing elements. It condenses the floating humidity and removes it from air. So, the probability of mold and mildew deposits and growth on the floor, walls and ceiling. Your living space remains free from dust and allergens.
  • Optimum Heating: You can control the required heating level in every room, independent of the others. You can also turn off heating wherever it is not required. Installation of sensors at the heating source can determine the changes heating requirement by detecting the temperature of return water. So, the fuel supply volume and the heating level also get customized. There is no loss of energy. You can change the source of heating based on your specific requirement (solar, Hydronic, etc).
  • Safe Heating: With radiant heating, you don’t need any external devices like the radiator, electrical installations, etc. Hence, it is the safest method of heating for homes with children and elderly family members. It is also the most “silent” system since there is absolutely no noise of radiators, flowing water, and vibrating air from forced air systems.
  • Saves Money: The average monthly expenses on home heating bills reduce considerably. You can also utilize the heating source for supplying hot water for your bathroom, kitchen, garage and other points of requirements.

Common Boiler Issues

 Boiler Problems you may encounter

boilers in calgary

Most of the calgary boiler issues arise due to the aging of the system, unless the brand you have installed has some internal design and construction problems. The exterior environment where you have installed the boiler, the frequency of preventive maintenance, and the parts replacements can increase the durability of the system or make it prone to frequent issues.

The issues can be minor, major, critical or chronic. You can rectify many of the minor issues with the DIY approach. The other categories require the experienced boiler repair specialist. It is due to the complexity of the problem, difficulty of detection, and the lengthy procedures of repair and part replacements.

Uneven or No Heating

No boiler loses the heating capacity abruptly unless the burner or the heat exchanger breaks down completely. Generally, you can experience a drop in the heating temperature. The rate of drop depends on the nature and the intensity of the defect developed within the internal parts.

Burner Blocks

The gas boiler burner blocks out due to the deposition of the soot. It may happen when the burner is left without cleaning or the burner material has a tendency to accumulate carbon. You can open the metal housing screws from the burner chamber. The first step is to clean the chamber itself. It is better to turn off the fuel supply before.

You can use a soft bristled brush to remove the soot deposition over the burner.  Then make use of the soot blower to clean the internals of the burner.

Heat Exchanger Blocks

The heat exchanger is one part which gets exposed directly to the flowing water. Hard water and excess of calcium in the water can result in scale deposits. They can reduce the heating rate and the temperature.

You can clean the exchanger using the hard bristled brush after opening the external chamber. If you observe any leaks on the exchanger; there is a probable crack or damage. In such cases you have to call the boiler repair specialist to fix the defect or replace the exchanger.

The uneven heating can develop into no heating condition when the system is left without repairs for a long time. If there is an abrupt drop in heating, or there is no heating at all, you can inspect the outflow pipes, burner, exchanger, and the temperature valves for any defects. Call the boiler repair expert to fix the problem.

Leaking Boiler

Water leaks happen within the boiler due to cracked pipes, broken valves, loose screws, corrosion, or the worn out parts. Leaks can also occur when there is an excess pressure due to the breakdown of the control valve.

Pressure Valve Defect

The accumulation of the sediment around the internal parts of the valve causes excess of pressure. Over a period of time, the valve screws may become loose and leak. In such cases the safety of the system will be at risk. It is better not to fix the issues using the DIY methods and call the boiler repair expert.

Corroded Parts

The corroded parts like the pipes, joints, screws, and the other interior parts can also lead to leaks. The volume of leaking could be too trivial to observe in the initial stages. It is only when the problem becomes critical, you can observe the issues. So, it is better to visually inspect the parts regularly and take the preventive measures.

When you open the exterior cabinet and view the boiler’s interiors, it is possible to view only the corrosion on the pipe and part exteriors. But it is not possible to view the internal corrosions. N In such cases, you have to call the boiler repair expert.

Defective Pump

The defective pumps in the boiler can result in the internal leaking. The loss of pressure control can often result in explosive conditions. Check the bleed screw, outline nut, housing walls (for cracks), and the other parts of the pump exterior. If you are able to see any cracks, or defects, call the boiler repair expert. He will be able to repair the pump, replace the parts, or replace the entire pump.

 

Noisy Boiler

The boiler becomes noisy when it gets older. The average lifespan of an excellent boiler will be not more than 20 to 25 years. Though the manufacturers may claim much longer durability, practical experience of the homeowners shows otherwise.

Your first task when the boiler becomes noisy is to check its age. If it’s within the “efficient” period, you can check the internal parts of the boiler.

Heat Exchanger

The accumulation of the hardening elements on the exchanger can cause the boiler to make noises. The solution is to remove the deposits. You can do it with the help of a brush and the cleaning liquid recommended by the OEM.

Loose Screws

The screws within the water feeder, extension pipe, drain valve, shutoff valve, assembly parts, and the joints can result in noise. Check if it is possible to tighten the screws and rectify the issues. For this, you will need the right sized OEM toolkit. Refer to the boiler manual and check the tool size and specifications required.

In many cases the tightening of the screws may not fix the issues. Then you have to replace the screws. Unless you are familiar with the part design and the safety factors, it is better to call the boiler repair expert to fix them.

Varying Water Pressure

The variable water pressure from the outlet can cause drop in the flow of water though the pipes into the radiant panels. It results in low heating experience. The common causes could be a defect in the circulator pump, relief valve, flow control valve; water feed valve, or even the expansion tank.

In most of the cases it is not possible to identify the exact cause of the pressure variation problem, unless you are an expert in the boiler design and construction. So, it is better to call the boiler expert and get the diagnosis and repair done by him. It helps you save on time and keep the boiler and your home safe.

 

Why Choose Radiant Heating?

Why Choose Radiant Heating in Calgary

Hydronic System

Radiant heating system is the most efficient mechanism that works on the principles of the Hydronic design and construction. The quality parameters are reliability, flexibility, scalability, and uniform distribution of heat to all the rooms in your home.

Heat Source

The design consists of a heat source boiler uses the natural propane gas or electricity to heat the water in the boiler. It can work at temperatures ranging from 800F to 2000F. The ASTM standard condensing boilers work at an efficiency of 90% and above. They have the capacity for heating the water to the required levels, depending on the external climatic conditions.

Piping

The optimized piping layout is designed to match exactly with the construction plan of your building. The highly insulated pipes can carry the hot water from the source to the individual radiant panels in every room. You can control the ambient temperature level in each room, which is independent of the others. The insulation ensures zero loss of heat during the flow through the piping channels.

How it Works

The radiant heating panel consists of a copper pipe-work, aluminum planks and a cross-brace, and the foil insulation that is installed on the cross-brace. The incoming hot water passes though the copper pipes and heats the panels. The radiant energy is transmitted into the room in the electromagnetic wave range. The waves don’t heat the air molecules in the room directly. Instead, they strike the living and non-living objects within the room to create warmth. The heated object can retain the temperature for a relatively longer period compared to the air molecules which lose heat due to circulation.

Energy Conservation

As the objects lose the heat due to emission and the temperature drops below the minimum level (as you specify in the controller), the hot water generates the waves to heat the objects to the ambient temperature. The system remains idle during the time between ambient value and the minimum value of the temperature in the room. This system enhances the energy efficiency of the radiant heating panels considerably.

Proper insulation of the room can reduce the heat loss by more than 90%. A professional contractor can insulate the heat escaping points with the synthetic materials.

Heating Efficiency

The panel designer considers the radiant floor area through which the piping is installed. It should preferably cover the living room, drawing room, bedroom, kitchen, and the bathroom. The presence of large size objects like the bed, furniture and fixture on the floor can enhance the heat retention and re-emission during the heating cycle. Concrete, metal, wool, synthetic fibers, polyester, nylon, viscose, leather, foam, PVC, and acrylic materials have the maximum radiation absorbing and retaining capacity. By having objects made of these materials in the room, you can enhance the heating efficiency of the system by multiple times.

Professional radiant system experts can plan the efficient installation in each room depending on the heating requirement. They typically avoid the areas under the wooden furniture since it is bad conductor. Hence the net floor area will cover open surfaces.

The energy coefficient for heating the panels to the ambient temperature requires the smooth flow of the hot water at specific rate per minute. The selection of the right tubes on the panels can enhance the transfer rate even when the water temperature is within the 1000F to the 1500F range.

Flooring Types

The radiant heating system can support a vast range of flooring types including the concrete, PVC tiles, asphalt, granite, and marble. The layout of the panels can happen before the installation of the flooring in cases of new house constructions. If the rooms have an existing floor, there is practically no need to remove it unless you are specific about laying the panels beneath the surface.

The radiant heating contractors can layout the panels on top of the existing floor and cover it with an additional layer of the tiles in a customized manner. It is easier for them to maintain the panels and conduct any repair works by removing the top layer of the tiles. The edgings for the tiles provide the required structural stability. The materials used for the tiles can ensure the foot traffic and light to medium weight objects like the furniture and fixtures.

Flooring Design

The installation of the radiant panels won’t affect the design or the patterns you wish to have on the floor. In fact the radiation can pass efficiently through the tiling and the carpeting layers without any loss of energy.

Wood Floors

If the existing floor in your home is made of concrete and you would like to have a wooden floor on top, it won’t affect the efficiency of the radiant heating system in any way. In fact, the tubing system and the panel can stay above the concrete layer with laminated wooden flooring on top of the panels. They can conduct the radiant heat in an efficient manner without causing any loss of heat during the transmission.

Even if the floor is made from hardwood, it is possible to install an efficient radiant heating system. Here, you need to follow certain quality guidelines for the plywood slab installation which increases the porous nature of the floor and allow maximum thermal radiation to pass through. However, the maximum temperature of the heating could be restricted to less than 900F for the hardwood floors.

Carpet Flooring

Installation of woolen and synthetic carpets above the radiant panels and the tiles can in fact increase the heating efficiency by multiple times. It is due to the heat conducting capacity of the materials. The contractor can install the heat conducting materials like the high quality rubber pads beneath the carpet to ensure no damages to the carpet resins due to the direct heating effect. The combination of the two materials can retain the heat over extended time and transmit it evenly within the room. 3

Low Maintenance

Radiant heating system has the lowest maintenance costs and the simplest procedures. Regular cleaning and vacuuming can keep the dirt, dust, and the damaging elements away from the floors. The professional radiant heating contractors can perform the maintenance works related to the heating sources, piping, controllers and the heating panels.

 

How to Find a Good HVAC Contractor

HVAC contractor licensing is the first criterion for the selection. Class A contractors have the state permit for the installation, repair, and maintenance of the HVAC systems. Class B contractors have the limitation in the handling of cooling, ventilation and the heating systems. The licensing criteria and the examination methods may vary in the various states. But the certification shall result in the granting of the License. Make sure your contractor has obtained it from the state government authority.

The second criterion is the liability insurance for the property damages and /or personal injuries occurred during the installation, repair and the maintenance procedures. As a homeowner, you will be responsible for paying the part deductibles which will be mentioned in the quote. The two legal criteria enable the HVAC contractor to work on your projects without any hassles. While searching, you need to ensure the fulfillment of the two criteria by the HVAC contractor.

Technical Criteria

Conformance to the HVAC duct standards, NFPA, OSHA, ANSI, ASTM, and the state energy and mechanical codes are the key technical criteria for the contractor. The staffs working for the contractor should be trained and certified for all the above standards from the state authorized training and certification centers. You can get to know about the details from the company profile in their website. If the contracting company is located in your local region, it is possible to interact with the directly and get the details. You can also read the online reviews about the contractor to know the details.

Client Testimonials

Read the online client testimonials on the unbiased social media to learn about their experience with the professional service provider (PSP). If you search for installation, repair, or maintenance, it is better to read the related testimonials to evaluate the PSP accurately. But they may not give you the complete description about the contractor from the practical perspective every time. So, you need to go one step ahead and contact the HVAC contractor in his office.

Personal Interaction

During the personal interaction you can check the licensing, insurance, certification, and the quality standards of the company and the workforce. It is possible to assess their experience and expertise by asking a few simple queries.

NFPA-96 Fire Protection

The standard is meant for the ventilation control and the fire protection.  It describes the fire-proof installation and configuration procedures of the heating, cooling, ventilation and the air conditioning systems. The contractor should have the knowledge about the fire rated floor ceiling assembly, exhaust hood, weather protected opening, access panels, and the exhaust and the discharge systems. Installation of fire-actuated dampers, airstream detectors, inline fans, and the extinguishing equipment should be done according to the NFPA standards. If the contractor can perform these activities, before the HVAC installation, you can depend on the service quality and safety standards of the contractor. Certification from the NFPA is an important criterion which can increase the trust factors of the contractor.

Energy Rating

Every state in the USA has its unique energy rating system for the HVAC systems. The goal is to utilize the available resources for generating the optimum energy for the heating and cooling for the entire home. The contractor shall take all the required measures to prevent the loss of energy by recycling the exhaust gasses, excess heat, and the other renewable sources to make the system more fuel efficient.  At the same time, he shall take the measures to prevent the exhaust of harmful chemicals, gasses and the other form of emissions to preserve the EPA green standards. You can check the energy rating and green certificates given by the state energy department and the federal EPA. If the contractor has the two certifications, you can consider him for your HVAC projects without any hassles.

HVAC Experience

The contractor and his team should have the relevant experience in the installation, configuration, repair and maintenance of the HVAC systems for multiple types of homes and apartments. Familiarity with the ASTM-E2690, E2231, C411, and the ANSI/UL standards for the fuel storage and supply, boiler/heater, heat exchange system, dehumidifier, Hydronic systems; supply and return pipes, central cooling and heating systems, and the radiant heating systems is critical and important.

Customization Expertise

The experienced HVAC contractor should also have the expertise for customizing the system according to the specific design and architecture of your home. If the apartment has a basement, the installation of the fuel storage, boiler/heater, cooler, and the duct base can be done in there. Otherwise, the PSP should have the expertise to design the entire system in an energy efficient manner. You can know about his abilities by contacting the existing customers. You can ask for the client referrals from the contractor company and speak to them before taking a decision. Make sure you have covered all the technical aspects and the costing. You can request them for a personal visit to their apartment and experience the efficiency of the output firsthand. Ask them about the helpdesk and emergency services provided by the PSP.

Scalability Factors

The HVAC contractor should be able to upscale and downsize the installation and the connections according to your changing requirements in the future. He should be able to upgrade the existing heating and cooling systems to match with the increasing demand by using the most cost competitive methods and quality materials.

Quote Comparison

An expert HVAC contractor will submit the detailed quote for the installation, repair, and maintenance only after inspecting the installation site/ installed systems. He may give you the referrals for the material and device supplies from the OEM. He shall specify the installation, and labor guarantee according to the State’s HVAC regulations. The device and equipment warranty will be directly from the manufacturer which will be executed by the contractor.

Get the detailed quote from him and compare it with the similar quotes from the other PSPs in your region. Prepare a spreadsheet table to list out the technical, functional, and costing factors for every product, installation, and the related labor. Finally you can take a decision on the best HVAC contractor.
