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