Common Boiler Issues

Boiler Problems you may encounter

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.
