Your boiler is the center of your home’s heating system. A boiler problem is a major inconvenience, especially during winters in central Illinois. Here are five of the most common problems you may encounter.

1. Boiler Automatically Shuts Off

There are many possible reasons for your boiler to automatically turn off. They include:

  • Thermostat problems
  • A frozen condensate pipe
  • Low water pressure
  • Air in the system

Since these can be complicated to diagnose, have a technician inspect your system to determine what’s causing the problem.

2. Excessive Noise When Operating

Excessive noise, or “kettling,” is often caused by limescale that’s building up inside the heat exchanger. You may hear a gurgling, rumbling, or whistling sound that resembles a boiling kettle. A technician can flush your pipes to remove scale and trapped air from your boiler.

3. Radiators Not Heating

If your radiator is cold on top but hot on the bottom, you could have an issue with your pump or a faulty zone valve. You may also have a buildup of air in your boiler. Try bleeding your radiators, which will remove any air trapped inside your system. If bleeding the radiator doesn’t resolve the problem, it might require a power flush to clean out the pipes.

4. Leaks

A dripping or leaking boiler has several possible causes. Your system may have a loose connection or broken parts. The circulator or the pressure relief valve may need replacing. A leaking boiler will need to be repaired by a qualified technician.

5. Boiler Loses Pressure

If you have a pressurized heating system, you may find the boiler often loses pressure. This may be caused by a problem with the system’s expansion vessel. Loss of pressure is also a potential sign of a water leak. If your boiler is losing pressure, you’ll need help from a technician to resolve the problem.
