8 Common Boiler Problems

8 Common Boiler ProblemsBoiler issues can catch you unprepared. Not only does it affect your comfort within your home, but it can also lead to costly damage and high utility bills. If you suspect boiler issues, it’s a good idea to schedule a maintenance appointment.

Common Boiler Problems

Here are some common boiler problems and what you can do about them.

1. Water leaks

Corrosion around your pipes can cause leaks to develop. A leak can also be caused by broken components such as a pressure valve or pump. Call a technician to ensure that the boiler pressure is not too high and that the boiler was installed correctly. Water leaks should be addressed right away because the leak can lead to property damage and mold.

2. No Hot Water

Low pressure, faulty valves, and even a broken thermostat can keep your boiler from heating. If your boiler doesn’t heat as expected, it could be a simple fix, or it could mean that you need a new unit. The best course of action is to schedule a maintenance call.

3. Frozen Pipe

A common issue during colder seasons is a frozen condensate pipe. The condensate pipe transports condensed moisture from your boiler to the drain. When this freezes, it can create a blockage. Insulating the line can help prevent freezing.

4. No Power

Another common boiler problem is that the boiler won’t turn on. Check your breaker box to see if any switches have been tripped. If everything looks normal, check for a blockage and ensure that the boiler pressure is normal. You can repressurize your boiler or call your HVAC company for help.

5. No Pilot Light

Under the boiler is a flame that keeps the system running. When that pilot light shuts off, it’s often due to a faulty thermocouple. The thermocouple regulates the boiler’s gas supply. However, there are other reasons your pilot light might be out. For instance, your gas may be off. In most cases, you can try relighting the pilot light according to the manufacturer’s instructions, but if you smell gas but don’t see a flame, do NOT try to relight the pilot light. Call your heating contractor or the fire department for help.

6. Strange Noises

If you hear an odd rumbling or whistling noise, then your boiler could be suffering from a build-up of mineral deposits. The minerals from the water supply accumulate over time and prevent water flow in the heat exchanger. This can increase heating bills and cause damage to the boiler, so it’s best to call your HVAC company as soon as you hear any odd noises.

7. Boiler Switches Off

Frozen pipes and low water pressure, among other things, can cause your boiler to switch itself off. The solution depends on the cause, so you should call a professional to look at your boiler.

8. Low Boiler Pressure

When there is a water leak, your boiler will lose pressure. You may notice water in and around the unit or that your boiler keeps turning itself off. Check the pressure and, if necessary, repressurize the boiler according to the instruction manual. If you suspect corrosion or a blockage, call your HVAC company.
