Boiler Tips for Common Problems
  1. My boiler won’t turn on.
  2. There’s water around the base of my boiler.
  3. I have one radiator that doesn’t work.
  4. It seems my boiler has been going downhill the last year, but I’m not sure why.

Problem: My Boiler Is Not Working Do you have gas boiler problems? If your gas boiler is not heating your home and water like it should, it could be something as simple as the water level is too low or the pilot ignition has malfunctioned. View common boiler troubleshooting solutions below:

  • Does the boiler have power? The circuit breaker or fuse controllolling the boiler may be tripped or blown. Reset or replace.
  • Is the water level in the boiler too low? If your boiler has an automatic filling system, the pressure relief valve should maintain a 12-15 psi by keeping the water level at at least half full. If you do not have a pressure relief valve, manually add water to the boiler by opening up the water feed valve until boiler pressure reaches 12 psi.
  • Is your pilot light out? If so, simply relight it.
  • Is your thermostat on a heat setting? If not, make sure it is and set your desired temperature.
  • Did your gas boiler problems happen over time? If so, you could have mineral deposits in the boiler or on your heat exchanger. If this is the case, you should call a service technician to clean and flush the boiler.
  • Is water leaking around your boiler? You could have a faulty pump, pressure relief valve, or leaky pipe connection. If you see any water at all around the base of your boiler, it is best to rely on the expertise of a service technician to determine the exact problem.
  • Do you have a baseboard that isn’t heating? This could be because of excess air in heating pipes. Open the radiator bleed valve at the top of the radiator to get rid of the air. When water starts to squirt from the radiator, close the valve.
