We hope it never gets that far, but in case you need a little advice when it comes to the six most common boiler troubles, we decided to put together this boiler troubleshooting guide for you.
1. Boiler produces no heat.
Possible reasons why your boiler is giving you nothing in return:
- There could be a lack of power.
- The water level is too low.
- The pilot light or electronic ignition could be malfunctioning.
- The thermostat is malfunctioning.
2. Poor heating performance.
Possible reasons why your boiler is barely working:
- Is the poor performance all of a sudden? The water level could be too low.
- Has the poor performance gradually occurred? Mineral deposits may have built up.
3. Noisy pipes.
Possible reasons why your boiler is being so noisy:
- Water may be trapped in the return lines.
- Your boiler’s circulator may be faulty.
4. Not all radiators heat.
Possible reasons why all your radiators may not be heating:
- Single units that are not hot from bottom-to-top could have air trapped in the top.
- Entire heat zones lacking heat could have air trapped in their lines.
- Entire heat zones lacking heat could have faulty zone valves or circulators.
5. Water leakage around boiler.
Possible reasons why your boiler is leaking:
- You have a faulty pipe connection.
- You have a faulty circulator pump.
- You have a faulty pressure relief valve.
6. Expansion tank has excess water and inadequate air.
Possible reasons why your tank has inadequate air and too much water:
- The pressure in your expansion tank has dropped below its efficient working range and needs to be recharged.
Some of these issues could be beyond the average homeowners ability to fix, but knowing what the problem is will take you a long way towards finding the correct resolution.
