How do I know if my heating pump has failed?

Although you cannot legally repair your boiler’s circulator pump yourself, you can try to diagnose the problem. Generally, there are a few steps you can follow to figure out whether your boiler heating pump has failed.

  • Are your radiator or hot water pipes hot?
  • Can you hear the pump running?
  • Is the pump receiving an electrical supply?

If your answer is no to any of these questions, it is likely that your heating pump has failed and you should call a Gas Safe registered engineer immediately to have the problem fixed. The right engineer will have a Gas Safe ID card issued to them.
