  1. The pump is not pumping round correctly

In some instances, it might appear that your central heating pump is working and switched on; however, it is not pumping water around the system correctly. If the pump is hot, it could be an issue with the pump’s motor or the propeller. It is generally advisable to have a new pump motor fitted or replace the entire pump and body if this is the case. You can find a wide selection of pumps at Pump Sales Direct.

 

  1. The pump is working but the boiler is not lighting

Central heating pumps can be working but your heating system is not operating because the boiler won’t light. Here you should ensure that your pilot light has come on and then check that your gas supply is on. If you find the pilot light is not on, you should relight it using the boiler’s instructions. If the light does not remain lit, you are likely to need a new flame failure device.

 

  1. The pump has no power

When there is no power to a central heating pump, it is likely that a fuse has blown within the system or your heating is not requesting the pump to switch on. You should speak to a heating engineer, as there could be a loose connection somewhere within your heating system.

 

  1. The central heating pump leaks

Central heating pumps can become corroded with age, which can cause them to leak. When this occurs, your only option is to replace the whole pump. It is unlikely that you will be able to fix the leak on a long-term basis and the corrosion will only get worse. A central heating pump typically has a lifespan of between 15 and 30 years. If yours has been operating for 30 years or more, it has done exceptionally well and you will probably find a new one far more efficient.

 

  1. There is an airlock in the pump

Airlocks can often occur within a circulation pump and can be easily rectified. All you need to do is loosen the head screw using a flat head screwdriver, which will release the air that has become trapped.

 

These are some of the most common issues you will find with a central heating pump. In some instances they are easily resolved, whereas others will require more extensive repairs or replacements. If you are in any doubt about the cause of the problem, you should consult a qualified heating engineer.
