Information Sheet on Replacing and Fitting a Central Heating Pump

If your conventional (ie you have a hot water cylinder) boiler keeps firing then stopping, and none of the radiators or pipes get hot, one of the reasons for this is that the pump has “gone”.
It’s possible to check if it’s “gone” with a wooden spoon, or a drum stick, or any other shortish, wooden pole-like contraption.

Find the pump, wedge the spoon end against it and put the other end in your ear. It sounds like a Bob Newhart routine but I’m serious. Can you hear a mechanical whirring noise? No sound? Then it’s probably new pump time.

Don’t put your hand over the pump to feel for vibrations. There will be vibrations, you will cause them – the windows will rattle as you scream blue murder. It will be just a tad hot!
Even if you can’t tell if it’s gone, you’ll still have to get the plumber in, your heating’s not working, remember!

If the pump has been fitted properly, it will have isolating valves fitted on either side of it. These allow it to be removed without draining the system down. If you don’t have these, make sure you get them fitted this time.
