Megaflo unvented mains water heater - no heat/hot water - help!

Canarygirl

Hi all

This is my first post so thank you for reading.

I have no hot water and heating at the moment. I have a Potterton boiler in my kitchen and a Megaflow unvented mains pressure water heater in the airing cupboard upstairs. They are 4 years old. A plumber has told me that the Circulating Pump (CP53) made by Circulating Pump Ltd (which is joined to the water heater) is stuck and this is causing the problem. He "unstuck" it Tuesday and the system was running again. However, today it has stopped working.

Can anyone advise me how to "unstick" the pump? He wants to charge me £150 to fit a new one and I am a single mum with a young child. If not, is a pump easy to fit?

All help is gratefully recived!

Thanks so much, Jay.

Try giving the pump a knock / kick this might unstick it but if the pump is seized / burnt out you will need to replace it, not a diy job for a novice.
Price actually isnt that bad.

This is the kind of prices you can get a pump for:

If the pump has stop valves on either side, you don't need to drain the system to change it. The rest is:

1. Unscrew it: you haven't got the bigger spanner

2. Screw on the new one. Need thread with putty or PTFE to leak proof.

3. Some wiring: Mains AC.
