Warmflow ASHP costing a fortune to run and ignored by installer

Myanthony · 2022-12-15T21:16:06Z

Hi everyone. I’ve just recently had warmflow ashp fitted and the installer has been ignoring me ever since. It is supposed to run 24/7 but turns off everyday and I assume costs more to restart. I cannot afford extortionate bills, it’s has been 3 weeks and my usage has been over 1500 kWh!! Before heat pump installed I averaged max 100 kWh per month. I am a single woman and have no idea what to do I don’t even have a user manual and as I say I’m being ignored by installer.

@myanthony, it's a horrible task trying to find something you don't know what it looks like and where it could be. Ours (as you saw in the video) was actually inside the heat pump unit so we needed to remove side panels to get it in. We then had it moved indoors for a much easier cleaning experience.

I can't see one anywhere in that internal pipework, and there won't be one under the external lagging...

@myanthony

The 'Y' strainer should be in the return pipework probably just through the wall inside your home.

@myanthony

The 'Y' strainer is not that large and could have been lagged over. If you feel along the insulation for any bumps, or if you find anything sticking out of the insulation then post a photo.

It would also be useful if you could check along both the flow and return pipework and if you find anything that is not insulated then post a close-up photo so that it can be identified.

Are you certain that any electrically operated valves are fully open?

That is a good point. Our UFH Honeywell valve died two years ago leading to cold zones. It wasn't responsible for the flow errors, but worth checking.
