@gary And if they install a single unit, what factors influence them then? Toodles.

Logically, addressing hard water issues with a water softening solution seems like common sense ie to preserve good flow rates for an ASHP system, but I’m keen to hear any views from the experts.

Moved in a few years ago, heat pump already installed. Heating bills very high and looking to optimise performance as much as possible (from browsing these forums, my system appears to show many other red flags too!)

thanks

We had our CTC ASHP fitted by our housing association contractors and it was a complete nightmare tbh there were several problems and we ended up after 2 years down the line after a load of visits and false info by contractor who basically didn’t know what they were doing reaching out to the manufacturers CTC who were much better and sorted out the system.
In the end they changed our unvented DHW cylinder it was faulty (noisy coils), a faulty incorrectly fitted ESBE valve, the TRV valves on rads were wrong and new ones fitted, the isolation switch outside was full of water and had been disconnected it needed replacement , the heating pump was set incorrectly and pretty much all of the settings on the control unit were wrong. 
The system is now working a lot better but we have no real way of knowing the scop or how economical it is, or what the flow temperature should be (never saw a heat loss survey)and also we were never shown how to work the system by the contractors. We ended claiming around £600 compensation from them for all the energy it used as it drove us into energy debt.

I have to say once we got intouch with CTC they were really good and Gogeothermal came out to resolve all the issues they were really great.

@retrorich It is very worrying that any of this should be necessary though,  having third parties involved to fit and commission heat pumps seems to place an additional barrier between the end user and common sense. When things go wrong (which of course, they never do, do they?!), the enduser finds redress has an additional layer of ‘not me guv’ in the chain to circumnavigate. Good for CTC that they put some effort into sorting it all out eventually - but… NONE OF THIS SHOULD BE NECESSARY IN THE FIRST PLACE! Come on MCS - wake up and do the job you profess to be doing! Regard, Toodles. (Rant over… for now)
