ASHP - how to buy
A pointer, please. I'm building new and I have opted for ASHP (I've seen nothing especially wonderful about ASHP, but it seems to deliver at a comparible cost to oil, and easier to get BC/SAP on board, but this is not the point). I'm in N Ireland and have 3 prices from installers that use their suppliers design service (Grant, Warmflow and another). None of the 3 can provide any detailed information on what their proposed system is, basically " in case the design is copied". I want to know a lot before i decide, from pipe size to zones, to controls and equipment, coz i get one shot at this, its expensive, and must work without me having to get a degree in Turning-On-The-Heat!!.
Until this moment, I assumed the supplier was the cautious one, but as I write I realise that does not stack up because having designs with their equipment out there is good.
Anyhow, has anyone else had this issue? Do I just hold a tight reign, or is there a better way to choose?
@Jimbo37 I fitted my own ASHP so cant really comment on whether that is usual, but personally I would run a mile if a company wouldnt tell me what there were intending to fit. You might try Octopus for a quote or failing that have a look at the Heatgeeks site to find a trusted installer. There are a lot of bad installers out there so be careful. You might also have a look at the openenergymonitor heat pump monitoring website and seek out high performing posters to ask who installed there system.

@bontwoody yep, I'm feeling that way too and will not buy blind. However, I hope to avoid the self install too. Thanks for the resources, I didn't know about them and will check out now
