Help me keep the faith with my air source heat pump installation

AdamK · 2025-03-29T13:05:20Z

i knew when setting out on this road it would be a challenge i just didnt know how much of one it would be. after having many quotes some i couldnt fathom why they were so high i thought id sorted an installer. problem is they are 72miles away so first issue was doing a remote heat loss which has been back and forth several times to get it more or less correct, but still have one room thats 2m2 smaller than what i measured. anyway the next issue was getting the 28mm primaries in before the new kitchen ceiling goes in. they sent a plumber that proceeded to bugger the job up as the wall sleeve kit hadnt been supplied to him. so sent him on his way. was promised the sleeve kit the next day and i said my plumber could fit it to save them sending an engineer. next day no kit. add to this all the mods im having to do to pipe work to maximise efficiency and im seeing why the take up is tiny in the UK. im not naming the company as they are a recommended one and have apparently done good work else where but maybe thats in there local area. i know living in Boston creates its own issues being miles from any proper trades so if someone asked me would i recommend getting a heat pump in my area id have to say no. theres just not enough skilled trades where i live.

@adamk when i had my ASHP fitted by Octopus, removing old boiler and flue into roof was included in the quote, maybe it was me being fastidious about dotting is etc, wonder if anyone else had same level of service

I would have thought that including removal of the boiler was essential to be sure of qualifying for BUS, and so no installer would risk not doing it. The flue and the DHW tank not so.

Mine removed boiler and loft tank but left the flue which penetrates a flat roof. I think that's fairly reasonable, the best time to remove the flue is when the flat roof is next resurfaced. I would have done the same.

@agentgeorge My retrofit quote was for the complete installation and commissioning; the work included removing the old vented DHW tank, draining and removing the cold water storage tank from the loft and terminating / tidying up the pipework. I did have to remind them that they had agreed to remove the old plastic cold water storage tank as though they had terminated the pipework and drained the tank, they thought that they were to leave it in situ in the loft. I pointed this out and they dutifully cut up and removed the tank and re-arranged the lagging that had covered it to add to the layer of loft insulation where the tank had been. They also removed all the old piping for the gas boiler and filled the void where the flue had been. All work was within the contract price and I imagine the scrap value helps to defray costs 😉.

I kept all the scrap, got £20 for the gas boiler, have a ton of old copper from 2 previous boiler installs, most 22mm to so nice and heavy.

They did fill the hole in the ceiling, but there was no cold tank to remove, that went with boiler 1 to boiler 2 repositioning.

Also got a good bucket of brass fittings from the old boiler strip down, and lead from the roof replaced by the new extension for the utility/machine room
