	RE: Recommendations in Ely (Cambs) area for Full setup checks on Nibe HP setup for House. By JamesPa, 4 weeks ago Forum Air Source Heat Pumps (ASHPs)
	If they can't don't give up. Heat pumps are, in reality, all very similar so second option is to find a heat pump engineer who isn't a nibe specialist but has sufficient understanding to carry across....
	RE: Starting Our Heat Pump Journey: 1962 build 3 bed detached house By Rob of York, 4 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@ian-s I wouldn't be too concerned about the design flow temperature. As that's only the flow temperature when it's very cold outside, for example -3C. The rest of the time, weather compensation lowe...
	RE: Recommendations in Ely (Cambs) area for Full setup checks on Nibe HP setup for House. By Lizzie, 4 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Sorry, I can't give any recommendations as we're in South-West Scotland! Our installer was initially good and helpful but his company folded and we now have to rely on a company 40 miles away (for whi...
	RE: Starting Our Heat Pump Journey: 1962 build 3 bed detached house By JamesPa, 4 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@ian-s In a sense a performance guarantee rather than a guarantee of particular parameters is what a customer needs. If I were otherwise happy with the proposal I would personally accept this as suf...
	RE: Missing flow temperature in Heat Geek proposal By JamesPa, 4 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Yes that's what would happen by turning down the lsv to restrict the flow. This is part of commissioning and called 'balancing', in this case for room temperature as opposed to for equal flow (which ...

	Using he heatgeek design flow temperature of 47°, 42° return, some of my radiators are oversized. the most extreme has a heat output of 610W in a room with a heat loss of 276W . In my spreadsheet if I...
	RE: Starting Our Heat Pump Journey: 1962 build 3 bed detached house By Ian S, 4 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Hi Thanks for all of your comments, I have been asking HG some additional questions especially around the heat pump size and the flow temperature they have advised. There response is below, it would a...
	RE: Missing flow temperature in Heat Geek proposal By JamesPa, 4 weeks ago Forum Air Source Heat Pumps (ASHPs)
	I suspect that the hex in a boiler is as susceptible to being blocked by sludge as that in a heat pump. A powerflush would be a good idea in both cases!
	RE: Missing flow temperature in Heat Geek proposal By Old_Scientist, 4 weeks ago Forum Air Source Heat Pumps (ASHPs)
	As a single point of reference, we had all 12 radiators replaced during our ECO4 install with larger K2 Stelrad types. Out of interest I costed the radiators at around £2,000 on Stelrad's website. Fee...
	RE: Grant R290 DHW Cycle Interuption By JamesPa, 4 weeks ago Forum Air Source Heat Pumps (ASHPs)
	It looks like some sort of short pre-run. The question is, do other grant owners see the same? Is there any kind of 'live' display, possibly in the installer menu, telling you what the heat p...
