	RE: Why are ASHP installs so expensive? By JamesPa, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	It is a politically motivated myth that our electricity prices are vastly more expensive than the EU. We are certainly amongst the more expensive (#6 out of 40), but not dissimilar to other large cou...
	RE: Why are ASHP installs so expensive? By springswood, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	I confess to becoming a little triggered by mention of dunkelflaute. It's not as worrying as it at first seems. This is explained a lot better then I could on the YouTube channel of Prof Gio here The ...
	RE: Heat Pump Books For Beginners: The Ultimate Guide to Heat Pumps, Bodge Buster, From Zero To Heat Pump Hero & Britain's Heat Pump Shitshow By Mars, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	The positive reviews keep coming in for Britain's Heat Pump Shitshow, and the latest comes from one of the biggest names in heat pumps, Graham Hendra: Masterpiece ***** Mars has written a new book abo...
	RE: Next steps on my ASHP journey: Radiators and Pipework By Old_Scientist, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	I have one of these fitted which also allows you to regulate the flow should you need finer control, although I just leave mine fully open and turn the circulation pump(s) down to achieve the desired ...
	RE: Next steps on my ASHP journey: Radiators and Pipework By Rob of York, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	First up once I have a flow meter fitted is to simply measure flow speeds and hence flow rates at the three available pump speeds with the existing system. Since it may be that there is no issue.
	RE: Next steps on my ASHP journey: Radiators and Pipework By Singlespeed, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa since going back to bed and reading again this morning, I have looked for the edit or delete options 🙁 There shouldn't be a requirement for elevated flow temperatures, as the ...
	RE: Next steps on my ASHP journey: Radiators and Pipework By JamesPa, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	That's not really the case. Average surface temperature (to first order flow temperature) determines energy transfer from rad to room. This needs to equal the room loss. DT will then be determined ...
	RE: Next steps on my ASHP journey: Radiators and Pipework By Rob of York, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@singlespeed Thanks, however, I think there is more to it than flow temperatures, which is the main factor affecting heat pump efficiency. Radiator temperature difference to room temperature is what ...
	RE: Next steps on my ASHP journey: Radiators and Pipework By Singlespeed, 3 weeks ago Forum Air Source Heat Pumps (ASHPs)
	You've spent ages deliberating over flow rates being potentially noisy, whilst running your preferred lower flow temperature. But remember that your design criteria heat requirement will only occur fo...
	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...
