	RE: Hitachi Yutaki SCombi Heat Pump - Thermal Off's By Heatgeek, 1 week ago Forum Air Source Heat Pumps (ASHPs)
	@trebor12345 The Auto function is supposed to adapt automatically and select the right curve in constant pressure mode. By default the pump is set to middle curve and it adapts from there. See descri...
	RE: The Rise and Fall of Europe’s Most Generous Green Subsidy By Dwynwen, 1 week ago Forum Government Schemes, Regulations, Planning & Organisations
	What indeed? Not visited forums for some time, been in hibernation. Have survived the winter without ASHP. Someone was wearing rose tinted glasses when writing the above article about UK superiority h...

	Thank you this is very helpful. There is a lot to take in. I have the heating on today and have been doing videos of the Live View. The funny thing I attempted the flow calculations for the floor th...
	RE: In the middle of an ASHP installation - a few questions (and issues) By benson, 1 week ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa they didn't provide any contract, or design proposals. I had to ask what the design temp was and scop, and they just replied to the email. The only thing they did provide which was vaguely ap...

	@trebor12345 Your house is remarkably similar to mine, layout included. I have 185 sqms with 4 beds and 2 baths, same size lounge with exactly the same open plan kitchen with island and 12 loops of U...
	RE: In the middle of an ASHP installation - a few questions (and issues) By Transparent, 1 week ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa - how is that the Vaillant data-logging is showing a COP below 1.0 on occasions? Separately... Do any of these manufacturer's data-logs show when the ASHP was operating in defrosting mode? ...
	RE: In the middle of an ASHP installation - a few questions (and issues) By JamesPa, 1 week ago Forum Air Source Heat Pumps (ASHPs)
	OK that rules this one out. Good! Hmm. Fundamentally of course this is down to emitter size/house loss. I'm getting the feeling from your text that they may not have changed many emitters and you ...

	@allyfish thanks for the feedback and glad it was fun! 85% is respectable.
	RE: In the middle of an ASHP installation - a few questions (and issues) By benson, 1 week ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa yes. The installers tried to limit the max flow temps to 45, I guess to try and convince us that was the design temp but as it happened we had sustained periods of minus 2 and the house would...

	RE: In the middle of an ASHP installation - a few questions (and issues) By Judith, 1 week ago Forum Air Source Heat Pumps (ASHPs)
	@benson you asked above about the Jan comparison with other months. We have a COP of 4.0 for January and 4.7 for the October to March 6 months. This is on a 7kW Vaillant using the app figures which ma...
	RE: The Great British Heat Pump Quiz By AllyFish, 1 week ago Forum Air Source Heat Pumps (ASHPs)
	That was fun, thank you @editor. 85%, which is just as well after 35years in the HVAC industry. Some careless answers on my part, and maybe a couple of ambiguous questions. Some howlers in there as we...
