	RE: Yes, the "zoning with ASHP" topic again... By JamesPa, 24 hours ago Forum Air Source Heat Pumps (ASHPs)
	@Judith, @ccap The control problem is not actually as simple as it might seem, even in 2025! There is a whole branch of engineering ('control theory') that deals with stabilising systems subject to e...
	RE: Renewables & Heat Pumps in the News By Judith, 1 day ago Forum Well & Truly Off The Grid
	I wasn’t surprised to read that the Telegraph believes that renewable energy was the problem for yesterday’s Iberian power cuts. Clearly it won’t have helped since it has no inherent inertia, (a techn...
	RE: Yes, the "zoning with ASHP" topic again... By Judith, 1 day ago Forum Air Source Heat Pumps (ASHPs)
	@ccap you will find that Vaillant have a mode called’expanded’ which is weather compensation plus when the house gets too hot (cooking, sun, lots of people, wood burner too) it switches the heating of...
	RE: Yes, the "zoning with ASHP" topic again... By ccap, 1 day ago Forum Air Source Heat Pumps (ASHPs)
	Mars, Thanks for your response. Load compensation sounds like the solution I'm looking for! I don't want to adjust temperatures by large amounts but it does seem to be that in 2025 it shouldn't be bey...
	RE: Yes, the "zoning with ASHP" topic again... By Mars, 1 day ago Forum Air Source Heat Pumps (ASHPs)
	@ccap, running the system mainly on weather compensation is definitely the most efficient baseline, and I agree with your instinct that it makes sense for most of the house, most of the time. However,...

	@emceed, can you please give us an update on your system and what happened with the warranty issues?
	RE: Getting the best out of a heat pump - is Homely a possible answer? By benson, 2 days ago Forum Air Source Heat Pumps (ASHPs)
	Regarding the homely data access issue (or not being able to access it without going via the back door, so to speak) I contacted Homely last year about this and asked if there were any plans to expand...
	RE: Avoid the Heat Pump Villain: Why Low-Loss Headers and Buffers Can Sabotage Your Heat Pump's Efficiency By JamesPa, 2 days ago Forum Air Source Heat Pumps (ASHPs)
	@fillib It would be very interesting indeed to determine your actual house loss by plotting ASHP heat delivered vs OAT (eg on a daily basis). I looked in the spreadsheet but couldn't find the figure...
	RE: Avoid the Heat Pump Villain: Why Low-Loss Headers and Buffers Can Sabotage Your Heat Pump's Efficiency By SUNandAIR, 2 days ago Forum Air Source Heat Pumps (ASHPs)
	This is very impressive. I would not have expected the cop to increase to the extent of your graph as the ambient readings had dropped between esp between 10c and 3c…. Great result. Further there’s an...
	RE: ASHP Ecodan L9 error - No Heating but Hot Water By ASHP-BOBBA, 2 days ago Forum Air Source Heat Pumps (ASHPs)
	@phoenix15 Sorry to hear that, we are all the way down in Kent and we only cover Kent otherwise I would send you someone to help.
	RE: ASHP Ecodan L9 error - No Heating but Hot Water By Phoenix15, 2 days ago Forum Air Source Heat Pumps (ASHPs)
	@ashp-bobba Cumbria.. we have contacted the local ones we could find. Getting them to actually turn up seems to be the problem!
	RE: ASHP Ecodan L9 error - No Heating but Hot Water By ASHP-BOBBA, 2 days ago Forum Air Source Heat Pumps (ASHPs)
	@phoenix15 Mars has a list of reliable ASHP companies, I assume this would not only be for installation but all services relating. Where in the country are you?
