	RE: Grant 13kW Aerona3 - issues getting zones to temp By Crimson, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Just to be clear this won’t be a Grant LLH/combo volumiser. This will be a 4 port 80L max buffer/LLH. Due to space limitations. They've made no mention of flow setters etc.way back in this thread ther...
	RE: Master & Slave Zones/Setback By JamesPa, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Many, perhaps most, heat pumps run their water pumps occasionally (sometimes every 24 hrs or once per week) to prevent this. With it being such a mild day and with sun your consumption shoul...
	RE: My experience with 3 heat pump surveys: Heat Geek, British Gas & Octopus By JamesPa, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Firstly I agree with @grahamf above, very sensible comments IMHO. There is never any harm in radiators being too big, you can just drop the flow temperature. Its better if they are in proportion thou...
	RE: Master & Slave Zones/Setback By bretix, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa I'm not entirely sure TBF. I'll have a proper look at the weekend. As the settings are the same I'm assuming it's Master & Slave. The set up has previously changed when being serviced but...
	RE: My experience with 3 heat pump surveys: Heat Geek, British Gas & Octopus By GrahamF, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@jords it sounds as though you have been having a frustrating time. I had some similar experiences. Here are a few pointers: All installers have strengths and weaknesses. The most important aspect...
	RE: My experience with 3 heat pump surveys: Heat Geek, British Gas & Octopus By downfield, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@grahamf EPCI subcontracted the installation work out so maybe I got a different team. Anyway there were 4 of them and they worked hard over 4 days to complete the work. I was clear where I wanted e...
	RE: My experience with 3 heat pump surveys: Heat Geek, British Gas & Octopus By GrahamF, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@downfield it is curious that you are reporting quite positively about EPC Improvements. @drei has been alleging serious problems with their installation in his home. It appears to be the same compa...
	RE: Grant 13kW Aerona3 - issues getting zones to temp By AllyFish, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa the point is it allows variable secondary flow rates lower than the primary. In some circumstances that requires hydraulic separation where the primary circulator is a constant volume/head pu...
	RE: My experience with 3 heat pump surveys: Heat Geek, British Gas & Octopus By jords, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa that’s an interesting way to look at it. Given my gas usage the heat loss would be around 4-5kW. But we tend to run our house on the cooler side and like I said some rooms like the kitchen ar...
	RE: PV Panels on roof in Conservation Area By colinc, 2 weeks ago Forum Solar Photovoltaic (PV)
	Update: .... Council said, "Yes", to installing PV & ASHP, with a few Conservation Area (CA) caveats: basically don't put PV on walls facing a highway; and ASHP max volume is 0.3 m3, basically s...
	RE: My experience with 3 heat pump surveys: Heat Geek, British Gas & Octopus By JamesPa, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	I had a fairly similar experience with installers just over 3 years ago. For various reasons, mostly to do with planning, the project was delayed for 2years (heat pump was finally installed Nov 2024)...
	RE: Mixergy Tank Failure By bontwoody, 2 weeks ago Forum Domestic Hot Water & Cylinders
	@old_scientist Well it does seem pretty evident that it wouldnt work with it closed 🙂 but its odd OEM was showing flow, so lets see!
