	RE: Octopus Cosy Heat Pump Owners & Discussion Thread By AndrewJ, 5 hours ago Forum Air Source Heat Pumps (ASHPs)
	Interesting temperatures this morning: this is what I'm concluding so please correct me if my thinking is wrong! From a high of 23.5c at 11pm last night, the living room has dropped down to 22.0 at ...
	RE: Don’t Install a Heat Pump Until You Read This By JamesPa, 5 hours ago Forum Air Source Heat Pumps (ASHPs)
	Understood. Solutions I can see if you cant somehow squeeze enough out of the heat pump are Supplementary heating Replace UFH with rads (because then the slab is in contact with air at 20 not pipes ...

	RE: Don’t Install a Heat Pump Until You Read This By JamesPa, 5 hours ago Forum Air Source Heat Pumps (ASHPs)
	You need to insulate the edges and beneath - 'heat rises' applies only in fluids not solids, in solids the heat spreads isotopically. If you do this the slab does indeed become a large storage radi...
	RE: 10kw heat pump run in 24*7 data? By JamesPa, 5 hours ago Forum Air Source Heat Pumps (ASHPs)
	Vaillant are pretty good maintaining their sticker output or better, so I don't thing the heat pump is the issue, but it may well be that the estimated heat loss is the issue. I think I...
	RE: Commencing on an ASHP Installation Process By benson, 6 hours ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa yes probably. That said I was one of those people a few years back. Probably up until around 6 months before we got our ASHP installed tbh. I also just assumed up until a few months ago that ...
	RE: Don’t Install a Heat Pump Until You Read This By WantToBeGreen, 6 hours ago Forum Air Source Heat Pumps (ASHPs)
	It may be clutching at straws but heat has to go somewhere, is it possible to insulate the external edge of the solid floors so that the whole floor becomes a giant low temperature heat sink? Not ide...
	RE: 10kw heat pump run in 24*7 data? By cathodeRay, 6 hours ago Forum Air Source Heat Pumps (ASHPs)
	Apologies, I was being lazy, the answers to some of my questions are already in the thread: 9.9kw loss at -2, 10kW heat pump. But the supplementary question remain, how accurate are those figures? For...

	RE: 10kw heat pump run in 24*7 data? By cathodeRay, 6 hours ago Forum Air Source Heat Pumps (ASHPs)
	As @jamespa says, there is some sort of limitation, or rather imbalance. The difference between the set flow temp and actual flow temp isn't trivial, it is substantial. I would go back to basics: wha...
	RE: Don’t Install a Heat Pump Until You Read This By davidnolan22, 7 hours ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa hmmm..... one to ponder. I've no idea how dry or wet the soil is. the old part of the house is from 18th century. But, I've put a 20K floor, 20k kitchen down since then.... we are not diggi...
	RE: Grant 13kW Aerona3 - issues getting zones to temp By Crimson, 13 hours ago Forum Air Source Heat Pumps (ASHPs)
	So this morning marked 24 hours up for installer. Rooms weren't to temp as I expected. I instructed builder that I no longer wanted the installers on site - as in - you don’t instruct someone else, I ...
