	RE: Starting Our Heat Pump Journey: 1962 build 3 bed detached house By AndrewJ, 17 hours ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa I used 9MWh of gas but the heat loss was originally calculated at around 8.5kWh and a 9kW heat pump installed. It was subsequently recalculated to 7.5kWh but I actually think it is better th...
	RE: Starting Our Heat Pump Journey: 1962 build 3 bed detached house By JamesPa, 17 hours ago Forum Air Source Heat Pumps (ASHPs)
	And that is the whole point really. The ofgem standard house (medium) consumes 11.5MWh of gas per year so is well less than 7kW. The fact it's the ofgem standard tells you are lots and lots of them....
	RE: Vaillant service impasse By JamesPa, 18 hours ago Forum Air Source Heat Pumps (ASHPs)
	I'm not sure why you would want to make it more difficult for busy people to respond which sending it by snail mail does. By all means do both (saying that this is what you have done) but email...
	RE: Starting Our Heat Pump Journey: 1962 build 3 bed detached house By bobflux, 18 hours ago Forum Air Source Heat Pumps (ASHPs)
	Mine only complains if flow is catastrophically low, otherwise it simply works at higher deltaT, up to 10°C or even 20°C, with a corresponding drop in efficiency of course. But it runs fine, so if you...
	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 JamesPa, 18 hours ago Forum Air Source Heat Pumps (ASHPs)
	Hmm, not so sure personally about the title. Who is it aimed at? Presumably not those who want a heat pump because the title doesn't include 'and how to avoid it'. Is it aimed at people who have al...
	RE: Starting Our Heat Pump Journey: 1962 build 3 bed detached house By JamesPa, 19 hours ago Forum Air Source Heat Pumps (ASHPs)
	Yes and yes, although I haven't seen many here which are down to this, so I wouldn't count it as a top failure mode based on what we see here. Most installers would, I hope, catch this when they commi...

	+1 #4 Primary pipes too small so not enough flow, but this one is easy to catch

	RE: Mitsubishi Ecodan FTC6 settings By F1p, 19 hours ago Forum Air Source Heat Pumps (ASHPs)
	I was just replying when i saw your edit drop in! 🙂 The default behaviour after any power loss is the Ecodan will run a hot water cycle - i suspect it was this which started.
	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, 20 hours ago Forum Air Source Heat Pumps (ASHPs)
	The circus surrounding the heat pump journey is at the centre of my new book, Britain’s Heat Pump Shitshow: How Installing a Heating System Became a National Nervous Breakdown. It is not an attack on ...
	RE: Mitsubishi Ecodan FTC6 settings By Clockworks, 20 hours ago Forum Air Source Heat Pumps (ASHPs)
	OK, I bought one of the dongles q couple of weeks ago, finally fitted it this morning. Powered up the FTC6, and was a bit surprised that the heatpump fired right up, despite the Mitsubishi remote stat...
	RE: Wood burner with ASHP - direct air? By JamesPa, 21 hours ago Forum Wood Burners, Biomass, Small Scale, Biofuels & Other Heating Alternatives
	@lucia FWIW installed a woodburner some years ago. The combustion air is drawn from the underfloorboard space through a vent near the burner. I cant feel a draught (because the burner itself is pr...
