	RE: Missing flow temperature in Heat Geek proposal By JamesPa, 5 days ago Forum Air Source Heat Pumps (ASHPs)
	To me this shows that they are, as I suggested up thread, winging it a bit/playing the numbers game based on their accumulated experience. We don't ask for detailed design specs of a car engine, we a...

	@editor the replies I received were as follows 1.There is the guarantee if you need it dont worry. 2.ΔT50 only refers to the radiator spec but yours will be taken at lower figure.(not mentioned anywh...
	RE: Missing flow temperature in Heat Geek proposal By cathodeRay, 5 days ago Forum Air Source Heat Pumps (ASHPs)
	Ye Gods! Trying to penetrate this stuff is like trying to drill a hole in concrete with a cocktail stick! And it is not helped at all by the recent MCS guidance and requirement changes. First, what I...

	Attachment : Screenshot_20261008_112325_My Files.jpg @l8againagain I think you need to look into it in depth.Heat geek proposal says the heat loss are for -3.6 deg C outdoor and 21 deg C indoor t...
	RE: Missing flow temperature in Heat Geek proposal By scrchngwsl, 5 days ago Forum Air Source Heat Pumps (ASHPs)
	Honestly I would just ask for the radiators to be replaced in the rooms you are concerned about. They don't cost much. You could do it separately but I think if they get fussy it's a red flag? In any ...
	RE: Missing flow temperature in Heat Geek proposal By L8Again, 5 days ago Forum Air Source Heat Pumps (ASHPs)
	@jo2255 You may be overthinking this. The maximum heat output of a 5kW Vaillant aroTHERM plus air source heat pump reaches up to 7.9 kWunder optimal conditions (at +7°C outside air temperature and hi...
	RE: Missing flow temperature in Heat Geek proposal By Mars, 5 days ago Forum Air Source Heat Pumps (ASHPs)
	Thanks @jo2255, @donciccio and others... your posts are making this discussion interesting because we now have two very similar proposals raising the same basic questions. @jamespa may well be right t...
	RE: Missing flow temperature in Heat Geek proposal By donciccio, 5 days ago Forum Air Source Heat Pumps (ASHPs)
	Ultimately I think I agree with @jamespa that while there's a level of opaqueness to what HG are providing, they are providing something that is more simple and requires less expertise from the user t...
	tepeo ZEB UK Support & Info Thread By Mars, 5 days ago Forum Wood Burners, Biomass, Small Scale, Biofuels & Other Heating Alternatives
	Heat batteries offer another way to electrify home heating. They use electricity to build up a store of heat, which can then be released through a wet central heating system when the home needs it. Th...
	RE: Missing flow temperature in Heat Geek proposal By Jo2255, 5 days ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa However, with MCS and BUS involved, I’m struggling to understand how this works in practice. As a business, Heat Geek can size a system however they consider appropriate for the property muc...
	RE: Missing flow temperature in Heat Geek proposal By JamesPa, 5 days ago Forum Air Source Heat Pumps (ASHPs)
	Having looked at all the posts I'm pretty certain that Heat Geek are betting that the 'standard' heat loss calculation is in fact an over estimate and that they can run at a sufficiently low flow temp...
	RE: Missing flow temperature in Heat Geek proposal By L8Again, 5 days ago Forum Air Source Heat Pumps (ASHPs)
	@donciccio You might be better posting these concerns on FB HeatGeeks for Homeowners. I say that because the forum often gets responses from someone from Heat Geek HQ. FWiW, the installer might not ha...
