	RE: Heat loss calculations and how they work in conjunction with heat pump sizing By Toodles, 3 weeks ago Forum Safety, Regulations, Tools, Plumbing & DIY Installations
	@batpred There will be times when the 8 kW heat pump starts up with a surge much higher than 2 kW and also when adverse weather drags the COP down, there may well be periods where that same pump could...
	RE: Heat loss calculations and how they work in conjunction with heat pump sizing By Majordennisbloodnok, 3 weeks ago Forum Safety, Regulations, Tools, Plumbing & DIY Installations
	That doesn't make much sense. HA can be implemented with as great a degree of redundancy as you might wish, and many different strategies for doing so - ultimately overkill for almost all domestic sit...

	RE: Heat loss calculations and how they work in conjunction with heat pump sizing By Batpred, 3 weeks ago Forum Safety, Regulations, Tools, Plumbing & DIY Installations
	Apologies if required Judith, as I had no intention to offend anyone! And no offense taken. Of course I am not suggesting a normal socket being used. Anyone would be best advised to use a certified ...

	RE: Heat loss calculations and how they work in conjunction with heat pump sizing By Batpred, 3 weeks ago Forum Safety, Regulations, Tools, Plumbing & DIY Installations
	Having HA concerning itself with what are aspects more likely to change like pricing and having to take into account a growing number of systems seems more future proof. Still, given the way that many...
