	RE: Replacing Storage Heaters with a Heat Pump in a Stone Cottage By JamesPa, 2 days ago Forum Air Source Heat Pumps (ASHPs)
	I don't know what calculation is done by people fitting combis, but that one makes no sense for combis or heat pumps and vastly overstates the requirement unless your dhw use is quite extreme. You are...
	RE: Replacing Storage Heaters with a Heat Pump in a Stone Cottage By Paul1098, 3 days ago Forum Air Source Heat Pumps (ASHPs)
	I assume the 2.5 - 3kW required to heat the hot water cylinder is added to the total house heat loss to size the A2W heat pump as per a typical non combi gas boiler?
	RE: Vaillant ecoTEC Plus - Flow Temp and Set Up By Batpred, 3 days ago Forum Air Source Heat Pumps (ASHPs)
	@trebor12345 I have been meaning to get home assistant to tweak the legionaries cycle for once a month, at the moment it is also weekly…
	RE: Adding additional Solar Panels to a DC coupled battery system By EtchedPixels, 3 days ago Forum Solar Photovoltaic (PV)
	@transparent I was replying about the accuracy of "AI" - viz that the AI was busy telling me about nonexistent octopus plug in solar kits and some of the AI diagrams on how to wire things, which would...

	I too found the same thing, so reduced the hysteresis. Works like a dream now! The Legionnaires cycle is still a little problem in that the water is too hot.
	RE: Adding additional Solar Panels to a DC coupled battery system By Transparent, 3 days ago Forum Solar Photovoltaic (PV)
	Source references please @etchedpixels The only reference I can find to Octopus and plug-in solar in this topic is what you've just posted yourself. Where are you reading it is how to wire a UK plug ...
	RE: Replacing Storage Heaters with a Heat Pump in a Stone Cottage By JamesPa, 3 days ago Forum Air Source Heat Pumps (ASHPs)
	@cathoderay The 'constant' has dimensions. Its the volumetric heat capacity of air in Wh/(Km^3) Thus if ach has the dimension 1/h it all works out.
	RE: Indevolt Batteries UK Support & Info Thread By Transparent, 3 days ago Forum Energy Storage
	SunSynk hybrid inverters also have the capability to assign one or both of the local generation inputs to accommodate a technology which isn't solar PV. The MPPT mechanism is replaced by a power-curve...
	RE: Replacing Storage Heaters with a Heat Pump in a Stone Cottage By Paul1098, 3 days ago Forum Air Source Heat Pumps (ASHPs)
	@etchedpixels This house is fairly straight forward as far as plumbing goes but it's not a typical ASHP job as it includes all the central heating pipework. The existing hot water tank needs to be rep...

	Yes
	RE: Is This Initial Free Quote From Octopus Trusted Partner Reasonable? By EtchedPixels, 3 days ago Forum Air-to-Air Heat Pumps & Air Conditioning
	If you've got a sash window or a door you can remove the plastic panel from and rearrange with the external unit outside cut a slot and then put back and insulate a bit then you could just get a 4kW M...
	RE: Adding additional Solar Panels to a DC coupled battery system By EtchedPixels, 3 days ago Forum Solar Photovoltaic (PV)
	Also frequently very wrong - handing out diagrams for adding a spur to a UK electric circuit that were definitely not conventional, and claiming that Octopus had sold out of plug in solar kits several...
