	RE: Heat loss calculations and how they work in conjunction with heat pump sizing By JamesPa, 3 weeks ago Forum Safety, Regulations, Tools, Plumbing & DIY Installations
	There is some truth and perhaps even relevance in that! It sounds like just the sort of house for which the standard fabric calculation could easily be widely out (because of the variable constructio...
	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...
	RE: Battery storage to run Heat Pump. By Transparent, 3 weeks ago Forum Energy Storage
	I doubt that anyone would want to run batteries made of two different chemistries in parallel,but if you restricted the voltage range of the inverter to that of the LiFePO4 cells, then it's theoretica...
	RE: Homely Smart Controller By Toodles, 3 weeks ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	@papahuhu I did try Smart+ during the first 2 years but never solved the problem of maximum setting dictating the rest of the settings. They may have improved the algorithm more recently, I don’t know...
	RE: Heat loss calculations and how they work in conjunction with heat pump sizing By Judith, 3 weeks ago Forum Safety, Regulations, Tools, Plumbing & DIY Installations
	“Anyway, we know that the assumption the heat pump will be running continuously is based on the fact a cylinder is assumed to be always part of the solution. This essentially means unless it is a mass...
	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
	In the context of my previous post, I'm not sure what point you're trying to make here. As for putting batteries through 8000 cycles, I would agree; not much of a problem. However, with Octopus Agile ...
	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
	Yes, but HA allows separation on concerns and also resilience through multiple paths of failure. To be honest, never enough! Dream high and be realistic I'd say. With batteries doing 8000 cycles I wou...
	RE: Battery storage to run Heat Pump. By Batpred, 3 weeks ago Forum Energy Storage
	@transparent makes sense... In general they look very similar. But to add a battery made of sodium cells we would probably need a separate inverter to one already supplying lithium. And I can see the ...
	RE: Homely Smart Controller By Papahuhu, 3 weeks ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	@toodles I wasn’t getting very far, so contacted homely. Haven’t tried it yet, but this is what they advised me, before I get a smart+ subscription I was wondering if you have ever tried it please?: ...
	RE: Isolating the system for a planned power cut By Transparent, 3 weeks ago Forum Solar Photovoltaic (PV)
	This would mean a lot more to us if we could see photos. 🤨 Every time circuits are altered or added on my set of consumer units I take photos and add lots of pretty coloured labels. Here's th...
	RE: Battery storage to run Heat Pump. By Jeff, 3 weeks ago Forum Energy Storage
	I can't see electricity pricing falling, the government has gone quiet on savings and only really talks about reducing spikes due to things like the Ukraine war. My personal thoughts... CfD auction pr...
