	RE: Setback savings - fact or fiction? By JamesPa, 3 hours ago Forum Air Source Heat Pumps (ASHPs)
	Er dont you expect the mean 24hr temp to be lower on setback days. Thats sort of the point. The mean of interest is surely the mean IAT during the hours when you 'want' it heated. Or am I missing so...
	RE: Grant Aerona: Is there a setting to keep the 2-port valve open during pump blockade By Rhiannon, 3 hours ago Forum Air Source Heat Pumps (ASHPs)
	I have a Grant Aerona r290 9kw installed in a house with 10.03kW heat loss. It was designed with a target of 45C flow temp at -2.4 (capacity 10.47kW). When installed it had the weather compensation en...
	RE: Mitsubishi Ecodan R290 10kW performance By Sheriff Fatman, 4 hours ago Forum Air Source Heat Pumps (ASHPs)
	And to you too. Wishing you a very enjoyable festive season not worrying about COPs, and where the only flow rates of relevance are potentially the alcoholic ones!

	RE: Tinkerer's corner By AgentGeorge, 5 hours ago Forum Safety, Regulations, Tools, Plumbing & DIY Installations
	@majordennisbloodnok I am considering increasing my battery from 5 to 10kW, I’ll ask the installer if when you do that the time take to charge both batteries is 2x one, or the charger is configurable ...
	RE: Setback savings - fact or fiction? By cathodeRay, 6 hours ago Forum Air Source Heat Pumps (ASHPs)
	I have managed to get the data points in a scatter plot to scale according to a variable in R / ggplot, in this case using the 24 hour mean IAT as the scaling variable. This means we can get an immedi...
	RE: External pipework insulation By Transparent, 6 hours ago Forum Air Source Heat Pumps (ASHPs)
	They do? But that isn't apparent from the photos we're regularly seeing posted here on the Forum. The pictures we're seeing here are indicative of pipe insulation (external & internal) being appli...
	RE: New Fogstar 15.5kWh upright solution By Transparent, 6 hours ago Forum Energy Storage
	Inverters can pick up cell voltages and the overall battery voltage using the data-link to the BMS. You've stated that your battery has both a JK Balancer and a Seplos BMS.The video clip only shows on...
