	RE: Recommended home battery inverters + regulatory matters - help requested By Batpred, 24 hours ago Forum Energy Storage
	The diagram below is a simplified view of the internals of the Solis S6 hybrid. The earth shows against the grid port connects to the consumer unit and the DNO (in my case). There is also an additio...
	RE: Heat pump not reaching flow temperature By JamesPa, 24 hours ago Forum Air Source Heat Pumps (ASHPs)
	@davec Ive had a look at the screenshots. Lots of the parameters are things you wouldn't want to touch but: Im guessing H43 and H44 are the two FTs for the WC curve and P18 and P19 the corresponding ...
	RE: Vaillant aroTherm not heating with many faults By JamesPa, 1 day ago Forum Air Source Heat Pumps (ASHPs)
	When I had a series of apparently unrelated faults my installer turned up, checked the flow rate using the test menu, and cleaned the filters (two - a mag filter and a gauze filter immediately behind ...
	RE: Heat pump not reaching flow temperature By JamesPa, 1 day ago Forum Air Source Heat Pumps (ASHPs)
	At this stage I would say no as gross underestimation of the loss is not the most likely cause of the problem. More likely causes are (a) the heat pump, though badged 11kW, doesnt actually do 11kW at ...
	RE: Recommended home battery inverters + regulatory matters - help requested By JamesPa, 1 day ago Forum Energy Storage
	I cant see how that is the case if the earth is provided by means of a bond to the metal outer sheath of the incomer; no cut (other than one in your driveway of which you would surely be aware) can re...
	RE: Heat pump not reaching flow temperature By DaveC, 1 day ago Forum Air Source Heat Pumps (ASHPs)
	Thanks @jamespa and thanks @johnd (hope I haven’t hijacked your thread too much). I’ll hopefully hear back from our installer or the manufacturer early next week and will post if there’s anything usef...
	RE: Recommended home battery inverters + regulatory matters - help requested By Transparent, 1 day ago Forum Energy Storage
	I too think that the Solis earthing diagram is confusing. As I see it the situation is this... We commonly have circuits which are protected by an Earth-Leakage Trip, such as an RCD or RCBO.They 'meas...
	Vaillant aroTherm not heating with many faults By Anon67, 1 day ago Forum Air Source Heat Pumps (ASHPs)
	I have a 3 year old 10kW vaillant aroTherm heat pump connected to dhw and ufh. The heat pump kicks in on demand for hot water but when it comes to heating it faults, getting a mixture of faults F.732...

	Thanks for the clarification.
	RE: Considering MLCP (Multi-Layer Composite Pipe) for ASHP By JamesPa, 1 day ago Forum Thermostats, Volumisers, Buffer Tanks, TRVs, Pumps, Piping, Valves, Radiators & Controls
	OK, TBH I dont know enough about MLCP to comment with any authority. The simple message so far as I am aware is: Nothing inherently wrong with plastic pipe but it has a smaller internal diameter and ...
	RE: Predicted Heat Loss from MCS calcs vs EPC vs actual By Tim441, 1 day ago Forum Air Source Heat Pumps (ASHPs)
	My gut feeling is that the heat pump is right sized. it does not seem to cycle It heats the house comfortably costs/usage seems reasonable - especially against predictions by EPC or MCS the spare cap...
	Predicted Heat Loss & Needs from MCS calcs vs EPC vs actual By Tim441, 1 day ago Forum Air Source Heat Pumps (ASHPs)
	LG therma V installed 2020. 16kw monobloc. Initially on fixed flows then weather compensation Looking back at the info from design in 2020 EPC 2020 predictedThe annual Space Heating requirement for y...
