	RE: Mitsubishi Ecodan R290 10kW performance By Ecoste, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@grahamf It is not cycling, it ran constantly for 5 hours and then only dipped by 2 or 3 degrees for 10minutes. See attached report Attachment : Heat Pump Performance.pdf
	RE: Help me keep the faith with my air source heat pump installation By AdamK, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa it doesn’t seem to matter the outside temp it cycles about once per hour. I tried adjusting the compressor setting that is normally set to -60 to -100, which apparently affects cycling, yet n...
	RE: Help me keep the faith with my air source heat pump installation By JamesPa, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Is it still cycling, at what FT/OAT? Mine appears currently to be at the 'sour spot'. OAT about 11C, still just cycling, COP 3.9, target FT ~32. If the OAT goes a bit lower it stops cycling and COP ...
	RE: Daikin Octopus installation update - I saw my first defrost. 😍😂 By JamesPa, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Is it possible there is air still trapped in the system. Mine took a month to clear and despite the presence of an auto bleed valve one radiator needed daily bleeding. Alternatively have you got an ...

	Even during the cold snap still getting crap scop 3.1. But hot water (eco) and heating are both down to 3.1.

	Well took the intakleen apart expecting that to be blocked again and it was mostly clear. So took the strainer out of the inta isolation valve and it was pretty grubby. So cleaned everything up, teste...
	RE: Mitsubishi Ecodan R290 10kW performance By JamesPa, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	I cant remember what Ecodan reports but some heat pumps report energy consumed and environmental gain. In this case cop = energy consumed/(energy consumed + environmental gain). Still not good, jus...
	RE: Mitsubishi Ecodan R290 10kW performance By GrahamF, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	It may be cycling on and off a lot. Do you have any graphs of the compressor frequency, water outlet/inlet temperature, other relevant data... over say a 24 hour period?
	RE: Daikin Octopus installation update - I saw my first defrost. 😍😂 By RadWhisperer, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	So after a week of playing with the LWT mode I'm now back to setting my WDC LWT minimum flow temp to 25C. Below this the HP does not resume reliably to the zero setback schedule periods even if the ou...
	RE: Battery disconnected By Batpred, 2 weeks ago Forum Energy Storage
	Apologies as my post clearly interrupted this flow. When I read one of the posts, I thought it could be understood that in case an electrician does some work, they need to put everything right. I beli...
	RE: One room is colder than the rest of the house By JamesPa, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	I would personally be sceptical about reaching any conclusion that goes against the norm of heat pumps. In the end the Cosy is a heat pump, subject to the same laws of thermodynamics as every other ...
	RE: Melpump Users Anywhere? By F1p, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@davidalgarve So Air-to-Air talks a different version of the same protocol, this adapter is only compatible with Air-to-Water units. The principle of operation, to answer your question, is that the se...
