	Are you an academic @lucia?
	RE: Hitachi Yutaki SCombi Heat Pump - Owners By JamesPa, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	OK, how do you know its reached the set temperature, and does it continue to heat the DHW at an elevated flow temp (and thus overshoots the DHW set temp)? If not what does it do (switch off entirely,...
	RE: Replacing my 18 month old Hitachi Yutaki ASHP By JamesPa, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	Its not so much challenging as seeking to understand. Your house cools very slowly so provided that the right amount of energy is put in over several hours (which, if the WC curve is correctly adjust...
	RE: Hitachi Yutaki SCombi Heat Pump - Owners By Sim0n0, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa Hi James The controller shows it’s still in DHW mode despite reaching the set temperature. It’s not on a timed program, it turns on at 45 and off at 48 - 24/7. It’s always worked fine until t...
	RE: Replacing my 18 month old Hitachi Yutaki ASHP By trebor12345, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	You always challenge my thinking! I don't specifically know why I think it's too long. My only thought is do other systems/users have that long time. Yesterday it did take some time to get heat into...
	RE: Confused by Flow Rates By Toodles, 3 hours ago Forum Air Source Heat Pumps (ASHPs)

	I’m trying to rule out a fault, could owners of above combination answer the following for me? Regardless of weather curves etc, can anyone confirm that if the Smart Controller is set (for example) to...
	RE: Grant Aerona circulation/system pump staying on By MikeFl, 3 hours ago Forum Air Source Heat Pumps (ASHPs)
	@damonc The only time the circulation pump on my HP runs 24x7 is when it's in "frost protection" mode i.e. OAT goes below 3C, when it stays running until OAT goes above 8C. At other times, it only run...
	RE: Help…my Nibe has faulted again. By JamesPa, 3 hours ago Forum Air Source Heat Pumps (ASHPs)
	Have you actually had a Nibe engineer in or just an installer. You probably shouldnt be paying anything if Google is right, it should be a warranty issue, Nibe are a premium brand so its disappointin...
	RE: Help…my Nibe has faulted again. By Fiona, 3 hours ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa thank you. At this stage (3rd winter with it cutting out when cold) I’m on the verge of seeing if it’s possible to replace the pump and putting a gas boiler back in. It’s costing so much mone...
	RE: Help me keep the faith with my air source heat pump installation By JamesPa, 3 hours ago Forum Air Source Heat Pumps (ASHPs)
	If the house is heating up I wouldn't worry about low deltaT. Lower is more efficient, at least up to the point where the power consumption of the water pump starts to become significant, which is li...
	RE: Hitachi Yutaki SCombi Heat Pump - Owners By JamesPa, 4 hours ago Forum Air Source Heat Pumps (ASHPs)
	Understood. Nevertheless this is, with high probability, a very simple and easily pinpointed fault that very likely doesn't require any hitachi specific (or even heat pump specific) knowledge to fix....
