	RE: DHW Efficiency By Morgan, 2 weeks ago Forum Domestic Hot Water & Cylinders
	@transparent I am running an anti-legionella cycle (60c), but I need to remember how to get to it again to see the intervals. But that needs to remain, doesn't it?
	Mitsu PAR-WT60 Wireless Controller By DavidAlgarve, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	It is early days and rather warm weather, but I think that my Wireless Controller is controlling the radiator system, but the 'water tap' touch switch does not seem to have any effect and certainly do...
	RE: DHW Efficiency By Transparent, 2 weeks ago Forum Domestic Hot Water & Cylinders
	Yes, please do try it @morgan and let us know what you find. How long would you need to conduct such a trial in order to know the effect on COP with a reasonable level of accuracy? Can you also say i...
	RE: My experience with 3 heat pump surveys: Heat Geek, British Gas & Octopus By DREI, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	OK so from what I see now, the fans look similar to fan units used in data centres on servers, routers, network switches, storage device etc. Assuming these fans are powered, so need to be plug...
	RE: My experience with 3 heat pump surveys: Heat Geek, British Gas & Octopus By jords, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@editor I can understand why. But it’s a shame they don’t give you the details that go into the outcomes. One would assume the formulas they are using are the same. So the variables they put in must d...
	End of Summer Time Reminder to Ecodan owners By downfield, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Public Service Announcement to all Ecodan owners: don't forget to turn off Summer Time in the Initial Settings menu - the software isn't clever enough to self adjust, unfortunately...
	RE: My experience with 3 heat pump surveys: Heat Geek, British Gas & Octopus By DREI, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	In all seriousness, if the engineer doesn't use thermal imaging and a air tightness measuring unit, then it will never be accurate, just best guess estimate, and none of them will be correct, e...
	RE: DHW Efficiency By Morgan, 2 weeks ago Forum Domestic Hot Water & Cylinders
	@editor is that correct? My installer set DHW to 50c and suggested it remain there. I wonder if a 5c difference will leave me with sufficient hot water. (250L tank). I might have to give it a try be...
	RE: My experience with 3 heat pump surveys: Heat Geek, British Gas & Octopus By JamesPa, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	@mars it seems madness giving you advice but I feel I must. Whatever figure(s) you get somehow find a way to check them against your oil consumption or previous Heat Pump heat delivered. Its a sense...
	RE: My experience with 3 heat pump surveys: Heat Geek, British Gas & Octopus By JamesPa, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Mandatory sense checks based on measured consumption (or something else if measured consumption not available). Only way forward IMHO. If the sense check and fabric assessment stack up to within the...
	RE: My experience with 3 heat pump surveys: Heat Geek, British Gas & Octopus By Judith, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	The air changes per hour in the leakage values is the most guessed parameter. Assessors have guidelines based on the house build date. If you have an actual measurement then the best designers can use...
	RE: DHW Efficiency By Mars, 2 weeks ago Forum Domestic Hot Water & Cylinders
	@transparent, that’s a bang on suggestion. 45C DHW tends to be the sweet efficiency spot for most heat pumps.
