	RE: Setback savings - fact or fiction? By Toodles, 8 hours ago Forum Air Source Heat Pumps (ASHPs)
	@sunandair I’m attaching a plot of January so far with OAT and defrost data for my cosy little corner of the SE of England. Regards, Toodles. Attachment : IMG_1464.jpeg
	RE: Setback savings - fact or fiction? By JamesPa, 8 hours ago Forum Air Source Heat Pumps (ASHPs)
	This is an interesting and very useful observation, albeit one limited to a relatively small range of temperatures (which we are experiencing a lot of just at the moment). If you can shift energy pro...
	RE: Running from backup generaor in powercut? By Toodles, 8 hours ago Forum Air Source Heat Pumps (ASHPs)
	@editor It is just as well that you possess some fossil fuel burning devices! But I do feel for you both nevertheless. We have been lucky in the SE of England with just heavy rain for a few hours and ...

	@toodles yes it was a bit excessive getting 2 defrosts in one hour. I think it must have been the changing climate while it was still cold. We normally get away with 1 defrost every hour or a bit long...
	RE: Fan is clipping ice build up from the front of unit. By Toodles, 8 hours ago Forum Air Source Heat Pumps (ASHPs)
	@papahuhu I find that the ‘Homely’ OAT (obtained, as you say, from the cloud) can be at variance with that reported for my local area by Amazon (notsosmart) speaker. Sometimes they agree but other tim...

	When we operate a setback we are reliant on the insulation in our house to ensure we only lose about 1.5C to 2C room temperature this also means the internal water temperature in our pipes rarely need...
	RE: New Mitsubishi Ecodan 11.2kW installation - L9 errors and maybe more By anotherdaveuk, 9 hours ago Forum Air Source Heat Pumps (ASHPs)
	Great to hear! I just figured this out a day or two ago - I had assumed that the two ends of the curve would just extrapolate and only used -2C because that is what Google gave me as a good example &...

	@robssunandair That is a lot of defrosting! Perhaps we live in a drier patch just hereabouts. Attachment : IMG_1463.jpeg Regards, Toodles.
	RE: Recommended home battery inverters + regulatory matters - help requested By Transparent, 9 hours ago Forum Energy Storage
	No. That's uncommon. It goes back to the days when homes had a separate off-peak meter. As I wrote below my diagram, a separate isolator is required if an electrician needs to work in that fir...

	This probably makes it simpler to see... Attachment : image.png In James's case, perhaps the simplest is to make the existing consumer unit become the UPS consumer unit and have ...
	RE: Setback savings - fact or fiction? By SUNandAIR, 10 hours ago Forum Air Source Heat Pumps (ASHPs)
	Hi @toodles…. Comfort is, of course an essential need of any heating schedule. We operate a setback which aims to give us 19.5C by 9am and 21 usually by 3pm . If we wanted a higher temperature than th...
