	RE: Setback savings - fact or fiction? By cathodeRay, 49 minutes ago Forum Air Source Heat Pumps (ASHPs)
	Or perhaps post something here, suitably anonymised, though we already know is SE England? For folks using ToU tariffs and concerned about their carbon footprint, surely such information is gold dust?
	RE: Setback savings - fact or fiction? By Majordennisbloodnok, 56 minutes ago Forum Air Source Heat Pumps (ASHPs)
	I’ve been capturing carbon intensity into Home Assistant for quite some time. There was a hiatus with the API that resulted in my having to ditch what I had and start again, but I’ve got all the data ...

	@jamespa — pickling the little grey cells in hopped water is nothing compared to the effects of using AI! The thing that stuck me about the AI response was the Morning Peak (defined rather oddly as 06...
	Poll for Time of Use, tariffs, technology By Tim441, 1 hour ago Forum Electricity, Tariffs, Monitoring & Providers
	It might be interesting to see which technologies are used and which tariff? Or maybe there are so many variables that it's not possible to get many takeaways without deeper analysis? I've listed Oct...
	RE: Setback savings - fact or fiction? By JamesPa, 1 hour ago Forum Air Source Heat Pumps (ASHPs)
	Fair enough, I wanted some quick insight and didnt know where to look for the data other than the obvious which i had already tried. Having got the result I thought about it (hopefully reviving some b...

	Don't do it! Every time you use AI, a few more of your little grey cells die. Plus the answer looks very questionable to me.

	@judith — it's an interesting analysis (as his analyses usually are) and he does in fact do something similar to what I have done, though he uses a different language (counterfactual, a long modern wo...
	RE: Setback savings - fact or fiction? By Tim441, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	@jamespa yes, i should add i also schedule DHW heating for night time. Most of the time we use less than full tank per day so heat to 50deg at cheap rates. Daytime boosting to just 40deg if/when neede...
	RE: Setback savings - fact or fiction? By JamesPa, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	OK so I resorted to AI. here is what duck.ai says Morning Peak (6 AM - Noon): 80-100 gCO₂/kWh. Increased contribution from renewables right after sunrise, particularly solar. Afternoon Dip: 70-80 gCO...
	RE: Setback savings - fact or fiction? By JamesPa, 2 hours ago Forum Air Source Heat Pumps (ASHPs)
	Absolutely. I tend to call this a set forward. I also have a similar night-time tarrif, I don't bother with a set forward but I do my DHW cycle at night which is the least efficient time to do it bu...
	RE: Setback savings - fact or fiction? By Tim441, 3 hours ago Forum Air Source Heat Pumps (ASHPs)
	There are 2 issues here. The Topic is Setback Savings but the vast majority of the discussion has been around ENERGY usage. However with ToU tariffs increasingly used by the majority of owners of heat...
	RE: Replacing my 18 month old Hitachi Yutaki ASHP By JamesPa, 3 hours ago Forum Air Source Heat Pumps (ASHPs)
	@trebor12345 Ok that makes more sense and leads is in a different direction. The cycles are about once per hour and there is a distinct plateau. Basically I can't see a problem. As such I wouldn't ...
