Ahh that makes sense thank you. We have a similar size house, if a little smaller (210 vs 230m2) and thermostats mostly set to 18/19. Our total usage (literally everything and we are very heavy users too as a busy family of 4):
Sep - 524 kwh. £111
Oct - 843 kwh. £180
Nov - 1285 kwh. £269
It's still reasonably affordable to us at the moment, although I'm nervously anticipating £300+ electricity bills in Jan/Feb although we are using the logburner a bit more in the evenings just to get the lounge nice and toasty without too much trouble. Have set my DD at £250 and hoping it all evens out over the year although the forthcoming price cap change next April is making me sweat a bit more....
I've had to set our direct debit for £600 a month as with the new prices we will be hitting £8k a year. The ASHP will make up about £3500 of that.

@George, that's a staggering amount of money. Ouch!

Wow...that's a huge amount indeed.
Indeed. The cost of going green with the ASHP has not been rewarding so far 🤣

Not much point as we'd use pretty much all of what would be produced by most domestic sized Solar PV installations.
I'm also not a fan of batteries due to the costs, lifespan of the battery and payback unless you are willing to do it cheaply yourself which I don't have the time or energy to do.

George,
As I have repeatedly tried to convince people, set your system for weather compensation.
In a perfect world I would but part of my house is probably over 70-80 years old with little to no insulation and other parts are brand new and fully insulated. Getting all rooms to behave in a similar manner with a lower flow temp is impossible being controlled by weather compensation. Its better in my situation to prioritize keeping the cooler rooms warm and directing heat to where it is needed most.
With underfloor heating you can't be playing catchup when its really cold as it can take a 12+ hours to react. Its even worse if living in an exposed area as we do as the south west facing rooms take a beating and others remain warm.

Hi George,
I can see you have one of those un-user friendly houses, have you considered moving. 😎
Without knowing the exact details it is difficult to comment fully. Larger output heat emitters in the colder areas and balancing of your system could go some way to lowering the water flow temperature and improving efficiency.
I've just published this article about our experience with E.ON and how our default tariff, on a direct debit, exceeds the price cap: https://renewableheatinghub.co.uk/are-you-being-overcharged-by-your-electricity-provider
I would recommend that everyone that has been switched recently double check their tariffs to see that their new providers aren't trying to pinch a few p/kWh without them knowing this.
Our tariff was supposed to drop (probably in line with the price cap) when we set up our direct debit, but this has not happened.

Mars, I've heard about people moving to a SoLR initiallly being quoted a pay-on-receipt tariff rather than a DD one. It was later sorted when supply started and DDs were set up. Could this, or something similar be what's happened? It's hard to believe Eon would try and get away with charging over the cap.
