Yes, running 24/7 using pure weather compensation (no thermostats at all, no timers or schedules, it's just fully on the entire time). The whole house, every room, stays at a constant 21.5-22C. This is too hot, but the house needs to dry out for a while after loads of building work.
Yesterday over 24 hours, average outdoor temp was 2C, heat pump used 28kWh to keep the house at 22C the whole time, which cost £4.20.
Last week, average outdoor temp was 10C, heat pump used an average of 10kWh/day to maintain average indoor temp of 22.5C, cost £1.50/day.

That's some great numbers

Thanks - that's great info.
I've got 19.9kWh (18 usable really with 10% SoC reserved) which I top up at 7p overnight. On average over the winter, I'm using about 30-40% of the battery, leaving about 11kWh so I could get away with just using the battery on most days which would mean a daily cost to heat of 70p.
Octopus is 28p per kWh in peak (5.30-23.30) so I would assume I would probably use, on really bad days, maybe 20kWh peak which would be £5.80 but I assume less as there's time overnight which I'd get the lower rate.

4.0 is still pretty great. I assume you're running basically 24/7 at that temp? What's it pulling per day in kW?
