Heat Pump Running Costs

Ah yes, it should be sq foot!

Yeah I have a

Yeah I have my own well and I have a treatment unit and softener, but still every year is amazing the anode is worn down to a nub!! Must check the hardness again and maybe adjust the settings in the treatment unit. The additional cost for the anode is €50

Do you mean Heatmiser thermostats? I have a daikin system controlled of Heatmiser neo thermostats - you can have both set temps and timers. You just set the stats you want to be set temps to the same temperate for all time windows. If you want different temperatures at different times you can adjust the temp then at different times on other stats. I am doing this where I let say the office get cooler at night by a degree or so but some other rooms are kept at a constant temp 24/7.

There are other options also for schedules and “recipes” but I haven’t needed any functionality beyond the above yet.

245m2 house. Zoned into open plan downstairs with UF at 22 degC, downstairs bedrooms with rads at 20 degC, and upstairs bedrooms (rarely used) with rads at 18 degC.

December usage was 584 kW.hr

Total 2025 was 3605 kW.hr at a cost of €980.

Still a bit of tinkering to do to get my system performing better (and costs down), but happy overall.

Are these the air to water things ? Ye I've been told there not worth it as they are heavy on electric, I've storage heaters but hoping to change that for something else 🙏

lots of posts here with people quoting monthly use and costs, should be easy to compare what you are currently paying?

I think it's like a over 6 euro a day or something for the 3 storage heaters but I do forget the air to water heats water too

Yes backup power is one of the reasons and cost saving with load shifting ect, all electric house.

My heat pump costs for Dec were 603Kwh costing appx €150. 16 radiators with thermostat at 21⁰ downstairs and 18⁰ upstairs, in A rated 180sqm detached house, Some folks here are able to get half this cost, most likely as they are using underfloor. Yes it's nice only having one bill but it's a big bill!

Yep, just heat pump. Which incidentally accounts for ~ 60% of my total electricity usage.

December 2025: 270sqm A1 rated. UFH upstairs and downstairs zoned into 11 zones controlled by Heatmiser smart stats.

Kitchen/dining/living and utility set to 22, play room 20, all bedrooms 20. Office 21.5 day (dropped to 20 at night) and hallways + an unused room 19.

Total of 342kwh heating and hot water. I don’t have the exact breakdown on day/night but it would be over 90% night rate as I can get through most days on my 20kwh battery.

Worth noting to anyone here using heat pumps with radiators, there seem to be magnetic radiator fans that clip into the bottom of the radiators to help the radiator radiate out heat. They are supposed to work very well with the low temperature radiators and heat pumps.

Yeah the Shelly's are great integrate well with home assistant also.
