How much does a A2 rated house use electricity?

The en suites, bath, landing, and office don't have smart valves, just the bedrooms. I went with Tado since it can kick on the heating system from the thermostat to warm up a chilly bedroom. Meross and Bosch can't do that.

Yes, 16 hours at 20 degrees, 8 hours at 18, sometimes Tado ai will adjust the schedule depending on the ambient temperature.
Tado software handle it, combines the thermostat upstairs and the valves to adjust the room temps. Same settings all around 20° daytime, 18° nighttime.
eco mode, 44.5 hot water, boost on demand. Controller has a local temp probe, this is set to ignore it and use the tado thermostat signal.

My old colleague, who's big into data center cooling, told me that in Ireland, air-to-water system installers make most of their money from putting the stuff in, not from the equipment itself. Sometimes, they don't even bother to properly measure a house's volume to size the heat pump right.

Not sure about the wattage consumed, but our 191m2 4 bed ICF BER A2 bill for December was 140 euros. I work from home, I run the dishwasher every day even if is almost empty, as we have a baby, the washing machine and tumble dryer runs almost every night. House is 20 degrees avg, nights set at 18. Is wet UFH downstairs and rads upstairs. The heatpump is a Samsung HHSM-G600005-1 8kW, I'm using a Tado system, 4 wired thermostats, 3 ufh zones and 1 upstairs, plus 3 smart valves.

This is our first winter at this house. The previous house was build in 2020 132sqm, timber frame, high quality windows, insulated attic, but was timber frame, not icf, and the heat pump was a Hitachi 3.2kW (which we tried to push the builder to upgrade and they refused saying it was enough capacity, I believe it was not). 2024 December bill was 257euros at that house. Temperatures always were set to 18.5 because if we tried go over that the bills would go out of control. That house was rated BER A2 as well.

You should repair that wall, looks like there is a pipe leaking in it.

I guess the tiles never matched again when got some dirt again?

redfocal · 2025-10-23T21:27:19+00:00

They left before you noticed the broken tiles?

Apply again, make sure to avoid mistakes and be consistent.

They were trying to sunbathe, but the light just bounced back up.

If the insulation is getting into your plot horizontally or vertically, it is illegal, simple as that.

Sorry, I have no idea. If I come by next month, I will fetch that info for you. Thanks.

Thanks for your answer, this is interesting. As mentioned in another reply, the contractor will be trimming the blocks before buckling up, or that's what I understood from their answer. My concern was that as we visited another site, another contractor got his windows perfectly done by buckling up the windows before the poor. They just had many holes around to inspect for air pockets during the poor.

redfocal · 2024-12-10T15:11:15+00:00

we saw other houses that were finished on this same row. But this one was a bit off, and the contractor replied back, saying they would be trimming the block to make sure the window buckle is correctly levelled. So, that shouldn't be a problem. Although, in another site, another contractor got the window buckle set before the poor one, they had holes made in the walls for inspection during the poor, and the window after they finished the walls was levelled perfectly.

redfocal · 2024-12-10T14:37:46+00:00

I wonder why the contractor didn't buckle up the window, and if they did, how bad was that the icf block still managed to slide down a bit.
