Air-water heat pump current consumption and data

Haha. I have heat lamps in the basement with bushy plants that smell so weird.

No kidding, I'm currently running the unit at 25/20.5/0 with 2K hysteresis. The house is a Kfw55 with a basement, just like yours. But as I said, you can't kid yourself, the heat pump can run in the other direction at any time. See posts from the weekend.

The outside temperature yesterday at 11:30 a.m. was 1.4 degrees according to Netatmo. [ATTACH alt="CE6B6375-D70E-4AEA-9321-7BD46B6B2599.jpeg"]56089[/ATTACH]

Also, the worst days/nights are still to come. Yesterday and today I heard that there is currently a special winter weather pattern over the polar region that will bring us one of the coldest winters in years until at least mid-March.

Nothing special. Like everywhere else, KG 12cm below and lateral perimeter insulation.

The same floor structure in every storey. 22cm concrete and floor structure 16cm (=insulation, screed, tiles). Cold roof insulated with 24cm ETICS. Exterior walls 36cm T9 with some special solar plaster (marketing speech)

But the blower door test was extremely good. I only remember that I was surprised.
