Wow, 3x80A is a bit over the top, isn't it? :)

Just looking at the device itself, you can find one for 40€. The electrician simply clamps it between the phases of the heat pump onto a DIN rail.
Isn't that a funding requirement nowadays? I think with us it was the BAFA funding that required it anyway.

Isn't that no longer a funding requirement nowadays? I think in our case it was the BAFA funding that required it anyway.

As far as I know, it is sufficient if the heat pump records it itself.

We (3 people, 180 sqm, renovated 60s building, living room temperature at 22-23 degrees, bathroom ≥23) are currently at 11-12.5 kWh per day, AT ±5 degrees in the evening but the stove is often on.

Wow, 3x80A is a bit much, isn’t it? :)

Just looking at the device itself, you can find one for 40€. The electrician just clamps it between the phases of the heat pump on a mounting rail.
Isn’t that a subsidy requirement nowadays? I think with us it was the BAFA subsidy that required it anyway.

The electrician just installed it like that, doesn’t really matter.
