Air-water heat pump current consumption and data

when did you "disconnect" the basement? And haven't you been running your fireplace in the last few days?

The consumption would be really great, but watch it for the next few days. At the moment you disconnect the basement, the consumption naturally drops at first. However, the basement will gradually cool down. As a result, the heat transfer from the ground floor to the basement increases again and the "consumption of the ground floor" suddenly rises again if you want to maintain the temperatures (on the ground floor). (Unless you had insulated the transition between basement/ground floor). However, this effect takes a few days; it doesn't happen overnight.

Nevertheless, I think this is a very good consumption.

The basement has been off since 01.01.

A different question. At what temperature does your heat pump turn off for heating? I set it to 13 degrees, so the average over 48 hours.

Who has it set even lower and what has been the experience? We have a very high solar yield at least on the ground floor. The upper floor can’t keep up with that, but downstairs it gets very warm without lowering the blinds in full sunlight. At least that doesn’t bother me when the underfloor heating is off.

I also set the heating limit to 13 degrees once, but I cannot provide any experience as I only moved in at the end of November. Everything is still not very representative in terms of the values.

that could explain the low consumption. We have not seen a ray of sunshine for months. On a sunny day, we also consume about 30-50% less heating energy.

We currently have about 25 kWh/day consumption, of which about 16 kWh/day is for the air-water heat pump for 50-60 kWh heating and 6 kWh hot water. Photovoltaics currently 0, as we have between 15-30 cm of snow. Temperatures hardly above -1*C and down to -10*C
