Underfloor heating air-water heat pump. House too warm when the sun shines

Solid house with construction moisture in the first winter? That could explain it. Or a poorly adjusted heat pump.

Yes.

Let's see. I will first take the electric car out of the equation for this year, as I will try to charge 90% at work.

Hello everyone,
for many weeks we have had around 0 °C. My question to you is, how often does your heat pump turn on?
Currently at night down to about -3° and during the day at most +2 °C, our heat pump turns on 37 times within 48 hours. Of these, 30 times for heating and seven times for hot water.
How is it with you, I would be very interested. Thank you very much
Regards

what? :eek:
that's intense!
Sorry to be so direct, but the thing with the heating cycles is not normal.
The thing with the hot water almost shocks me even more...

Yes, there is probably something missing in the coordination. Mine runs continuously (modulating) and only pauses about every 3 hours for defrosting and twice a day for DHW (I have released two times, the rest is locked).

But it also depends on what kind of system you have. Fixed-speed, modulating. Compact unit, buffer, combined buffer, etc., etc.

We currently have 3 cycles per day. Our system modulates but is a bit too powerful for the house.
