Air-water heat pump current consumption and data

In the last 24 hours, the heat pump has consumed 40kWh.
AT=-10C

At the AT I have 32 degrees or 28 degrees. My heating curve therefore seems to be a bit steeper. Let's see how the temperatures look tomorrow morning. I think your consumption is really good.

How big was your house?

Heated area is 218m2. Last night it was really cold... my heat pump lets the return flow run quite low. Compared to yesterday evening at 9:00 PM, the house is also slightly cooler.

Phew, you have a modulating one! Then it would make sense to increase the runtime, first set the hysteresis back to 2 degrees and then lower the heating curve, that way it should run longer.

I will do that today.

So final result after 24h: 160 kWh heat output and 47 kWh power consumption. Annual performance factor 3.5

Positive: Trouble-free operation, which is already very good. Temperatures in the house around 21 - 22 degrees, just the way we want it.

Now consumption would still have to go down by 20%, then it would be perfect. But it seems to be more due to the high heat output than the efficiency of the pump.

The AZ doesn't look bad for the temperatures now, I think it will only get better if you manage to get your heat pump running.

I will switch to hysteresis 2 instead of 1.5, that will surely help a bit. I don't want to lower the heating curve right now, then it will get too cold in the bathroom. The only thing left is to find out where the heat is diffusing to. Today I'll turn the ventilation down one notch. The new hydraulic balancing also requires at least 2 days before it shows any effect.

So I'm looking for errors and discovered condensation on the window, but there is a new post about that. Stay tuned! :)
