Air-water heat pump current consumption and data

Bleeding and refilling, don't you have a cartridge in the basement?

Of course, one should get to the bottom of the cause, although the last few weeks have been an extreme case.

we have an appointment for consultation in 3 weeks, three neighbors will participate of course in compliance with Corona :-)

No, we don't have anything like that.

And? Have your pumps been running today?

Ours have been at a standstill since this morning until noon.
4 kWh consumption. I need to take a closer look at the control system.
Based on room temperature or actual outside temperature, it probably could have turned off at 10 a.m., but the averaged temperature (currently set to 16 hours) was still 7 degrees then.
I haven't really figured out yet how which control variable affects what.

My heat pump still runs twice a day. I checked again. The shutdown is not set to 12 but to 10 degrees, but it is not reached due to the cold temperatures at night. Probably again in March.

Yesterday, the total gas consumption was 16.8 kWh, but with so much sun, the grid consumption is only 4 kWh.

The whole topic makes me so mad that I quit my job and took a position with a well-known system manufacturer. I will put an end to the buffer tanks and mixing groups! :p

I will turn off the buffer tanks and mixing groups!

:-D Was there a recent reason or the accumulated dissatisfaction with the overall situation? :p
