Air-water heat pump current consumption and data

I think a hysteresis of 2 would currently be clearly better than 1.5, right?

Consumed 20kwh yesterday, but average temperature only minus 1.8 degrees

More efficient for sure, but I want the heat pump to start running when the sun is shining. It doesn’t help me if the thing turns on at 5 p.m. or midnight when the photovoltaic system isn’t producing anything. Grid consumption since 18.02. is less than 20kWh. But from the day after tomorrow, that will probably be over.

How often and for how long has your heat pump been running?

And we already set a 2k hysteresis a few weeks ago.

Ours turned off yesterday at 8:00 and only turned back on at 6 PM.

just work with a day boost

With photovoltaics, I would also recommend a daytime increase. And to set hot water blackout periods so that hot water is produced during the first heating cycle at midday.

It turned on three times, I think each time for 3 hours.

How long does one storage charge with photovoltaics last you? We have a 190-liter storage tank with a hot water temperature of 46°C; I am still experimenting with the charging times because of photovoltaics. The problem is somehow that if two people want to shower one after the other, the second shower curtain already feels noticeably cooler when the last storage charge was 4-5 hours ago.

Currently, I charge the thing with hot water in the morning, at noon, and in the evening, which I would like to move away from. Circulation runs only 5-10 minutes in the morning.

What is the best way to proceed to optimize the hot water issue towards photovoltaics?
