Hello!
I'll start.
Heated area 200m2 (2,153 sq ft)
KfW 55 standard
Mechanical ventilation with heat recovery
Current outdoor temperature 6°C (43°F)
Heating energy consumption including hot water 35 kWh
Electricity consumption 9 kWh
COP 3.88

24-hour average temperature -1°C (30°F), power consumption 19 kWh (internal meter, I always mention this because the actual consumption is probably 2-5 kWh higher), heat output 89 kWh

Unfortunately, my heat pump does not have a heat meter. The 24-hour consumption on February 15th was 21 kWh. The 24-hour average temperature was +0.8°C (33.4°F).

You just adjusted the temperatures yesterday, right?
I still don’t know exactly what you did. But if you only limited the maximum supply temperature at the top, then yesterday’s evaluation is basically useless.
Previously, you had been heating the screed with temperatures between 33 and 35°C (91 and 95°F). Now you limit the supply temperature to 30°C (86°F). However, the stored heat in the screed is still there.

She’s alive!!! From now on, everything will get better 😀 It was shaking badly, then one third of the system went offline.

Three colored tiles show PV generation, total consumption, and grid feed-in.

Here as well, for 1 hour now. Snow is falling off the roof. Unfortunately, the battery storage is still in standby mode. Starting tomorrow, it should start charging and supplying power.


Current values: PV 1.6 kW, consumption 367 W, battery 30%, inverter 1.5 kW, grid 1.2 kW.

No worries, you can only lose against Zaba 😀.

Then I’m all for kicking Zaba out of the thread due to unfair competition :p
