ᐅ Air-to-Water Heat Pump: Current Consumption and Data

Black walls and tiles?

What is your total electricity consumption? We use 10 kWh per day. That would leave only 10 kWh for hot water and heating. Physically, that’s impossible.

I already mentioned that the heat pump reached its target temperature at 1:30 a.m. today. After that, it still produced hot water. The heat pump just turned back on 15 minutes ago. Since the heat pump consumes 2 kWh, it’s easy to extrapolate until midnight. I assume the heat pump will run until midnight. That would be 6 hours of runtime over 24 hours. That means the heat pump uses 12 kWh, and the house consumption is 8 kWh. Otherwise, we usually have 10–12 kWh house consumption. Tomorrow definitely more because I have to charge the car.

How can the heat pump manage to reach the room temperature setpoint with 6kW output in 4 hours at these temperatures, especially since it gets even colder at night? I find that completely incomprehensible. Did you have a KfW 40+ house? It’s probably really extremely well insulated.

I already posted the screenshot of the data earlier. Yesterday, it also took exactly 5 hours and 14 minutes for the temperature to rise to 28.2°C (82.8°F), starting from 7:30 PM.

Yes, that’s clear, but it still isn’t good, right? It even exceeds my modest consumption...

I have no idea, I can’t assess that at all.

In the last 24 hours, 48.8 kWh of heat was generated for heating and hot water.
Outdoor temperatures ranged from 1°C to -13.2°C (34°F to 8°F), with an average temperature of -6.4°C (21°F).
Today, the house received a lot of solar heat from morning until evening.
