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

Currently, my total electricity consumption with photovoltaic support is about 9-13 kWh per day.

My average before this week was 16 kWh per day since mid-October, which I find quite high considering the temperatures.

I think it’s simply colder here, with nighttime temperatures still around -4°C (25°F), so the house loses a lot of heat. That’s why I’m adjusting the heating curve now; a parallel shift keeps triggering the faulty device for me, and I don’t know why.

I generally operate about 20% above the heat demand level I would normally consider typical. I haven’t been able to determine the cause so far. The heat pump’s efficiency seems to be fine.

I don’t think that’s too far off. February will probably end up around 700 kWh overall, which is actually quite good. It was really freezing this year—on average about 3°C (5°F) colder than last year! So it’s still pretty cold. But surely it could be a few kWh less 🙂. For hot water, we use about 3-4 kWh of electricity per day on average, even during summer. That leaves around 15 kWh currently for heating. Given the cold nights, that’s somewhat understandable.

Since we will soon have two electric cars and next week we’re also adding a sauna, I will definitely put photovoltaics on the list for 2022 🙂

Are you referring to 700 kWh for heating and the heat pump? But well, you have to be satisfied, and it seems you are.

Here, the total household consumption for February is currently 347 kWh from the grid. But that’s because I only used 12 kWh in the last eight days.

P.S. I can already picture you charging your electric cars at night despite having photovoltaics 😎

Yes, 700 for heating and hot water in February. As I said, it was freezing cold, so that’s understandable.

I’m satisfied as long as my monthly heating costs don’t average more than 80 euros for the house. That’s what I had always budgeted. Last year I managed that well, but this year it was extremely cold, so it might be close to my target 😀.

Back then, I considered geothermal heating, but even after subsidies, it would have cost me an additional 12,000 euros. Now, if I calculate that my heating costs would be about 60 euros per month with that system, it would take roughly 50 years to break even. So it’s pretty comfortable living with the air-source heat pump!

Currently, the average energy consumption in February is 33 kWh for heating, hot water, and household electricity.

Just had an idea. Throughout November, we had the same average temperature as the last 4 days in February. When converted for November, I come to 19 kWh per day. That is exactly the same as the last 3 days.

This means the heating system runs just as well/poorly without control as it did in November 😀...
