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

The heating turned on again last night, and looking at the temperatures over the next few days, it seems like the heating will come on every night. I need to call my electricity provider now and increase the advance payment, otherwise the final bill this year will be too high.

The weather this year is absolutely crazy—so much for climate change....

Then I shouldn’t mention that June looks almost as bad as May in the 42-day weather forecast.

Good thing you’re planning to install a photovoltaic system.

Do you get a lot of wind there? Even with so much cloud cover, the temperature stayed pretty steady here.

The house is located quite openly on a hill, with few buildings around. So yes, there is a lot of wind. The problem is you might not notice it for 1-2 days, but it’s continuously freezing cold. The weather is annoying either way 🙂.

Or your air-filled premium bricks have a slightly worse U-value than the idealized one stated in the datasheet.

That is certainly the case. It’s the same with everything. You just get cheated everywhere.

This is really unusual for this time of year. The heating is running every day, and it’s already the end of May.

What temperatures are you seeing? Currently, I’m running a supply temperature of 29.5°C (85°F) and a return target of 25.4°C (78°F). The outside temperature is 8°C (46°F). This results in about 22.5°C (73°F) inside the house.

I somehow feel the supply temperature is a bit too high. I would have expected something more like 27 to 28°C (81 to 82°F).

So, a 4K temperature difference is definitely a good thing! It transfers heat energy to the room effectively.

Apart from the fact that you apparently live on the Zugspitze, I’m starting to get the feeling that you might have a significant issue with thermal bridges. The energy has to be going somewhere. Strange. Or are the windows possibly left tilted open continuously or something like that?
Our heating has been off for a while now, as discussed before. When I was recording the monthly consumption data, I noticed that in 2020 the heating turned off noticeably earlier—around March/April it was still on but the consumption was minimal. April 2021 used three times more heating energy than April 2020. You could call that weather 🙂
