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

We are still quite a way from that. However, we are slowly approaching the transitional period when shading is no longer necessary, allowing the sun to control the temperature.

How cold is it over there where you are?

10 to 16 degrees Celsius (50 to 61 degrees Fahrenheit). For me, it’s a mix of desired warm indoor temperatures, rather little sunshine two days ago, lots of wind, and a plot that didn’t allow for a true south-facing orientation of the house. The KfW 55 energy standard was only just met. So, I start heating a bit earlier than others.

When you compare the heating costs to other expenses, they are quite manageable. The heating technician actually wants 400 euros per year for a maintenance contract (heat pump, hot water tank, controlled ventilation system). It seems unnecessary and like a pure rip-off, but I might have no choice because of the warranty...

The same weather as here. Max. 1-2 hours of sun per day, otherwise just rain for days.
So far, the little sun together with cooking, showering, etc. is enough to keep the temperature at 21-23 degrees Celsius (70-73 degrees Fahrenheit). But we’re all home all day right now as well.

Luckily, there’s sun again starting Wednesday. In August, I wouldn’t have heated on principle 😉

Same with Stiebel Eltron. Luckily, we don’t have to bite the bullet for long.

Current average temperature is 10.6°C (51°F), but the heating stayed off last night. Indoor temperature is between 22.5 and 23.3°C (72.5 and 74°F). The heating system is set to automatic, with a heating limit set at 14°C (57°F).

Our home is always pleasantly warm.

What is this "sun"???

That bright thing behind the roller shutter. Nobody needs it.
