Is an air source heat pump sufficient for a harsh winter in the Black Forest?

Tomtom, the heating element has nothing to do with the [Kontrollierte-Wohnraumlüftung]. At most, if the heat pump fails, you heat 100% with electricity...

With three months of use, the value is not meaningful.

I am not the only one who has an air-to-water heat pump, so users with more usage time will surely report as well.


I didn't say anything else. Only that in the event the heat pump fails, it still doesn't get cold in the apartment and that is positive.

Costs for electricity are at a special rate of 0.20 cents per kW.

You probably mean 0.20 €, right?

...then that (@@Cascada the heating and ventilation are theoretically separate, additionally if the Kontrollierte-Wohnraumlüftung should fail, an additional heating element kicks in.) was certainly just a mistake
To my knowledge, every heat pump has a heating element.

At -25 degrees, the coefficient of performance, if the device still works (!?), should be between 1.5 and 2.0 and the heat output of this heat pump should be around 2.0 to 2.5 kW. So it will have to be heavily supplemented with an electric heating element, because the heating demand will probably be considerably above the heating load calculation (which is based on standard outdoor temperature, which may be -16 or -18 degrees). Unfortunately, I have not found the information, does this heat pump have a built-in or retrofit electric heating element?
