Gas price increase as of 1.1.2022

Are there statistics on how much more efficient a ground-source heat pump is compared to an air-source heat pump? We are having a ground-source heat pump installed but with surface collectors (water protection area).

It doesn't make much difference, for example: if you assume a heat demand of 10,000 kWh, you end up with an annual performance factor of 4 (air-source heat pump) at 2,500 kWh electricity, and with an annual performance factor of 5 (ground-source heat pump) at 2,000 kWh. Difference 500 kWh or about 120-150€. Depending on photovoltaic self-sufficiency, even less. Even our very dedicated energy consultant called our ground-source heat pump "a hobby" :) The big advantage of the ground-source heat pump is that it can operate without an electric heating element even at severe subzero temperatures.

Kann man gut auf den Umweltschutz umschreiben...

I find it an outrageous tastelessness to compare the Holocaust with man-made climate change.

You probably didn’t read/understand the content. It’s about the core. If everyone looks away, soon there will be no one left who can do it.

I did expect a comment like that...

Don't let it upset you, nowadays people really look everywhere for things to get outraged about.

The comparison is stupid, tasteless, and simply wrong. Heating choice and mass murder are two completely different universes. By the way, I heat with oil and am very happy with it.

Rarely read a more idiotic comment...
