Construction costs are currently skyrocketing

Well, it doesn't look that different at the Federal Environment Agency either.

Well, it doesn’t look much different at the Umweltbundesamt either.

I’m missing fracked and US LNG exported to DE in the graphic.
I mean that seriously – where do we stand in this case?

Look at the bottom right of the graphic.
A knave who thinks evil of it.

Whereas modern pellet heating systems or condensing boilers aren’t really that bad and have nothing to do with a classic stove. But the CO2 emissions of the heat pump are quite amusing.

Is the fine dust from the heat pump basically calculated from the electricity mix? Otherwise, it can’t be explained, or am I missing something?

Is the fine dust with the heat pump then basically calculated from the electricity mix? Otherwise, it can't be explained, or am I missing something?

That is probably from the electricity mix. If you take "green electricity," it looks different.
It is also unclear whether it is about primary energy or the generated heat energy. If the former, the COP is missing in the calculation for the heat pump.

That will probably come from the electricity mix. If you take "green electricity," it looks different.

And, where does the green electricity come from when the heat pump is preferably in operation, that is from November to March?! Hardly from solar, and the wind doesn't always blow either. If you order green electricity, the provider only has to have bought it in the annual balance overall, meaning: in winter, they also buy a lot of coal and gas electricity. Of course, because what doesn't exist, they can hardly sell!

It is also unclear whether it concerns primary energy or the generated heat energy. If the former, then the COP of the heat pump is missing in the calculation.

Based on 1 kWh of supplied heat energy.

The advantage of the heat pump is that any improvement in the electricity mix automatically applies to all end devices without having to replace them. The same applies to the car. And since both tend to be durable goods, that is also a factor not to be underestimated.
