that is ridiculous compared to the increase in electricity consumption! the heat pumps will still cost us a lot of money to operate thanks to this incompetent government. And the Greens will increase everything even further, they and their voters themselves have the financial means to afford almost everything. Oh dear, I'm just whining...

Sometimes I agree with bookstar. This whole gang from Merkel to Borjans and Bärbock must be voted out.

You wrote you have a gas heating system and additionally a heat pump for cooling; did I misread something there?

And the Renewable Energy Act surcharge is supposed to be eliminated. So 2:0 for the heat pump

Electricity is already 100% CO2-free according to the government, see fleet limit for electric cars...

Soon the fleet limit for heating systems will come

As I said, it is 35% additional costs, not "6.5 instead of 5 cents."
Sure, in new buildings that's not a huge amount of money, from 60€ gas then becomes 80€ per month.
But for Grandma Hilde in an old building, 150€ then becomes 200€.
The H4 recipient in a cheap old building forwards that to the office, by the way.



Maybe some things aren't fast enough. After all, you also want to be re-elected.
But you can't say that nothing is happening. Heat pump technology has been heavily subsidized for years, either directly through BAFA or indirectly through KFW programs, where from KFW 55 onwards, there is basically no way around the heat pump. The primary energy factor was reduced to favor heat pumps over gas, etc.

You can't just double all prices overnight or ban them as scrap metal.
I find a 35% price increase for gas over 6 years already comparatively significant. The Renewable Energy Act surcharge is supposed to be reduced in return, currently 6 cents or 20% of electricity costs.
That shifts the balance between heat pumps and gas even more clearly towards heat pumps.

So 60€ gas becomes 80€ gas and 50€ electricity becomes 40€ electricity per month.
What before still felt close together, and could be dismissed with "oh only 10€," then clearly means: gas costs twice as much in consumption.
That might not be noticeable today, but definitely in 6-7 years.

If it is implemented that way.

I am currently paying 5 cents, in 2026 that would be 6.6 cents.

That is 32% more than now for me.

Electricity will not get cheaper, that is clear.

Normal electricity has meanwhile reached about ~33 cents here.
