Good morning,
I just received a steep price increase from my energy provider enercity, raising the cost to 15 cents per kWh starting in August. That’s really tough, and I think prices will rise even further.
It’s a strange feeling to be thrown back so quickly into an energy supply situation where you have to figure out how to keep the house warm. It seems to me that the government has given up on the goal of enabling everyone to adequately cover at least their basic needs.
Goodbye central supply structures; now the winner is whoever has solar panels and a heat pump in their new build, while the others are left out.
Welcome back, coal heating 😕
Frustrated regards,

If you use cheap, fossil gas from Russia, then yes.
Otherwise not. Nonsense, what does the origin of the gas have to do with it?
Even though you write it’s physically very simple, you seem to lack basic knowledge.
Here are the numbers:
Burning gas for heat: 100% efficiency
Gas power plant + heat pump: 40% * 500% = 200%

Even though you say it’s physically quite simple, it seems you lack basic knowledge.
Here are the numbers:
Burning gas for heat: 100% efficiency
Gas power plant + heat pump: 40% * 500% = 200% With this simplistic calculation, you seriously dare to question others’ basic understanding of physics?
Sorry, but how long did you study physics? Up to grade 9?
PS:
Economic efficiency is not just physics. It also involves the ratio of gas prices to electricity prices and, of course, the additional costs of the heat pump...
But business studies probably weren’t part of your curriculum up to grade 9 either 😉

A few years ago, I discussed this with some university researchers... it's not that simple with fuel cells, they are quite "picky," don’t like sudden load changes, and so on.I know, but even here everything is constantly evolving.
The best approach is to use hydrogen to power the compressor of a heat pump — via an internal combustion engine. This way, you get heat immediately and can also preheat the air if needed.

The best approach might be to power the compressor of a heat pump with hydrogen – using an internal combustion engine. That way, you get the heat directly and can also preheat the air if needed. With all the enthusiasm, one must never forget:
The more and the more complex technology you use, the more and the more expensive it can fail...
If such a system doesn’t last at least until it reaches break-even, in the end, you haven’t saved a single cent...

I wouldn’t say refrigerators and combustion engines are still cutting-edge. 😉It’s less about being cutting-edge and more about the number of components and assemblies involved...
The probability of a failure doesn’t increase linearly with the number of parts but rather exponentially...
Now let’s consider where more assemblies and parts are involved.
In a gas boiler... or in a heat pump system with a ground-source heat exchanger / air radiator, photovoltaic panels, and a compressor driven by a combustion engine...
