Electricity and Gas Brake - Interested in some numbers?

But please with two times two weeks of proper frost from January to February, so that more mosquitoes die.

Yes, that is an important point - we urgently need the frost for the environment (many plants, including food, animals) nonetheless. My comment was only related to the economy and a possible gas shortage. Personally, I love snow and frost, and as far as I'm concerned, there can be a continuous snow cover from December to February^^.

I hate snow and cold (at least in the city). I’d rather stay in the mountains.

But I hate mosquitoes much more. Otherwise, I would have long ago emigrated to Thailand or something.

It doesn't have to make sense everything we do here in the forum, sometimes you can do something just for fun!!! :) :) :)

You're not doing it for the forum, but because you think you can get some clarity in a comparison. And let me tell you: that just doesn't work with apples and pears ;)

The heat pump might be ahead with an annual performance factor of 4, which is hardly achievable with an air-to-air heat pump. Most are around 3-3.5.

Electricity should therefore cost around 42 cents at 12 cents for gas.
If you get the heat pump for free, because the extra costs over a gas heating system are about 12,000 EUR. If you want to achieve an annual performance factor of 4, even significantly more, because the underfloor heating has to be optimized for low supply temperature. So more piping, closer spacing, more heating circuits, more controls, more work...

A floor heating system optimized for 28°C supply temperature with an air-to-water heat pump would therefore cost 15-20,000 EUR more than a gas heating system.

You won't make that back even in 30 years. By then the heat pump will be broken anyway and you'll need another one...

If we then talk about geothermal with an annual performance factor of 5, which requires a deep borehole for 20,000 EUR... no thanks ;)

PS:
15,000 at the current 4% interest rate, by the way.

Oh... anyone who thinks electricity will get cheaper, considering all that we will have to invest in grids, storage, expansion, etc. in the coming years. Unfortunately, that person does not have a realistic view. At the moment, solar expansion is mainly being carried out by private builders at their own expense. But the electricity has to be stored in the summer... the electric car is not sufficient for that.
