Hello
We are planning to build a single-family house in the near future. Since we are still at the very beginning and currently looking for a plot of land, this near future will probably start around 2016/2017. Until then, I am reviewing concepts and designing the home. As the Energy Saving Ordinance 2016 will be tightened again 😱, questions about heating arise. Since I absolutely and non-negotiably 😎 want a gas stove and a heating fireplace, it will probably come down to a gas heating system. The chimney has to be built anyway, so why not a double-flue one. And since a gas connection is necessary for the gas stove, you can also operate a gas heating system directly. And no, a gas stove with a bottle is not an alternative. 🙄
So, the Energy Saving Ordinance is becoming stricter, which makes installing a gas condensing boiler more difficult. Alternatives? Ideas? Experiences? 🙂
Who among you uses a natural gas heat pump? Depending on the type, gas engine heat pump, zeolite heat pump?
Who has a micro combined heat and power unit? Conventional or Stirling engine?
Can you share your experiences and investment costs?

Over 20 years ago, a colleague of my father installed a combined heat and power unit in his basement.
He also wanted to be electrically self-sufficient, with storage and so on.
The system never worked properly; its efficiency was terrible, and there were frequent power outages.
After 2 to 3 years, he got rid of it, had a proper electrical connection installed, and switched to a conventional heating system.
I would be interested to see the environmental impact of that entire process.
Sure, the technology has advanced over the past 20 years, but still, I wouldn’t want to be an early adopter.

This makes it even more expensive.

On the contrary, ecological options are often very uneconomical.

The chimney needs to be built anyway, so why not make it double-flue. I can’t contribute much about the rest, but usually a flue pipe is installed somewhere for a gas boiler, which takes up significantly less space than a second chimney flue.

Would nuclear power be economical if the cost of a waste repository (10,000 years) were factored into today’s price (discounted)? Probably not…You can try discounting the costs yourself.
If energy companies invest just one million euros at 3%, in 500 years they would have saved enough money to buy all of Europe. The storage of nuclear waste could then be paid for out of pocket, if it is still necessary at all.
If you discount 10,000 years, it would probably only take around 15 euros to cover the waste repository costs. Just as an example. 😀
