ᐅ Natural gas heating system. Natural gas heat pump, micro combined heat and power unit?

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?

I can only comment on the approximate cost of the zeolite option. I was simply curious about the price of this new technology (Vaillant):
Heat pump approx. €12,000
Solar collectors approx. €2,000
Hot water storage tank approx. €1,000
+ small parts + installation + gas connection

I find this vastly overpriced compared to a "standard" heat pump.

Install the gas boiler yourself and calculate the house costs so that everything fits...

This is all just esotericism for eco-minded grain eaters wearing homemade sandals.

It doesn’t pay off, not even with subsidies, and if it doesn’t pay off, it’s not ecological either. These systems are so uneconomical because of the investment costs. Why is the investment so high? Energy, raw materials, and human resources!

In the end, you save a few hundred tons of CO2 but cause deforestation because the raw materials are mined in open-pit mines.

Get a proper gas boiler, solar water heating, and controlled mechanical ventilation with heat recovery, and the primary energy demand (qp) won’t be a problem.

That cannot be stated in general terms. Economics and ecology often have little in common; on the contrary, ecological solutions are frequently quite uneconomical.

There are really only a few positive opinions online about the heating systems mentioned by the original poster (for single-family houses). Costs are high, benefits limited.
