Natural gas-powered heating. Natural gas WP, micro combined heat and power plant?

Hello

We are planning to build a single-family house in the near future. Since we are still at the very beginning and are still looking for a plot of land, this near future will probably start rather in 2016/2017. Until then, I am looking at concepts and planning the home. Since the Energy Saving Ordinance 2016 is tightened again :eek:, questions arise about heating. Since I absolutely and unequivocally :cool: 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. And since a gas connection is necessary for the gas stove, you can directly operate a gas heating system. And no, a gas stove with a bottle is not an alternative. :rolleyes:

So the Energy Saving Ordinance is tightened and makes the installation of 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 uses a micro combined heat and power plant? Conventional or Stirling engine?

Can you share your experiences and investment costs with it?

Can only say something about the approximate price of the zeolite variant. I was simply interested in what this new technology costs (Vaillant): Heat pump approx. €12,000 Solar collectors approx. €2,000 Hot water tank approx. €1,000 + small parts + installation + gas connection I find it outrageously overpriced compared to a "normal" heat pump.

Install the gas boiler and have the house calculated so that it fits...

That's all esotericism for ecologically minded grain destroyers wearing Bastlatschen.

The stuff doesn't pay off, not even with the subsidies, and what doesn't pay off isn't ecological either. The things are so uneconomical because of the investment. Why is the investment so high? Energy, raw materials, and human resources!
In the end, you save a few hundred tons of CO2, but you've cut down rainforest because the raw materials are mined in open-pit mining...

Get a proper gas boiler, solar domestic water heating, and controlled residential ventilation with energy recovery, and the qp is no problem.

That cannot be said in general. Economy and ecology often have nothing in common down to many letters; on the contrary, ecology is often very uneconomical.

Positive opinions about the heating systems mentioned by the TE are really few on the internet (for single-family houses). Costs are high, benefits are limited.
