ᐅ New Single-Family Home Construction – Gas or Air Source Heat Pump + Photovoltaic System + Energy Storage?

And by the way, another gas pipeline is being built to and through Germany… So much for the claim that no gas infrastructure is being constructed in 2021… pfff.

Sounds strange, but it's true… (from the mouse, five words and so on)

One thing is corruption and the wanton destruction of our only habitat. The other is what a reasonable person should do. Unless you have no children and don’t care about anything. But even then, you should have enough pumps in the basement.

Half of Europe is flooding, while at the other end, forests are burning again. How ignorant can you be to still use gas in a NEW BUILD in 2021?! Feel free to ask the politicians who allow this to be installed in a new housing development!

According to calculations, the CO2 tax on gas is expected to be around €120 per 10,000 kWh (34,000,000 Btu) of heating demand starting in 2025. Electricity costs for heat pumps have also steadily increased in recent years (currently about 20 cents per kWh). This remains an important factor to consider and should be included in the calculations.

I need to jump back into this discussion. We ruled out an air-to-water heat pump because an outdoor unit is not an option for us. A compact unit with only an indoor component is also not suitable (it takes up too much space and can be noisy in winter).

The remaining options are gas or a geothermal heat pump. A geothermal heat pump (deep drilling) is said to be much more efficient than an air-to-water heat pump and would be permitted for us. However, the additional cost compared to gas is quite significant. You start wondering when you’ll recover that difference compared to gas. For now, we’re planning without solar panels / photovoltaics. It’s just that nowadays, people tend to feel guilty building with gas (it’s a shame how much opinions have changed over the last few years). We initially planned for gas, but due to all the negative sentiment, we will now plan for a geothermal heat pump.

Nobody builds with gas anymore in 2021. In the countries around us, it is currently being banned, and we won’t be able to avoid this for much longer either. So if you want to “have peace and quiet,” you definitely shouldn’t include gas in new construction.
Oh, and of course, for the last 20 years, solar thermal systems have not been installed on roofs, but photovoltaic panels instead, because only the latter generate income.

And why exactly should I base my decisions on what "ONE" supposedly does or doesn’t do...?
