Construction costs are currently skyrocketing

Friends of mine lived in an apartment (rented) without heating. There was only an electric heater in the bathroom. The end result was electric fan heaters in every room. It was kind of uncomfortable...

Blowers are the most uncomfortable thing you can have. But at least the rent reduction for an apartment without heating should have compensated the electricity costs.

Gas currently costs me 10.38 cents/kWh, heating electricity would be 25.11 cents/kWh. The gas boiler maintenance costs 200 EUR, about the same as the heat pump inspection plus the meter for the heating electricity, however you set it up.
The builder wanted a surcharge of 12,000 EUR for the heat pump compared to gas. If I assume an unrealistic annual performance factor of 4 for the air-to-water heat pump and need 10,000 kWh of heat, I come to a saving of 410 EUR per year.

29.3 years before it pays off.

And no, photovoltaics is also not a solution, because you first have to have and invest the 10,000 EUR for the system on the roof...

Great for the green conscience and at the tea party in the eco-shop... economically pure nonsense ;)

I would assume that if there are enough heat pumps, then a duty of inspection by the chimney sweep of any kind would be introduced.

My WP was subsidized by BAFA at 45%. Of the 12000€, I got about 5500€ back. What does a gas heating system cost?
A gas connection was not available at our property; the previous owner had an oil heating system with tanks in the basement.
Offer for gas connection (municipal provider) around 5000€. And voilà... the issue paid for itself after the first day of operation.

It's just darling that when it comes to "Gas vs. Heat Pump" it's always only about the money. How thermally nonsensical an open flame is, simply doesn't matter - people just take whatever is cheaper.

That's why I stick to my point: People will only become sensible when the kWh costs 30 euros, no matter the energy source. All these stories here like: I turn the heating up to maximum and if it's too warm, then I open the window. As long as things like that still happen, energy is way too cheap.

I once searched in my emails... Price from autumn 2020 at Town & Country in Singen (KN). Furthermore, the chimney and the obviously builder-provided gas connection are omitted. Overall, the costs would have been almost neutral. So you have to recalculate your calculation. Must is a good keyword anyway, because the question of photovoltaics no longer arises here. It has to be installed; otherwise, at some point, a nasty letter will come from the authorities. And with that, you will have already heated quite cheaply during the transition period. Of course, there are other suppliers who wanted to sell us the BAFA-eligible monster units with integrated controlled residential ventilation for just under 40k.
