Construction costs are currently skyrocketing

The upper or lower half? ;-)

Of course the upper half. You want to swim, not dive. Maybe even increase the temperature at the top and then keep it only 10 degrees at the bottom. Put up a sign at the edge of the pool saying "Mixing water forbidden!" :p

With us, the pools have taken very different measures

Kisssalis with almost no restrictions and heated as always via shortened opening hours up to the Triamare, which has adjusted everything everywhere.

It is just a question of how long a business can operate with deficits.

Our indoor pool was instructed to lower the water temperature, supposedly to 27 degrees (which is certainly not true) and to close the sauna entirely. Not for cost reasons, but to contribute to energy saving.

Such instructions are probably only feasible for municipal enterprises. I do not think it is possible for private companies.

Sorry, I was short with people all day today...

~160 sqm according to KFW55, we have central ventilation from Zehnder...

The heating engineer said, if I understood him correctly, 6000 kWh electricity for heating + domestic hot water... That would probably be around 18,000 kWh of heat...

The local heating (biogas waste heat) costs 9 cents/kWh until 2031 + €416 basic charge... The operator is a private cooperative... so maximally profit-oriented.

I really find that a lot for the house. Then it costs a slim €3,000 per year at 50 cents per kWh. District heating would be €2,000 per year.
