Is underfloor heating in the basement useful??

So I wouldn't want to miss the underfloor heating in my living basement and would definitely do it that way again …

Left out the laundry room and storage room …. I thought leaving out the laundry room was a mistake —> feet cold on the tiles …
So I would have to put on shoes if I want to hang up laundry ….

I would accept the extra cost in favor of
comfort.

We cannot decide between the standard radiators with 60 degrees supply temperature and underfloor heating with 30 degrees supply temperature in the basement.

The rest of the house has underfloor heating everywhere.

The developer recommended taking the radiators because the basement is well insulated anyway and, in his opinion, is heated sparsely.

We are connected to a local heating network and do not have our own heating system (which was mandatory).
If we had our own heating system, underfloor heating would definitely be better, but is that also the case with local heating?

What would you recommend for 2700€: choose underfloor heating or keep the standard radiators?

We use the basement as storage, laundry room, and gym (small home gym).

I have already written my recommendation above. May I ask what kind of [Nahwärme] this is? Where does it come from? What generates the energy there?

Underfloor heating is definitely more comfortable for the sports room and laundry room. For the storage room, it's not really necessary, but I wouldn't make an exception at that price!

I would take 30 degrees flow temperature as for the rest of the house and install a wall heating or the largest possible radiator on the wall. If the basement is within the thermal envelope like in our case: we hardly ever get below 18 °C down there even without heating, so only a small heating output is needed.

The plumber has to size for the worst case and always includes a margin. Take his objections into account and rather install the low heating output but with 30° flow temperature. Then the heating system is uniform and you could eventually switch simply to geothermal or air-to-water heat pump. Better to have than to need!

The local heating is generated by a combined heat and power plant (for 76 tenants)

We can also make the small storage room without underfloor heating so that there is no heating

The developer told us that the underfloor heating will have a room temperature controller that switches off automatically when the room temperature is reached
