Old building apartment with gas boiler - underfloor heating now, heat pump later

Irrelevant for new construction, but maybe interesting for old building renovation? As far as I know, the supply temperature is at least somewhat lower than traditional radiators. But thanks for the feedback. I am just looking for alternatives to underfloor heating.

There are also low-temperature radiators, which are not underfloor heating either, but better than grandma’s radiator.

I would rather install 33-type radiators, which then tolerate significantly lower supply temperatures (provided there is enough space).

Because if you "only" replace baseboard heating with old radiators, you're throwing money away without added value. Whether you have €64 monthly or €66.34 monthly heating costs in the end doesn’t matter. The investment will never pay off.

My opinion.
