ᐅ Attic Prepared for Conversion – Which Heating System to Choose?

Hello,

we are a family of four and have decided to buy a solid end-terrace house. Underfloor heating will be installed throughout the entire ground floor (except for the utility room) and first floor.
The heat generation will be provided by an air-to-water heat pump.

We have decided to have the attic prepared for finishing, which means a second spiral staircase, an upper hallway, and a door will be installed.

Two low-temperature radiators will be installed in the attic.

Intended use of the attic:
About 50% storage (due to the lack of a basement) and about 50% an occasionally used guest/hobby room.

Does it make sense to also install underfloor heating in the attic?
Personally, I am a bit reluctant. Underfloor heating responds quite slowly, so running it continuously in the attic seems questionable in terms of energy efficiency.

Are these low-temperature radiators suitable to heat the room quickly enough with the low supply temperature of the heat pump (around 35°C (95°F))?

Best regards from Berlin

It will be the same for us. According to our heating specialists, we should definitely make sure that the low-temperature radiators are quite large and preferably equipped with convection (i.e., a fan).
