KfW 55 without underfloor heating

To connect to the thoughts of ypg. I'm just wondering if that's technically even feasible? KFW55 somehow strongly sounds like a heat pump. Can you even get the necessary supply temperature for classic heating from those? I had always assumed that you have to see the energy source and the radiator (for example heat pump and underfloor heating) as a system...?!

Yes, you get it, the cop is then of course significantly worse.

Ahh, ok. Learned something new again, thank you [emoji1303] I always thought that with a traditional heating system you would fail due to the requirements of the Energy Saving Ordinance... but I was apparently wrong [emoji4]

With enough resources, you can still accomplish quite a bit... the only question is, why?

Technically feasible.

No, we are getting a completely normal gas boiler.

What was important was whether the KFW 55 standard is achieved despite the radiators. This has now been confirmed.

While we would save about 12% more on heating costs with the underfloor heating, it is not worth the additional costs.

For us personally, the underfloor heating has more disadvantages than advantages, also health-wise.

Still, thank you for your opinions.

For us, it's now going to the architect.
