Underfloor heating or not?

We are still considering what we should actually choose. It is clear to us that underfloor heating will be installed throughout the entire ground floor (living room, kitchen, hallway, utility room, guest bathroom, and storage). On the upper floor, additionally the master bathroom and the guest/office room. We are seriously thinking about radiators in the two children's rooms and in the bedroom. Simply to be able to adjust the temperature more quickly there if needed.

I understand the reasons very well, but I wonder how that is supposed to work effectively. As a layperson in technical matters, I would say that the "normal" heating operates with a higher flow temperature, that is, when conventional convectors are used. In underfloor heating, the flow temperature is significantly lower. If you have both systems, then there should actually be two "heatings," right, or am I on the wrong track? Doesn’t that definitely cost "much" more money than if you install underfloor heating everywhere?

You need two heating circuits, right.

There are also huge [HK] with correspondingly large areas, which are designed for very low supply temperatures.

Hello Yvonne,

That is not true. Every builder who wants to run both classic radiators and underfloor heating needs one mixing valve (I don't remember exactly what the part is called); nothing more. Alternatively, it can be done without a "mixing valve," but then the radiators have to be correspondingly much larger.

Hello Yvonne,


That’s not true. Every builder who wants to run both classic radiators and underfloor heating needs a mixer (I don’t remember exactly what the thing is called); nothing more. Alternatively, it’s also possible without a "mixer", but then the radiators have to be correspondingly much larger.

Thanks for the info :) I thought I had read it differently once...
