Underfloor heating or not?

First of all, thank you very much for the previous entries. As a result, it must be said that this has led to the offer a) being reduced by EUR 1,000 and b) the utility room now being equipped with underfloor heating at this price. Basically, I mainly have you to thank for this. Thank you very much for that. We will choose the underfloor heating.

Hello Yvonne,


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

Just a quick follow-up question. Is it to be understood that the radiator rooms require a higher supply temperature for all rooms (and thus higher energy costs) and this "mixer" reduces the temperature for the underfloor heating rooms?

A heating engineer could certainly phrase this better, but since I am not one, I just want to simply agree.

Your description makes it clear that it is uneconomical to accept this energetic nonsense for one or, for that matter, even two radiators; better to have larger panel radiators instead. However, there are now systems that accommodate this "new" desire of homeowners to combine radiators and underfloor heating. => heat distribution system in which underfloor heating and radiators are operated with the same flow temperature (up to max. 70 °C in the design case) without exceeding the permissible surface temperatures on the floor.

Now please don’t ask me exactly how it works – it apparently has something to do with an air gap in the pipe to be laid – as I said, I am currently not a heating technician; the main thing is that our contractor knows this, if this system is desired ;)
