ᐅ Underfloor heating / radiant floor heating

Hi everyone,

First of all, many thanks for all the helpful contributions.

I have two questions regarding underfloor heating:

First: Among the quotes I received, some providers use pure plastic pipes, while others use aluminum composite pipes. Could you tell me which option is more practical?

Second: Regarding plastic pipes, there are now oval-shaped versions that are said to significantly reduce the boiler’s operating temperature. Can someone who has the oval pipes confirm or refute this? After all, the oval pipes are considerably more expensive than the conventional ones.

Thanks a lot for your answers.

Best regards, Jean

Both are suitable, provided oxygen tightness is guaranteed and there is an approval (certification).

I would like to see proof of that 😉 There is a lot marketed with patents claimed. If you take a closer look, most of it turns out to be empty claims. From a flow dynamics perspective, an oval cross-section is always a disadvantage. Also, these pipes tend to kink more easily during installation!

An accurate dimensioning is crucial for underfloor heating! Many mistakes are often made here that are difficult to correct afterwards.
