ᐅ Vinyl click-lock or glue-down option?

Hello.
Both options, glued vinyl flooring and floating vinyl flooring (click vinyl), are recommended for new builds. Even though a small air gap forms with click vinyl, heat can still be transferred very effectively to the vinyl floor. There is only a slight delay in energy transfer (of a few minutes).

With the glued option, there is no air gap between the screed and the vinyl floor, so heat is transferred immediately to the vinyl.

You can install either option, as they provide the same level of heat transfer.

Delay means loss. A vacuum flask only delays as well. If you want to use it for heating, you need significantly higher temperatures, which reduces efficiency.

No, it doesn’t. Where exactly would the energy be lost? Energy doesn’t just disappear. Even I know that from basic physics.

Modern underfloor heating systems operate at such low temperatures that if you don’t adjust the thermostat every hour, it doesn’t really matter.

If I insulate 12cm (5 inches) above the pipes and 12cm (5 inches) below, half of the heat will go into the ground (very simplified...) – that’s the answer to the question of where the heat goes. However, I would also assume that both methods work and the heat loss is rather minimal.

A modern underfloor heating system operates at such low temperatures that, unless you’re constantly adjusting the thermostat every hour, it’s not really significant.

Think about a thermos flask. The energy doesn’t just vanish, but it also doesn’t enter your room—or only very slowly. To reach the same room temperature, you therefore need to set a higher flow temperature.

However, in practice, the difference between sticking and not sticking probably isn’t that big.

Thank you!
"Floating installation" and "click" mean the same thing, right? I somehow always associate the first term with moisture...
