Wet underfloor heating doesn't work in summer?????

[Frau Vicky]

Dear all,

We have recently moved into a new flat with wet underfloor heating and we turned it on Saturday for the first time. After 24 hours we had an ambient heat in the flat, but the floor was cool except in the areas where the pipes run together. The man who did the installation said that this is normal when the outside temperature is above 0°c and we would have warm floors in winter as that would make the heating work harder (this is a rough translation of Berliner German and really against the upper limits of my language abilities since I know nothing about plumbing in any language). But this seems nonsensical to me; surely, if you run hot water through anything it should get warm notwithstanding the weather. I would like to go back armed with the collective wisdom of the Plumers Forum UK, and am grateful in advance for your responses.

Hi Vicky, welcome to the forum. The underfloor heating will have an outside sensor and the temperature of the water that flows through the pipework is dependent on this reading. So the colder it gets outside the warmer the water flows through the underfloor pipework and the warmer the floor will feel.

Google translate to German,
Hallo Vicky, dem Forum begrüßen zu dürfen. Die Fußbodenheizung wird eineAußentemperaturfühler und die Temperatur des Wassers, das durch die Rohrleitungfließt, ist abhängig von dieser Lesung. Also desto kälter wird es außerhalb Je wärmer das Wasser fließt durch die Unterflur-Leitungen und je wärmer der Boden fühlen.

A good explanation in any language.

Ps. I swear by the Babel Fish stuck in my ear.
