Underfloor Heating Pressure Rising

by robby2023 » Mon Jun 26, 2023 9:47 am

Hello,

We have had wet underfloor heating installed beneath our slab. At the time of installation the circuit was filled and was holding pressure. The circuit is still just connected to the manifold and no further. In the warmer weather, I have noticed that the pressure is increasing up to about 6 bar on occasions. It decreases overnight and increases during the day. I can't think what may be causing such a large increase because there isn't much under the floor other than the pipework. I am concerned about what will happen when the heat is applied in the colder months.

Thanks,

Rob
