Hello there.
We want to renovate our outbuilding and install underfloor heating. Now we have a problem with the ceiling height. It is currently 190cm (75 inches). The underfloor heating system has a total height of 25cm (10 inches). The heating installer said we need to lower the floor by 35cm (14 inches) compared to its current level to have a reasonable ceiling height. The existing base is a concrete slab. Now the question is, how do we level the slab again after cutting or removing 35cm (14 inches) from it? Or can someone explain the typical floor structure up to the underfloor heating?
Have a nice Sunday everyone.

There are also retrofit systems for underfloor heating that require only a few centimeters (inches) of installation height.However, it is problematic if the heat from the underfloor heating is lost deep into the more or less uninsulated floor slab.

Also, 35cm (14 inches) is probably more than the entire thickness of your slab. With professional help, it’s also an expensive undertaking.
Check out the Actifloor website. That might be something to consider.

Take a look at the Actifloor website. That might be an option.Hello and thank you.One issue is the underfloor heating and the other is the insulation underneath. Even if we were to omit the underfloor heating, we would still need to insulate the floor, and then the build-up would be too high—or would it be no problem to remove 10cm (4 inches) from the floor?
