Lets Talk Underfloor Heating
Posted on September 14, 2015
It was in the mid-1980s that underfloor heating became popular. The basic idea to conduct heat under the floor dates all the way back to the Roman times but it has happened a lot since then to say the least.
Nowadays one can say that there are two methods of casting the heating coils in the base plate or to put them on top. But which method is best is difficult to determine.
When building a new house with concrete slab floor and select cast the heating coils are usually put inside in the concrete. The insulation under the concrete is normally between 200-300 millimeters.
There is also a system in which heating elements are added on top of the concrete slab.
The actual construction is not new, it is sometimes called floating floor and is used mainly in apartment buildings with concrete slab and the existing house where you want to have underfloor heating.
The principle of the floating floor is that you put a tracked foam disc on the concrete slab. The tracks are then heat-pipes. The disc is available in various thicknesses, depending on how well the base is isolated. As a heat-diffuser between the pipe and the floor is an aluminum plate.
Cellular plastics have high compressive strength and can handle a thin floor covering, such as parquet or laminate. If you want to have vinyl flooring or tiles you must add chipboard and plasterboard between the foam and the floor.
If you choose a wooden floor the temperature should not exceed 80.6 degrees.
