In screed hydronic underfloor heating is a very effective option for large homes. This type of hydronic heating is more cost-efficient and far more flexible than conventional heating systems for large spaces.

In screed heating uses a wide range of heat sources and can be safely used on any type of floor, including polished concrete. These hydronic systems are an excellent solution for homes with heating problems in winter or commercial spaces that need reliable seasonal heating.


Hydronic in screed heating is suitable for large areas (80 m² +) and can be used in a variety of installations where a sand and cement bed is being used. The minimum depth of the screed bed is 50mm. In screed installations have a faster response time than in slab installations, as it is closer to the floor surface.

Pipe Technology

REHAU PEX pipe is specifically used for under floor heating. It is a cross-linked polyethylene pipe with an oxygen barrier to prevent corrosion.

Heat Output

With in-screed hydronic heating, we aim for a heat output of around 100-120W/m². A combination of flow and temperature is balanced to suit the heat load requirement of each room.


The hydronic floor heating pipe is installed on top of the subfloor, before the cement screed and beneath any type of floor covering (generally tile). You must cover the cable with a minimum of 50mm bed of screed.

The hydronic floor heating pipe is held on the floor by either plastic pins attached to 30mm insulation foam (R1 rating) or clipped to a light wire mesh. (An additional reinforcing mesh will need to be installed in the screed)
