Screed hydronic underfloor heatingĀ is ideal for large homes. This type of hydronic heating is very cost-efficient and far more flexible than conventional heating systems for large spaces.

Screed heating uses a wide range of heat sources and can have any floor covering on top, including polished concrete.

Technical Data

Pipe Type: Cross-linked polyethylene pipe with oxygen barrier

Pipe Diameter: 16mm

Screed Thickness: Minimum 50mm

Pipe Warranty: 25 years

APPLICATIONS

Hydronic in-screed heating is suitable for large areas (80 m²+) and requires a sand and cement bed on top of the pipe. The minimum depth of the screed bed is 50mm. In-screed installations have a faster response time than in slab installations, as the pipe is closer to the floor surface.

PIPE TECHNOLOGY

REHAU PEX pipe is specifically used for underfloor 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 100-120W/m². A combination of flow and temperature is balanced to suit the heat load requirement of each area.

Installation

Hydronic floor heating pipe is installed on top of the subfloor, before the cement screed, and beneath any type of floor covering. 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)
