Water underfloor heating is durable and reliable

Water Underfloor Heating Under Concrete/Screed

Installing water underfloor heating under new concrete or screed is one of the most popular and cost-effective options available today. By encasing the underfloor heating pipes within the screed or concrete, the entire floor warms up like a large storage radiator, efficiently distributing heat throughout the space. This type of system is typically used in new build homes, extensions, or conservatories.

Staple System

A foil-faced insulation board, such as Kingspan or Celotex, is first laid onto the concrete subfloor.
The pipework is then clipped directly onto the insulation board for secure placement.
After testing the pipework, it is covered with either a traditional sand and cement screed or a pumped anhydrite screed.

Clip Rail System

Our clip rail system is perfect for situations where clipping directly to the insulation isn’t possible, often due to floor height restrictions limiting insulation thickness.
The self-adhesive rails come in 1-metre lengths and can be easily adhered directly to the subfloor.
Pipes are clipped into the rails at the required spacing, ready for screed installation as usual.
Note: If thicker foil-faced insulation boards cannot be fitted, you can opt for our ProWarm™ insulated tile backer boards, which are only 6mm thick. These can be adhered to the concrete sub-base with flexible tile adhesive, and the clip rail can be attached directly to them before applying the screed as normal.

ProCrate Egg Crate

This system uses a traditional method for underfloor heating installation.
Pipes are clipped into an egg crate-style plastic tray.
The tray is covered with screed as usual.
Lacks insulation beneath the tray, which can impact efficiency.
Generally more expensive than direct clipping systems.
