bathroom underfloor heating

Forte Grid System

The Warmup Forte System is the logical choice for reinforced concrete and screed floors with the pipe tied to the steel reinforcement.

Key Benefits


Fastened to reinforced bars

Pipework is fastened to the reinforced bars without impacting the integrity of the floor.


Pipe can be installed in the centre

To ensure the most heat-responsive floor, the pipe can be installed in the centre of the concrete zone.


For use in new-build projects

Designed for a secure installation in large-scale new-build projects with screed and concrete subfloors.

Compatible with Any Floor Finish

The Forte Grid System is designed for installation into load-bearing structural floors. It incorporates wire grids to which the underfloor heating pipework is attached using cable ties.

The system is either located within a concrete or structural screed and is suitable for almost any floor finish, in particular where the flooring is for a commercial application, such as epoxy paint or resin.

For Use with Structural Floors

The Forte Grid system is ideal for new-build construction projects where there is a large floor space to be heated. The reinforced wire grid bars and cable ties provide secure fastening for the heating pipes and to ensure the optimal heating output, always install the pipes in the centre of the concrete zone.

The system is a heavy-duty water underfloor heating solution for load-bearing floors and can be installed using any of Warmup’s heating pipes.
