For New-Build or Renovation Projects

The Econna Joisted Floor System is a water underfloor heating system designed specifically for use with battened or joisted floors. It is installed over traditional timber joists in either new-build or renovation projects and utilises the space between joists for insulation material whilst also allowing room for other plumbing and electrical services.

Diffusion Plates

The underfloor heating system utilises aluminium diffusion plates for even heat distribution and is suitable for almost any floor finish, in particular where the flooring (wood, carpet or vinyl) may be replaced from time to time. If using tiles as a final floor finish, additional layers of plywood or tile backer board may be required to create a rigid base.

For Use with Timber Joists

Econna Joisted Floor System is a composite wood load-bearing slotted 22mm floor with return ends. It is designed to fit on top of standard wood joists of 400mm to 600mm c/c max; this replaces the standard board in the floor construction.

The system can use Warmup’s 16mm Pex-a or PE-RT heating pipes, which are built into the structural floor allowing rapid heat-up times. If the boards need extra support, a carpenter may be required.
