NovaPro Overlay Dual Purpose Wet Underfloor Heating Kit – 40m²

The NovaPro 30m² Dual Purpose Overlay Wet Underfloor Heating Kit is designed for bathrooms, bedrooms or smaller adjoining spaces. Its 20mm low-profile panels provide a route to installing a water-based underfloor heating system over a suitably prepared existing floor, without the depth of a conventional screeded installation. This kit is a practical choice for a modest renovation where floor height matters.

Why choose this 40m² overlay underfloor heating kit?

  • 20mm low-profile overlay panels help keep floor build-up to a minimum.
  • 150mm pipe centres support even distribution of warmth across the planned heated area.
  • Dual-purpose flooring compatibility: suitable for tile and wood finishes when installed to the relevant floor-finish and panel instructions.
  • Water underfloor heating components: includes pipework, mixing controls, a circulation pump and a 2-zone manifold.
  • Designed for approximately 40m² of heated floor area, subject to layout and heat-loss calculations.

Planning your installation

Check the net heated area, subfloor preparation, insulation, heating design and maximum pipe circuit lengths before ordering. The 20mm measurement refers to the overlay panel only; adhesives, levelling layers and your final floor covering can increase the finished floor height. Thermostats, wiring centres and other installation accessories may need to be selected separately. If you would like help choosing components for your project, contact Underfloor Heating Trade Supplies before ordering.

Frequently Asked Questions

What makes the 40m² NovaPro Overlay dual purpose?
The 40m² NovaPro Overlay is dual purpose as the 20mm overlay panels accept 16mm pipe and are suitable beneath tile, wood, laminate and vinyl. That flexibility makes the 40m² kit a practical option for mixed-finish homes or small commercial rooms needing a low-height solution.
What is an overlay board?
An overlay board is a thin, grooved panel used in underfloor heating systems, designed to sit on top of an existing floor without needing screed. It holds the heating pipes or cables in place, allowing heat to spread evenly. Overlay boards are ideal for retrofit projects because they’re low-profile, quick to install, and compatible with most floor finishes. Additionally, overlay boards can work with both electric and water-based underfloor heating systems.
How low is the floor build-up with a 40m² NovaPro Overlay Kit?
The 40m² NovaPro Overlay Kit depth is only 20mm for the overlay panel, allowing pipework to be routed without major floor excavation. That shallow build-up helps keep thresholds manageable and speeds installation in retrofit scenarios compared with traditional screeded wet systems.
