Brenton Gypsum Fibre Overlay Underfloor Heating Kit – 2 Zones, 150mm Centres

Plan a 2-zone wet underfloor heating installation with the Brenton gypsum fibre overlay kit, specified for 12mm pipe at 150mm centres. This package brings together the floor-system components, manifold, pump/blending pack and heating controls listed below. Two heating zones allow two areas to be planned around separate temperature schedules. Decide which rooms share each zone before selecting the area package, and have the installer confirm the control wiring and loop allocation. Select the area option that matches your project, then confirm the component quantities and floor construction before ordering.

Specifications

Choosing and using this product

The heavy overlay system combines routed gypsum fibre boards with 12mm pipe. It differs from the 16mm-pipe EPS and XPS systems, so order the correct pipe connectors and returns for the design. Board thickness is only one part of the finished floor height. Two heating zones allow two areas to be planned around separate temperature schedules. Decide which rooms share each zone before selecting the area package, and have the installer confirm the control wiring and loop allocation.

Planning the controls and any extras

• View Heatmiser Slimline thermostat specifications
• Review Heatmiser UH8 wiring-centre specifications

Check component compatibility against your system specification before ordering.

Frequently asked questions

What does the 2-zone designation mean?

Two heating zones allow two areas to be planned around separate temperature schedules. Decide which rooms share each zone before selecting the area package, and have the installer confirm the control wiring and loop allocation.

Does this kit use the same pipe as EPS or XPS overlay kits?

This gypsum fibre kit specifies 12mm pipe. The EPS and XPS packages on this site specify 16mm pipe. Match board channels, manifold connectors and any extra pipe to the selected system.

Does the kit area guarantee it will heat my property?

No. The area option identifies the package choice. Suitability and heat output require a room-by-room heat-loss calculation, the intended flow temperature and the proposed floor construction.

What should I confirm before ordering?

Ask for the exact bill of materials for the chosen area: pipe length, manifold ports, thermostat quantities, actuators and wiring centre requirements. Confirm any insulation, adhesives and floor-finish layers separately.
