Fastwarm™ Solid18 Multi Zone Water Underfloor Heating Kits are designed for a low-profile retro fit installations in multiple zones in whole home renovations. Allowing for individual room control using multiple thermostats for each system to set different temperatures and times accordingly.
The Fastwarm™ Solid18 panels are a gypsum-based panel which is floated across a flat surface, allowing the product to be tiled or levelled to directly without having to adhere panels to the subfloor. The plastic end return panel has multiple snap points to allow loops and leader to be positioned at either end of the room for pipe working to and from the manifold, making FastWarm™ Solid18 panel a popular choice for installers and home-owners due to their versatility and multi-purpose application.
The Solid18 panel is approved by ULTRA Tile for use with S2 tile adhesive and MSP Primer, meaning tiles can be applied DIRECTLY to the panel or can be covered with a 10mm bed of Ultra Tile 2-part levelling compound for floor finish such as Wood, LVT/Linos and Carpets.
Each system is designed based on 20m2 per zone and one controller per zone.
For example – 80m2 = 4 zones = 4 thermostats. For bespoke systems please contact firstname.lastname@example.org
