Vario PRO Underfloor Heating is the original patented system that combines electric underfloor heating cables with an uncoupling, crack isolation and waterproofing membrane. Vario PRO Underfloor Heating brings you all the benefits of an electric underfloor heating system and movement matting, all in one easy to install solution.
Vario PRO Underfloor Heating Mat protects floor coverings from uncoupling or delamination when laid over cracked or unstable substrates, and is usually laid over the entire floor surface. Vario PRO Underfloor Heating Cable can be then installed in any areas that require heating – the beauty of this is that you can put it in just the areas that need it, creating a very efficient and cost-effective heating solution. The entire assembly is low profile – only 5.5mm floor height build up.
Vario PRO Underfloor Heating Cable:
Vario PRO Underfloor Heating Cable uses the unique TwistedTwin electric cable technology that combines two heating conductors in a unique twisted configuration. This creates a robust and flexible cable that is specifically suited to laying over unstable or cracked substrates.
The cable has an output of 12W/Lm and will provide 130W/m2 when spaced at 3 rows. Spacing the cable at 2 rows apart increases the heat output to 195W/m2.
This cable cannot be cut. However multiple cables can be used in one installation, connected to the same thermostat, but the total system load/draw must be under 3600W/16A – which equates to a floor heating area of approx. 23m². Larger areas than 23m² with one thermostat are possible, using a Thermonet Snubber Unit – call us for more details on this.
Vario PRO Underfloor Heating is easy to install. We recommend laying Tile Backer Board onto the floor area first to provide a thermal insulation layer underneath the membrane. This drastically reduces downward heat loss and speeds up the initial warm up time of the cable, but is not mandatory. Fix the uncoupling membrane to the entire floor area using a suitable adhesive (we recommend using Ardex AF200 or Mapei Ultrabond VS90 Plus for wooden substrates such as floorboards, any flexible cement-based tile adhesive is suitable for concrete, screed, tile backer board substrates) and then lay the Vario Pro heating cable into the grooves in the matting until you’ve covered the desired area/s that you want to heat. Tiles can then be laid directly over the installation using a flexible tile adhesive. Levelling compound can also be poured over the membrane to fully encapsulate the installation prior to tiling.
Thermostats and controls:
Vario PRO Underfloor Heating can be controlled by any ThermoSphere Thermostat. We stock a range of different thermostats with many useful features such as 7-day programming and WiFi control.
