Variocomp - Retrofit Underfloor Heating for Existing Floors

by UFH1

We answer your questions about laying underfloor heating onto existing floors.

“How can I add underfloor heating to existing floors?”

The main problem with conventional wet Underfloor Heating and existing properties, is the upheaval of existing floors. The systems’ profile is usually too high to be laid over existing floors, as insulation/screed is fitted and increases the height by 75mm-150mm. Due to this issue, UFH1 now provide an innovative and cost effective solution.

“How can I add underfloor heating to concrete floors?”

Many consumers ask us this question. The solution to adding underfloor heating to permanent concrete flooring is a ‘retrofit’ system – a system that comprises of modular boards with grooves to fit warm water pipes, this can be used over any floor type and can be used in any room!

UFH1 are proud to be a UK distributor of the VarioComp system from Variotherm Austria. VarioComp is a unique new range of retrofit Underfloor Heating boards. The product is made from Fermacell Gypsum Fibre, which gives excellent thermal mass – something not achieved with EPS or XPS systems. The systems’ main selling points are its ultra-low profile (only 18mm) which minimises the height of the finished floor level, it’s rapid heat output (due to the Gypsum Fibre material) and it also has the highest heat output of any retrofit underfloor heating system available in the UK – due to a pipe spacing of 100mm!

“Is Variocomp retrofit underfloor heating a long term solution?”

This water based system is compatible with a number of heating appliances – gas/lpg boilers/biomass/heat pumps etc., which means it is a great long term solution should you choose to change the heating appliance, for example from a boiler to a heat pump.
