Blog / retrofit underfloor heating

Variotherm modular wall heating system is a modern, high output, efficient and cost effective heating solution that can be installed where other heating methods can’t be used.

Retrofitting with underfloor heating is all about upgrading for comfort and efficiency, and to do this most effectively, we recommend that every customer invest in underfloor heating insulation for their system. This allows your system to work to its full potential, providing a high level of heat output at a more cost-effective rate. In this guide, we’ll be going through all the reasons why underfloor heating insulation is so important. We’ll give you all the information and advice you need to be able to make an informed decision when it comes to purchasing insulation for your retrofit project.

Wall heating systems work very similar to underfloor heating in that they heat a room predominantly by radiation (like the sun) as a result of pumping warm water through looped pipes. Wall heating systems are often used as an alternative to UFH in renovation projects. Until the recent additions of retrofit and wall heating systems, installing ufh resulted in the floor having to be excavated. Although Retrofit UFH kits have eliminated the need to fully excavate flooring, this does not mean wall heating systems are now redundant. It is not always economically viable to re-lay flooring after installing ufh such as in renovations of older homes.

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

One of the most frequent questions we get asked from customers wishing to retro-fit underfloor heating (UFH) is what is best/most cost effective, excavate the existing floor or add a board system? Whilst costs can vary hugely by area, tradesman etc., we've compiled a list of comparative costs for each type of UFH install and labour etc. on a typical approx. 75m2 project:
