Radiant Heating Systems for your Home
Retrofit Low Profile Underfloor Heating » Feel Warm - Reduce Energy Costs
Want to upgrade your home with an underfloor heating but without removing the entire floor? FLEXIRO's low profile wet underfloor heating for retrofitting existing buildings can in many cases be installed on the existing floor surface thanks to its low, 17 mm construction height.
At the heart of all our underfloor heating, wall and ceiling heating kits is a 10 mm polyethylene pipe that can be laid flexibly in tight loops and thus ensures particularly even heat distribution. There is a choice between clip rail, knobbed mats and drywall systems to suit almost every spatial prerequisites. The installation directly below the surface enables a quick warm-up. The thin radiant heating kits are connected to the existing heating system via return temperature limiter and are individually controlled. Additionally, low supply temperature save energy costs.
