If you are planning to renovate individual rooms to enjoy the comfort of a floor heating system in spaces that were previously heated with conventional radiators, we recommend the use of our return temperature limiter Schlüter-BEKOTEC-THERM-RTB. It limits the high water temperatures of your existing heating system to make them suitable for use with our energy-efficient floor heating system BEKOTEC-THERM. The unit is installed within the wall. Schlüter-BEKOTEC-THERM-RTB runs automatically without any additional auxiliary energy.
