Underfloor heating system

Underfloor heating system

Underfloor heating is a low temperature, accumulative heating system. Properly planned, made and used guarantees constant temperature and room humidity, creates the most recommended indoor climate with temperature warmer at foot level than at the head.

Cassette temperature limiter RTL. Used for heating medium temperature limiting in an underfloor heating system pipe. The system should not exceed the area of 20 m2, total heating pipe loop length of 100 m and inner pipe diameter of 12 mm. The loop of the underfloor heating system can be connected to the central heating system that meets 70/55˚C specifications and by means of an over-temperature protection the heating medium must not exceed the temperature of 50˚C. Thanks to using a temperature limiter there is no need for installing a mixing valve and an extra circulation pump. Used in combined systems of underfloor and radiator heating.50°C.

Cassette set with a thermostatic valve for underfloor heating. Used for heating medium temperature limiting in an underfloor heating system pipe. The system should not exceed the area of 20 m2, total heating pipe loop length of 100 m and inner pipe diameter of 12 mm. Thermostatic valve responds to changes of room air temperature. The underfloor heating system should be provided with over-temperature protection preventing the heating medium from exceeding 50 ˚C. The set includes a flush cassette, in which thermostatic valve with a built-in air vent and a Brillant series thermostatic  head. The cassette is covered with a front lid.

Actuator. Provides precise and reliable temperature control in underfloor, wall or ceiling heating systems, radiators, convectors, valve controls. Designed for installation on normally closed control valves. Performs various control and regulation tasks as a two-step actuator (open/close). The wax element is heated electrically by the applied operating voltage and silently opens the valve. Without any operating voltage the wax element is no longer heated and the actuator closes.

Cassette RTL combi valve for underfloor heating. Enables control of temperature in the room and in underfloor heating installation at the same time. Consists of flush-mounted cassette with thermostatic valve and temperature limiter valve (RTL) inside. On the thermostatic valve thermostatic head from Brillant or Diamant series is mounted. On the RTL valve RTL head is seated. Thermostatic valve reacts on changes in room temperature and RTL valve ensures control of heating medium temperature in underfloor heating pipe system.
