The Thermoreflux X return flow increaser is a ready-to-install, compact return flow increaser/loading valve unit for maintaining the boiler and return flow temperature for all common boiler sizes from 5 kW to 80 kW nominal output. Electronically controlled with built-in three-way mixer made of brass. An ENC10 servomotor is installed. An Environ EcoStar 25/6 high-efficiency pump is also installed. In the upper area of ​​the pump group there are flat-sealing shut-off valves (1" IG) with built-in thermometers (0-160°C).

The return flow increase (also return temperature increase or RLA) directs water from the warm flow of a heating system into the return flow. In this way, it reduces the temperature difference between the two media and thus ensures safe and efficient heating operation.
