Gentech Flow Switch deployed in Nu-Heat heater system

Nu-Heat, the UK’s largest specialist supplier of warm water and under-floor heating systems, have found an excellent application for Gentech’s FS-13 Flow Switch in their EnergyMaster™ thermal efficient heater system.

The switch is an integral part of the thermal store cylinder which provides heating for the underfloor system and safe domestic hot water at mains pressure at an average temperature of 50°C, via a thermal exchange unit. More efficient than conventional boilers, the system saves up to 15% on heating bills.

The EnergyMaster™ thermal store cylinder operates differently to conventional cylinders as it does not store domestic hot water. Mains water is heated instantaneously when it flows through the cylinder’s heat exchanger under mains pressure. This activates our flow switch, which runs the cylinder’s shunt pump, therefore allowing boiler water to be drawn through the primary side of the heat exchanger and for heat to be transferred to the mains water.
