Thermomat Pump Stations

Thermostatic pump groups consist of:

  • a boiler circuit circulation pump
  • a thermostatic mixing valve
  • a floating check valve
  • any additional components

They automatically mix the return water from the heating system (or storage tank) with the outlet water from the boiler, thereby maintaining the return water temperature to the boiler at a specified minimum temperature.

The floating check valve allows the boiler to be cooled by gravity circulation during a power outage and simultaneously prevents the storage tank from cooling down via the boiler after it has gone out.
