Loading groups for boiler circuit

The pump groups of the tubra®-PGF series are fitting groups for the cost-effective and time-saving connection of a solid fuel boiler.

In the heating phase of the solid fuel boiler, the flow water is directly returned to the boiler.

If the temperature of the return water rises above the set value, the mixing valve opens the path to the buffer tank and the warm supply water is now made available to the tank.

  • With thermostatic return temperature maintenance for residential solid fuel appliances and solid fuel boilers
  • With electronic return temperature maintenance for solid fuel boilers
  • Power classes range from DN 25 – DN 32, 30 kW – 90 kW

The benefit for the boiler circuit system:

Our pump groups for boiler circuits ensure the necessary operating temperatures for solid fuel boilers. Several variants are available for this purpose.

  • compact modular design
  • quickly reach operating temperature
  • increase the boiler life
  • on request with regulation
  • thermal insulation compliant with GEG
