The use of solar energy for thermal applications can be realized by two very different technologies.

Solar thermal energy

With the help of solar collectors, solar heat can be transported through a water/glycol circuit to the potable hot water or buffer tank.

The pump groups for solar thermal tubra®-PGS and the solar transfer stations tubra®-ÜSTA are available in versions with and without electronic control for collector areas from 5 m² to 260 m² by cascading.

  • compact modular design
  • with speed-controlled high-efficiency pump
  • controls with pre-programmed systems for storage tank stratified charging with one or two switching valves
