Quickly and directly find documentation on system components for power to heat and solar thermal energy.

Power to heat

Surplus photovoltaic power not used by self-consumption can be used for regenerative heating of the buffer storage tank.

The tubra®-eTherm is a hydraulic unit with integrated control for thermal storage of photovoltaic power for self-consumption optimization. The compact hydraulic unit can be connected modularly to hot water tanks with an integrated heat register and buffer tanks with heating water.

  • applicable on drinking water or buffer storage tanks
  • optimal for retrofitting to existing storage tanks
  • energy storage in thermal accumulators with significantly higher storage capacities than in batteries
  • Control of the charging temperature for immediately usable heat
    tubra®-eTherm P+ and C+
  • no required minimum terms or minimum services
  • CE compliant in terms of EMC and electrical safety
