tubra®-eTherm C

Power to heat

External electric heater for loading buffer storage tanks with target temperature for optimal storage stratification.

  • heating power 9 kW ( 3 * 3 kW )
  • intrinsically safe incl. thermostat, safety temperature limiter, pump control, power contactor
  • optional reheating function
  • applicable for external energy management systems for thermal storage of PV surplus power
  • optimal layer loading for immediately usable heat
  • complete use of the available storage capacity in contrast to heating rods
  • hydraulic, thermal supplement for energy management systems from
    my-PV, Fronius, solaredge, SMA, Varista
