PV heating

FlowSol<sup>®</sup> E electrothermal station (heating water)

FlowSol® E electrothermal station

The RESOL FlowSol® E has been especially designed for using excess power produced by PV systems. The measuring device reliably detects excess current and the integrated controller redirects it to a steplessly variable electric heater for heating a water store. Thus, excess power can be stored as regenerative heat, internal consumption can be increased while decreasing conventional heating costs.
