The power of the eTherm P is too low for my application. What options do I have to extend it ?

The eTherm P can control up to two additional consumers by means of external auxiliary relays. With the external consumers, stepless power modulation up to 12 kW can be achieved. The cascade of eTherm P and eTherm C offers a particularly effective combination. Here, the entire output is converted into heat in two hydraulic stations and the storage tank can thus be loaded in layers with a constant target temperature.
