Components of the Offgridtec 2.15kW Solar System with 200l Fothermo Boiler

Fothermo Photovoltaic Water Boiler 200 Liters - Hot Water Supplier

The Fothermo 200L water boiler utilizes solar energy for cost-effective and environmentally friendly hot water. With three independently operating photovoltaic heating elements, it delivers hot water quickly and reliably. The 3 MPP trackers and DC heating elements provide a photovoltaic heating capacity of up to 1,800W.

Flexible inlets and outlets allow for individual mounting, including the option for a circulation line. Each boiler is supplied with overpressure and non-return valves. The stand boiler can utilize a total of up to 6000Wp photovoltaic capacity. A direct connection to an existing heating system can be made through the integrated heat exchanger to ensure adequate hot water even on sunny days.

Supplementary Heating

The boiler can be supplemented in various ways if there is insufficient sunlight. One option is to use an existing pellet, gas, or oil heater, which can be connected via the integrated heat exchanger on the boiler. A temperature sensor in the boiler controls the supplementary heating. Alternatively, an electric heating element with 6/4 inch thread can be installed. The maximum water temperature is 65°C, and a heated 200-liter boiler can supply about 450 liters of water at 34°C.
