The integration of a fothermo solar storage tank reduces the gas heating load, lowers operating costs and improves energy efficiency.

The solar boiler is ideal for reducing the electricity costs of an electric instantaneous water heater. Preheated water from the solar boiler flows into the instantaneous water heater when needed. In the best case scenario, the heater doesn't even need to heat up. This saves €300 - €400 per year. The whole system usually pays for itself after 3 - 4 years.

The fothermo hybrid boiler provides free and CO2-neutral hot water. Since the installation is very simple, the entire system can be put together by the user. This makes the fothermo hybrid boiler ideal for use in a tiny house.
