Hot water without gas, without bills. Just with the sun.
Hot water that comes directly from the sun
FROG is the first photovoltaic water heater patented by Sunerg Solar: an intelligent, ecological and all-Italian system, which produces domestic hot water thanks to solar energy.
Ideal for homes, second homes, farmhouses, accommodation facilities or wherever hot water is needed all year round, because it works by connecting the panels to the boiler with a single cable, so due to its simplicity it can be installed by a thermal or electrical installer with one eye on the wallet and one on the environment.
