Fothermo Photovoltaic Boiler 10 Liters

The photovoltaic boiler offers the ideal solution for a cost-effective and independent hot water supply. Once installed, the boiler produces free hot water for years.
The 10 liter boiler is ideal for vacation homes and garden or mountain cabins. With its small size, the 10 liter boiler can be used almost anywhere

Installation
Installation of the photovoltaic modules is very simple thanks to plug & play connections. The modules are plugged directly into the boiler via standard plug contacts (MC4). Optionally, an extension cable can be used to bridge longer distances between the photovoltaic modules and the boiler. (Photovoltaic modules and extension cables are not included in the delivery, they can be purchased separately in the online store)

Reheating
In case there is not enough energy from the sun to heat up the water for a longer period of time, the boiler can be reheated automatically via the optional 230V reheater. To activate the reheating, a minimum temperature can be set on the boiler. This could be 35 °C, for example. As soon as the temperature of the water falls below the set minimum temperature, the water is reheated via electricity from the mains. During the reheating phase, existing photovoltaic energy is also converted into heat. The reheating process is automatically terminated as soon as the water has reached the set minimum temperature again. (The reheater is not included in the scope of delivery)
The maximum water temperature of the boiler is 65 °C. When the boiler is completely heated, about 24 liters of 34 degree water can be taken from it.
