The photovoltaic off-grid boiler produces hot water directly from inexpensive direct current
connected photovoltaic modules. It is ideal for preheating water. For this the
Boiler mounted in front of an electric instantaneous water heater or, for example, a gas boiler. The already preheated water no longer needs to be reheated, or only to a small extent. Through this
Less electrical energy or gas is required and energy costs fall.
Depending on the application, the energy costs for hot water preparation can be reduced by around 60% - 80%
be lowered.
