Combinability with solar energy
YUTAKI S80 allows the combination with solar panels for the Domestic Hot Water operation. The air to water heat pump
will provide a part of the required heating, and the rest of required heating will be provided by the solar panel.
As it is known, the solar panels get the heat from the solar radiation, resulting in an environment friendly system.
