Fresh water principle: The pressureless water tank is an ideal hygienic solution since the domestic hot water circuit is separated from water storage. As a result of the continuous hot water flow in the INOX heat exchanger, there is no corrosion or scale build up.


Electrical backup (2.0 kW) ensures hot water under all circumstances. By just using the heat pump, the temperature of the water can reach up to 55°C and its production is guaranteed down to -15°C.

Easy Installation

Pressure-less water tank and limited pressure in the heat exchanger. Low maintenance: no anode means no scale and lime deposits or corrosion. Compact and designed with additional controls for easy installation and maintenance.

Energy Efficiency

Heat pump extracts renewable energy from the outside air to produce hot water. Increase energy saving and efficiency by connecting the unit to solar panels.
