Ground-to-water heat pump, EVI, DC Inverter

Geothermal heat pump 26 kW

Soil-water, air-water, DC Inverter, EVI

BWHP26 is a geothermal heat pump produced by the company ALTAl in Romania / Moldova, uses DC inverter technology (compressor, fan and circulation pumps), for heating, with active cooling mode and integrated hot water preparation. With the help of this type of heat pumps bring significant savings for the comfort of the house, as the heat pump works efficiently and automatically adapts to the heat required to heat the house throughout the year. ALTAL BWHP26 achieves a high seasonal coefficient of performance thanks to EVI (steam injection) technology, which determines minimum costs to obtain quality comfort. The heat pump generates heat energy depending on the need for heating.

The heat pump has a variable speed double rotor compressor, a variable speed fan, a variable speed bronze circulation pump.
The heat pump is equipped with a removable 4-inch TFT touch screen (can be installed either on the heat pump or on the wall) and can be operated remotely via WiFi.
Thanks to the WiFi connection, it is possible to monitor all the functions of the heat pump and change the necessary settings directly from your phone, computer or tablet.
Possibility of connection to underfloor heating / cooling, radiators and fan coils.
