Integrated electricity meter 3x 65 A Integrated 3-phase electricity meter with identical functionality.

Desuperheater for high efficiency hot water heating Integrated device that uses a separate hydraulic circuit to remove the heat of superheated steam at the compressor outlet and increase the efficiency of hot water preparation (heating). When the compressor is in operation (heating and cooling mode), part of its thermal energy is permanently transferred to the hot water tank.

How it works

Ground-to-water heat pumps extract energy from the ground by means of a vertical or horizontal collector. Antifreeze circulates through the collector and removes ground heat. Thanks to the constant temperature of the ground, the heat pump has a stable source of energy throughout the year. The heat extracted from the ground is then transferred to the building. The system achieves a seasonal efficiency up to 5.5 times higher thanthat of a conventional electric boiler.
