Calla Verde M is a modern, inverter-operated air source heat pump that has been designed as the primary heat source for residential buildings with space cooling in summer. Calla Verde M heat pumps are the first certified units on the domestic market with refrigerant R452B, which has been produced for high-efficiency heat pumps and meets strict environmental requirements.

The use of an inverter compressor, with the latest R452B refrigerant and modern components, made it possible to achieve high COPs of up to 7.32 and SCOPs of up to 4.65 and high heating water temperatures of up to 65°C (without using an electric heater).

Calla Verde M heat pump is a device prepared as an independent, complete source of heat for newly built, but also modernized buildings with floor and radiator heating. The use of an inverter compressor with modulating capacity eliminates the need to mount a buffer tank, which materially curbs the cost of heat source fitting and saves space. Calla Verde M pump together with hydraulic modules is a ready-made heating solution for the building. The performance of the pump is confirmed by tests carried out by a certified research institute.
