Heat Pump Mr.Green, Output 21 kW, for Pools 40–75 m³

The Mr.Green 21 kW is the most powerful model in the Mr.Green range and is intended for larger pools with a volume of 40 to 75 m³, where rapid heating and reliable temperature maintenance are required even at lower outdoor temperatures. The ecological R290 refrigerant with a GWP of 3 ranks this product among the most environmentally friendly heat pumps on the market.

Inverter control with an electronic expansion valve (EEV) ensures smooth output modulation and COP optimisation at every operating point. Compared to conventional heat pumps without EEV, the Mr.Green achieves 20% higher efficiency, which is significantly reflected in operating costs, especially during a longer bathing season.

At 21 kW output, the Mr.Green 21 kW is a more affordable alternative to the premium Mr.Silence 30+ range, while offering comparable heat output and a modern ecological design. The device is ready for installation in new and existing pools, and its connection to the hydraulic circuit is standard.
