Microwell followed environmental responsibility demands and reduced CO2 footprint by more than 67% in every new heat pump piece produced.

In 2020 Microwell introduced an alternative: the HP BLACK line of inverter heat pumps perfectly finetuned for seasonal use. This move was to provide an alternative for reliable on-off units and also to complete the range of inverter heat pumps designed for 4-season operations with ambient temperature range from -15°C. Apart from lower noise, the new inverter BLACK line operates, it also offers more options to reduce the energy bill through higher efficiency than traditional on/off models.
