SG Ready function

SUNSYSTEM MONO PLUS is a new generation of air-to-water inverter monoblock heat pumps, developed with the environmentally friendly refrigerant R32 (with low global warming potential). The series is designed to fully cover the heating , cooling and domestic hot water (DHW) needs of single-family houses and residential buildings, using renewable energy from the outside air.

The heart of the heat pump is a highly efficient inverter compressor with EVI technology (Enhanced Vapour Injection – direct injection of steam into the compressor), which guarantees stable and efficient operation even at extremely low outdoor temperatures – down to -25°C . This makes MONO PLUS a suitable solution for all climate zones in Bulgaria and Europe.

What objects is it suitable for?

The MONO PLUS single-phase models are designed for objects with domestic single-phase power supply - single-family houses, apartments with autonomous heating, small offices, villas, etc. The choice of a specific model depends on the heated area, the level of thermal insulation and the type of heating installation (underfloor, radiators or combined).
