SUNSYSTEM SPLIT PLUS is a new generation split air-to-water heat pump system for heating, cooling and domestic hot water (DHW), developed with the environmentally friendly refrigerant R32 (with low global warming potential - GWP). The series combines the advantages of the split configuration - quiet operation of the indoor unit and flexibility in installation - with premium inverter technology.

The system consists of an outdoor unit (with compressor, evaporator and fan) and a compact indoor unit with built-in : control module, energy-saving circulation pump, 8 liter expansion tank, 3 kW electric heater and three-way valve for DHW. This solution significantly simplifies installation and reduces the number of hydraulic connections on site.

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 operation even at extremely low outdoor temperatures – down to -25°C .
