Air to water Multifunction Air Source 20kw air conditioner heat pump
Total solution for home and light commercial use:
1) Domestic hot water all year round
2) Space heating in winter
3) Space cooling in summer
All hydraulic parts are located within the outdoor unit.
Water pump, expansion vessel, buffer tank and safety equipment have already been fitted inside the outdoor unit.
The hydraulic connection rather than refrigerant makes installation much quicker and easier for the domestic installer.
