Haier Multi 3S
One system for cooling, heating and hot water

Haier Multi 3S combines air conditioning (cooling and heating) with domestic hot water production – all in one system. Using R32 refrigerant, seasonal efficiency A+++ (cooling) and A++ (heating), and smart control via the hOn app, Multi 3S saves energy and space while ensuring reliable year-round operation.
Energy savings with heat recovery
During cooling, “waste heat” is recovered to warm the tank – delivering free hot water and lower running costs. Available storage tanks: 94 L (wall-mounted) and 190 L (floor installation).
Flexible indoor units for any layout
Compatible with wall, floor, duct and cassette units. The outdoor unit with a DC inverter Twin Rotary compressor provides stable, efficient operation throughout the year.
Smart control via the hOn app
Built-in Wi-Fi and the hOn app enable remote control, scheduling and consumption monitoring. ECO mode lowers the set water temperature for extra savings, while the control panel keeps adjustments simple.
