Main highlights

Safe and reliable: R290 content of refrigerant: 1.95 kg. In view of the flammability of refrigerants, the silver soldering technology is used to ensure a firm welding and avoid leakage. The safety valve can quickly drain the refrigerant in the event of a leak to prevent the refrigerant from entering the water system and the interior. An independent control box disconnects the electrical components to prevent the refrigerant from leaking and colliding with the electrical components, which could pose a hazard.
Intelligent frost protection and defrosting: the Smad air heat pump has multiple frost protection to prevent the system from freezing and automatic intelligent defrosting. With the EVI technology, the heat output is still excellent even at low temperatures of -15°C, and it can still work even at outdoor temperatures of -30°C. Electricity can also be used to support work when the air heating is not ideal for heating or cooling.
Energy efficient A+++: The Smad inverter air heat pump uses the refrigerant R290, which is harmless to the ozone layer and meets the environmental regulations of several countries. The full inverter technology increases energy saving by 15%. COP up to 4.92
Easy installation and user-friendly: Smad inverter air heat pump configuration includes electric heating element, expansion tank, outlet valve, water pump, etc. No third-party accessories are required (no tank). WiFi can be installed. This device has a night mode to create a quiet and comfortable living environment. Holiday mode reduces energy consumption and saves electricity costs when the user is away from home for a long time.
Cooling, hot water, heating: the Smad inverter air heat pump is equipped with a high-quality compressor and combines the functions of an air conditioner and a water heater for heating, cooling and heating tap water. 5 operating modes: hot water, cooling, heating, heating + hot water, cooling + hot water. Maximum water temperature up to 60°C (30°C - 60°C) for different end water temperatures (underfloor heating/heating/air tray)
