The X6-B Heat Pump Water Heater is an innovative air source heat pump water heater that revolutionizes hot water supply with energy efficiency, environmental friendliness, and intelligent control. By harnessing natural heat from the air, this system eliminates the need for fossil fuels or excessive electricity, delivering a sustainable way to produce hot water for households, villas, and small commercial spaces. The X6-B combines advanced technology—such as a Panasonic compressor and intelligent heating modes—with a space-saving design, ensuring reliable, constant-temperature hot water anytime, anywhere. Whether you need hot water for showers, kitchens, or SPA facilities, this eco-friendly water heater offers exceptional performance while reducing carbon emissions and utility bills.

The X6-B Heat Pump Water Heater is powered by a Panasonic compressor specifically designed for air source heat pumps. This high-quality compressor ensures efficient heat absorption and compression, delivering consistent heating capacity and long-term reliability. It operates smoothly even in varying temperature conditions, making the water heater suitable for diverse climates.
Featuring an all-in-one heat pump design, the X6-B integrates the compressor, water tank, and heat exchanger into a single unit, eliminating the need for separate boiler rooms or storage spaces. Its vertical structure and compact footprint save valuable floor space, allowing installation on roofs, balconies, kitchens, or garages. The simple, sleek appearance blends seamlessly with residential and commercial environments.
The X6-B offers three heating modes—AUTO, ECO (economic), and HEATER (fast heating)—to meet different hot water needs. The ECO mode prioritizes energy savings by maximizing air source heat utilization, while the HEATER mode provides rapid heating for urgent use. The AUTO mode automatically adjusts based on water temperature and usage patterns, ensuring optimal efficiency and convenience. Timer setting functionality allows users to schedule heating times, further enhancing energy conservation.
Equipped with a 360-degree supercharged foaming polyurethane insulation layer, the X6-B’s water tank retains heat effectively, preventing temperature loss and reducing energy consumption. The thick insulation layer ensures that hot water remains at a constant temperature for extended periods, eliminating the need for frequent reheating and ensuring a steady supply of hot water.
The X6-B Heat Pump Water Heater supports remote mobile phone control, allowing users to adjust settings, monitor water temperature, and start/stop heating from anywhere. This intelligent feature enhances convenience—whether you’re at work, traveling, or at home—ensuring hot water is ready when you need it. The user-friendly app interface makes operation intuitive for all users.
As an air source heat pump water heater, the X6-B harnesses natural heat from the air, producing no exhaust gases, carbon emissions, or harmful pollutants. It reduces reliance on fossil fuels and electricity, contributing to environmental protection and carbon neutrality. Using this water heater helps lower your carbon footprint while complying with green energy standards.
The X6-B features full intelligent reverse defrosting, which automatically removes frost from the evaporator in cold weather, ensuring consistent heating performance. Additionally, the fault self-check function detects and alerts users to potential issues, such as temperature abnormalities or compressor malfunctions, enabling timely maintenance and preventing costly repairs.
The water heater is equipped with 316 stainless steel or copper heat exchange coils, which offer excellent corrosion resistance and heat transfer efficiency. These durable coils ensure long-term performance, even in hard water conditions, and reduce the risk of leaks or damage.
