- High-quality enamel-lined water tank provides excellent corrosion resistance and ensures a longer service life.
- Low-noise compressor technology delivers efficient heating with quiet operation.
Your Trusted Heat Pump Hot Water Heater Manufacturer in China
Haoha heat pump hot water heaters are self-contained systems with compressors, evaporators and a storage tank enclosed in one unit. With this design, you can easily transport and deploy these heat pumps on your site.
Heat pump hot water heaters absorb heat energy from the surrounding air and transfer it to the refrigerant inside the microchannel heat exchanger. The refrigerant evaporates and is compressed by the compressor, increasing its temperature. This high-temperature refrigerant then releases heat through the heat exchanger to efficiently heat the water inside the storage tank.
By using advanced compressor technology and high-efficiency microchannel heat exchangers, our heat pump hot water heaters deliver excellent heating performance while significantly reducing electricity consumption, so you don’t have to worry about expensive water and compressor costs. More importantly, Haoha’s all-in-one heat pump hot water heaters help reduce initial installation costs by integrating the heat pump system and water storage tank into a compact unit.
To achieve outstanding heat transfer efficiency, Haoha heat pump hot water heaters are equipped with aluminium microchannel heat exchangers. The flat tubes, headers, and fins are assembled and brazed together at high temperatures, creating a compact structure with excellent thermal conductivity and improved system efficiency.
In addition, our heat pump hot water heaters feature enamel inner tanks. The enamel inner tank provides excellent corrosion resistance, extending the service life of the water heater while reducing the total cost of ownership. At the same time, it ensures stable heat transfer performance and long-term reliability.

Higher heating efficiency, lower refrigerant charge, higher COP, and lower unit cost, providing significant cost advantages.
Higher safety level, easier maintenance, and no additional explosion-proof requirements. However, it is not recommended for extremely cold regions, as low temperatures may affect heat exchange performance.
Flexible installation compatibility and more uniform heat dissipation. Sufficient ventilation space needs to be reserved on the side of the unit.
Space-saving design with upward air discharge, offering better rain and dust protection and improved durability.
The wall-mounted design saves floor space and is specially designed for small apartments. The maximum capacity can reach approximately 110L.
Higher capacity range, specially designed for high hot water demand projects and commercial applications. Easy inspection and maintenance help reduce after-sales costs.
Strict Quality Control for All Your Heat Pump Hot Water Heaters
Every heat pump hot water heater produced by Haoha undergoes strict quality inspections throughout the manufacturing process.
The inner tank is produced according to a rigorous manufacturing procedure. After completion, each tank must pass two pressure tests and one pulse test to ensure its strength, durability, and reliability. Only tanks that successfully pass all tests are approved for use in heat pump water heater production.
In addition, Haoha’s microchannel heat exchangers are fully manufactured in our own factory, ensuring stable quality and production control. The heat exchanger adopts aluminum fins, and each fin is evenly coated with thermal conductive silicone grease before film covering. This process significantly improves insulation performance and heat transfer efficiency, ensuring better system performance and longer service life.
Can be used in combination with large-capacity split or all in one heat pump hot water heaters to meet hot water demand at multiple points throughout the home, and can be combined with solar to form a hybrid heating system.
Heat pump hot water heaters can provide a continuous and stable hot water supply for hotels. Compared with traditional electric water heaters and gas water heaters, they offer lower energy consumption and significantly reduce daily operating costs.
Equipped with commercial heat pump water heaters , which provide a steady supply of hot water for the processing operations, ensuring a reliable water supply.
All-in-One vs Split
The compressor and water storage tank are integrated into a single unit. The refrigerant piping is pre-connected before delivery, so installation only requires connecting the water inlet and outlet pipes and power supply. The system is simple and fast to install.
With shorter refrigerant piping, lower flow resistance, and reduced energy loss, the all-in-one heat pump hot water heater provides stable and efficient heating performance.
The system consists of two separate parts: the outdoor compressor unit and the water storage tank. During installation, the refrigerant pipes must be connected and welded on site, which makes the process more complex.
The outdoor unit is installed separately, allowing better air circulation and more stable heat exchange performance, especially suitable for large-capacity systems and high hot water demand applications.
