R410A Residential Hot Water Heat Pump
The R410A Residential Hot Water Heat Pump is a practical air source heating solution for supplying domestic hot water in residential buildings. It transfers heat from outdoor air to water, providing a stable hot water supply with lower energy use than conventional direct electric heating.
With four capacity options from 3.5 kW to 9.6 kW, the series can meet different household hot water requirements while maintaining a compact and integrated system design.
Reliable Domestic Hot Water Supply
The system delivers a 55°C rated water temperature and can reach up to 60°C, making it suitable for daily bathing, kitchen, and household hot water needs.
Depending on the selected model, hot water production ranges from 75 to 206 L/h, allowing the system to be matched to different residential demand levels.
Efficient Air Source Technology
The heat pump uses ambient air as its energy source and transfers the recovered heat into the water system. With a COP of up to 3.96, it provides efficient heating performance for residential hot water production.
The unit is designed to operate at ambient temperatures from -7°C to 43°C, supporting stable operation in a wide range of outdoor conditions.
Integrated Design for Convenient Installation
A built-in Wilo water pump can be directly connected to the water tank, helping simplify the water circulation system and installation process.
The unit also incorporates a rotary compressor, tube-in-shell heat exchanger, electronic expansion valve, and four-way valve, providing a complete heat pump system within one unit.
Simple Operation & Automatic Defrost
The LCD control panel provides convenient access to essential system settings, including water temperature, operating mode, timing, E-heater, and defrost functions.
The four-way valve enables automatic defrosting, helping maintain reliable operation when frost forms on the outdoor heat exchanger during low-temperature conditions.
Flexible Heating & Cooling Operation
The heat pump supports both heating and cooling functions, providing flexibility for different system configurations.
With IPX4 protection, the unit is designed for dependable operation in residential environments.
Applications
The R410A Residential Hot Water Heat Pump is suitable for houses, villas, apartments, and residential domestic hot water systems. It can be used for new installations, system upgrades, and replacement of conventional residential water heating equipment.
