R410A Air Source Water Heater Heat Pump for Residential Use
The R410A Air Source Water Heater Heat Pump is designed for residential domestic hot water applications, using ambient air as a renewable heat source to efficiently heat water. With multiple capacity options and a built-in water pump, it can be integrated directly with a hot water tank for a practical and reliable heating solution.
Efficient Hot Water Heating
Using air-to-water heat pump technology, the unit transfers heat from the surrounding air to the water system. The available models provide heating capacities from 3.5 kW to 9.6 kW, with COP values up to 3.96.
The system delivers a rated water outlet temperature of 55°C and can reach up to 60°C, making it suitable for everyday residential hot water requirements.
Direct Tank Connection
A built-in Wilo water pump simplifies system installation by allowing direct connection to the water tank. This integrated design helps reduce additional components while providing stable water circulation during operation.
The high-efficiency tube-in-shell heat exchanger is designed for effective heat transfer between the refrigerant and water, supporting consistent hot water production.
Stable Performance in Cold Weather
The R410A heat pump operates in ambient temperatures from -7°C to 43°C. An automatic defrosting function helps remove frost from the heat exchanger during low-temperature operation, maintaining reliable system performance.
The unit also incorporates a reliable rotary compressor, high-precision electronic expansion valve and four-way valve for stable operation.
Simple Residential Control
A clear LCD control panel provides straightforward operation and monitoring. The system supports both heating and cooling functions, giving installers greater flexibility when configuring different residential HVAC and hot water systems.
