R410A Air Source Heat Pump for Domestic Hot Water
Efficient Air-to-Water Heating for Residential Hot Water
The R410A Air Source Heat Pump provides an energy-efficient solution for producing domestic hot water in residential buildings. It captures available heat from the surrounding air and transfers it to water, reducing the need to rely on direct electric resistance heating.
With four output options from 3.5 kW to 9.6 kW, the series can be selected according to different hot water demands, making it suitable for houses, apartments, villas, and other residential applications.
Turn Ambient Heat into Usable Hot Water
The system works by extracting thermal energy from outdoor air and transferring it into the water circuit through the heat pump system.
Depending on the model, the unit provides:
- Heating capacity from 3.5 to 9.6 kW
- COP up to 3.96
- Rated water outlet temperature of 55°C
- Maximum water temperature of 60°C
- Hot water production of up to 206 L/h
This air-to-water process allows the heat pump to produce hot water without relying solely on electrical resistance heating.
Built for Year-Round Residential Operation
The heat pump operates across an ambient temperature range of -7°C to 43°C.
It supports both heating and cooling operation and incorporates an automatic defrost function. When outdoor temperatures are low and frost forms during operation, the four-way valve assists the defrosting process to help maintain system operation.
Integrated Water Circulation
A built-in Wilo water pump provides water circulation within the system and allows direct connection to a suitable hot water storage tank.
The tube-in-shell heat exchanger provides the heat transfer interface between the heat pump system and the water circuit.
This integrated configuration can help simplify system planning and installation.
Straightforward Digital Control
The integrated LCD control panel provides access to the main operating functions without requiring a complicated external control system.
Users can manage:
- Water temperature
- Heating/cooling mode
- Timer settings
- Electric heater
- Defrost operation
- Operating parameters
The straightforward interface is suitable for both daily residential use and installation commissioning.
Designed for Domestic Hot Water Systems
This R410A hot water heat pump can be incorporated into residential domestic hot water systems together with a suitable storage tank.
Typical applications include:
- Houses
- Villas
- Apartments
- Residential hot water systems
- Domestic hot water replacement projects
The combination of multiple capacity options, integrated water circulation, and automatic defrosting provides flexibility for different installation conditions.
A Practical Alternative to Conventional Water Heating
By using heat available in ambient air, the system provides a different approach to conventional direct electric water heating.
For residential projects looking to improve hot water heating efficiency while maintaining a familiar air-source heat pump configuration, this series offers a practical system solution.
