Daikin VRV Heat Recovery Hydrobox R410A
The Daikin VRV Heat Recovery Hydrobox (R410A) offers an exceptionally energy-efficient solution for generating domestic and commercial hot water by harnessing heat recovery technology. Designed for seamless integration with Daikin VRV V Heat Recovery systems, this air-to-water system captures waste heat from areas requiring cooling (such as server rooms or office zones) and transfers it to produce hot water.
By operating via heat pump technology, the Hydrobox delivers up to 17% running cost savings compared to conventional gas boilers while completely eliminating the need for gas connections, oil storage tanks, or flue systems.
Available models – High Temperature: Daikin HXHD125A8, HXHD200A8, low temperature – HXY080A8, HXY125A8.
Key Features & Benefits
-
High-Efficiency Heat Recovery: Extracts “free” heat from cooling zones to supply hot water for sanitary use, underfloor heating, radiators, and air handling unit (AHU) applications.
-
High Water Temperatures Without Auxiliary Heating: Reaches leaving water temperatures from 25°C up to 80°C purely via heat pump technology without relying on electric back-up heaters.
-
Wide Ambient Operating Range: Delivers consistent hot water in outdoor temperatures ranging from -20°C up to +43°C.
-
Compact & Flexible Installation: The indoor unit and domestic hot water tank can be stacked vertically to save footprint or placed side-by-side where ceiling height is limited.
-
Solar Thermal Integration: Designed for direct connection to thermal solar collectors to maximise renewable energy savings.
-
Integrated Hydraulic Components: Includes built-in water-side components with weather-dependent set point or thermostat controls, simplifying design and installation.
