Key Features
-
Uses next-generation natural refrigerant (R290) with an ultra-low Global Warming Potential (GWP), complies with future environmental regulations while delivering outstanding heat performance.
-
Capable of delivering flow temperatures up to 75°C, allowing easier replacement of conventional gas and oil boilers while maintaining compatibility with many existing radiator systems.
-
High seasonal efficiency (A+++ energy rating on selected models) reduces electricity consumption and operating costs during the year.
-
Engineered for residential environments with low operating noise, making the system suitable for urban and suburban developments.
-
Integrated controller with remote monitoring and smart scheduling enables users to optimise comfort, improve energy efficiency and monitor system performance.
-
EnergyBox™ AIR simplifies the installation process through a factory-integrated hydraulic interface, reducing onsite labour, commissioning time and installation risk.
