- High seasonal efficiency, with an SCOP of up to 6.22
- Ultra-quiet outdoor operation from 16 dB at 5 metres
- Compatible with underfloor heating and radiators, to flow temperatures of 75°C
- Natural R290 refrigerant with smart home energy integration
Key benefits
Everything you need in one system
Exceptional efficiency
A seasonal efficiency of up to SCOP 6.22 keeps running costs low right across the heating season.
Ultra-quiet operation
From 16 dB at 5 metres — discreet enough for dense neighbourhoods and tight boundaries.
Designed for modern homes
Architectural styling and concealed connections let the unit sit comfortably against premium properties.
Radiator and underfloor ready
Flow temperatures up to 75°C make it a genuine retrofit option onto existing radiators.
Intelligent zoned control
Room-by-room comfort across up to 18 zones, with weather-adaptive smart controls.
Heating and cooling in one
Year-round comfort from a single reversible system running on natural R290 refrigerant.
Best fit applications
The right heat pump for every build
From energy-efficient new homes to complex retrofits and light commercial installations, Kronoterm heat pumps are engineered to deliver reliable performance wherever they are installed.
Ultra quiet operation
Barely there, by design
Advanced compressor mounting, an acoustic housing and an intelligent night mode bring outdoor sound pressure down to as little as 16 dB at 5 metres — helping installations pass permitted development noise limits and keeping neighbours happy.
MyDesign
Six finishes, one silhouette
NERO, ANTHRACITE, CORTEN, INOX, OLIO and NEBBIA — a palette of premium finishes that lets the same award-winning unit answer to render, brick, timber or stone without an enclosure to hide it.
Smart control
Comfort on autopilot
LoRA Room Control measures and adjusts heating individually for up to 18 zones, while Multi-Source Enabled technology coordinates solar, pool heating and back-up sources so surplus generation is stored as heat rather than exported.
