PHNIX produces R290 indoor monoblock heat pump
18th April 2026
CHINA: Chinese heat pump manufacturer PHNIX has launched AirMono, an R290 indoor monoblock heat pump, specifically engineered for the European market.
AirMono offers a heating, cooling, and DHW solution that eliminates the traditional outdoor unit, and, according to PHNIX, solves the problem of limited space for millions of residential retrofits.
By utilising an indoor-mounted design with air ducting, the AirMono can preserve building facades while fitting comfortably inside kitchens, utility rooms, or garages. It can also connect directly to a user’s existing water tank, serving as the perfect indoor replacement for traditional gas or oil boilers. It perfectly combines functionality with aesthetics, allowing for a seamless, low-cost transition to green energy.
Boasting A+++ energy rating, PHNIX claims the AirMono qualifies for the UK BUS grant and qualifies for substantial BEG funding in Germany.
A special three-side quick-access design allows technicians to service core piping and electrical components without moving the unit.
Equipped with a gas separator and R290 leak detector, the system is said to rapidly detect leaking refrigerant and actively discharges it. One minute after startup, the system monitors refrigerant concentration in realtime; if values exceed preset thresholds, it triggers shutdown protection, and the fan adjusts to preset speed to vent refrigerant outdoors.
