Condensing boilers

Luna AIR

Combi condensing boilers for outdoor installation

Residential
Outdoor solutions

Luna Air is the range of condensing boilers for outdoor wall-hung and built-in installations, ideal in all situations where available space does not permit indoor installation.


A built-in installation is possible (with connection kit available as optional) to save space on small balconies or if there are any aesthetic constraints, being almost invisible.


Remote digital control panel supplied with the boiler for an easy comfort management.


Thanks to the 1:7 modulation range, the boiler’s output varies in line with system demands, with resulting savings on gas consumption and energy costs.
