Luna Compact

Heating only and combi condensing boilers with a modern and compact design for new buildings and replacement

Residential

Wall Hung - Compact

Luna Compact is ideal for small to medium size apartaments and for all situations when saving space is important. The compact dimensions allow the boiler to be located in any housing, including a kitchen cupboard.

The 1:10 modulation of Luna Compact means efficiency and savings thanks to the reduction of boiler on/off cycles.

It is equipped with BaxiSPACE electronics for a smart integration of different products and technologies (for heating/cooling and hot water production) in a system with a simple management.
