Luna Duo-Tec E

Condensing boilers

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

Residential

Wall Hung

The range of Luna Duo-Tec E condensing boilers is characterized by long term reliable performance.

The 1:7 modulation means efficiency and savings thanks to the reduction of boiler on/off cycles.

A Factory made hybrid system can be created combining a Baxi split or monobloc heat pump.
