Condensing boilers

Duo-Tec Compact E

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

Residential
Wall Hung - compact

Duo-Tec Compact E has been designed 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 1:7 modulation of Duo-Tec Compact E means efficiency and savings thanks to the reduction of boiler on/off cycles.


To save space in the house, Duo-Tec Compact E can be installed also outdoors (with upper cover available as optional).
