Sober design and reduced dimensions easily allow placing MAIOR EOLO X 28 in any room of your house. A small door covers knobs and buttons only, leaving the backlit liquid crystal display always visible, supplying information about the main functioning parameters and eventual error codes.

The advanced electronics allows the coupling of the boiler to the DIM (Multi system distribution manifolds ) and to the new modulating kits for the climatic thermoregulation, through which the boiler can be remotely controlled.

MAIOR EOLO X 28 is pre-arranged for connection to Immestor range (on specific kit optional) to produce DHW.

Certified to be installed indoor as well as outdoor in partially sheltered places thanks to the IPX5D electric protection, the boiler is supplied with a -5°C anti-freeze kit as standard.
