Logano GB125 oil condensing boiler - Technical specifications are subject to change without prior notice.

Product description

The boiler is a condensing boiler with oil combustion and
modulating boiler water temperature control that can
operate in open or balanced flue mode. The respective
flue system determines the mode of operation.

The boiler comprises:

•

Control unit

•

Boiler casing

•

Boiler block with thermal insulation

•

Boiler door

•

Burner

•

Heat exchanger system

The control unit monitors and controls all electrical boiler
components.

The boiler shell prevents energy losses and acts as a si-
lencer.

The boiler block transfers the heat generated by the bur-
ner to the heating water. The insulation prevents energy
losses.
