Product detail

Charnwood SLX 45i & 45fs

The SLX 45 has identical looks and features to that of the SLX20, but features a thermostatically controlled, integral boiler that delivers a heat output sufficient to power 8-9 radiators and ample hot water. Because it is fitted with a water temperature sensitive thermostat, heating controls can be fitted, to give heat precisely when and where it is needed. It is available as an inset or freestanding appliance with a choice of a matt paint finish or gloss black vitreous enamel.
