degreasing and phosphation process before being lacquered and

burnt at 220°C.

HEATING BODY

The boiler heat exchanger is constructed from mild steel with welded

joints. It is hydraulic tested under a pressure of 4.5 bar (maximum

working pressure = 3 bar).

HEATING ELEMENTS

Immersion heaters, constructed from stainless steel Incoloy 800 and

mounted in the top of the boiler, provide the power source for the

Boiler.
