The boiler is the heat generating part of a hot water machine. It consists of a labyrinth-constructed
tube coil, which encloses the combustion chamber. The tube coil is enclosed by a double container
with boiler jacket, bottom, and top in a sandwich construction, between which the combustion air is
routed into the combustion. An insulating material placed in the bottom of the boiler makes sure that
the inner bottom, among other things, is protected from superheating.
