Boiler
The boiler is the heat ge ne ra ting part of a hot water mac hi ne. It consists of a labyrinth-constructed
tube coil, which encloses the combustion chamber.
The tube coil is enclosed by a dou ble con tai ner with boilerjacket, bottom, and top in a sandwich con-
struction, between which the combustion air is pressed 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.
