Abstract
A heat exchanger is formed of a pair of concentrically arranged cylindrical shells, closed at each end to define a chamber through which water can pass. A combustion element extends into the inner shell from one end along the axis thereof and is connected to a source of heat such as a gas/air mixture which ignites in the combustion element causing the radiation of heat outwardly from the combustion element. The inner shell is formed of a corrugated wall which may be formed as a single corrugation comprising a continuous helix along the length thereof or a plurality of undulations extending along the length of the cylinder.
