Abstract: A direct contact, water heating column furnace for producing non-corrosive, drinking-water-quality heated water comprising a body or shell having at least an upper, heat exchange and stripping compartment and integrally formed and in-line therewith a lower compartment. A grating separates the integrated two compartments and a plurality of heat absorbing and transfer bodies, such as for example, Paul rings, are positioned within the upper compartment on top of the grating. A greater amount and depth of heat absorbing bodies are provided than would be needed merely for heating in order to also strip the water of substantially all its free oxygen to eliminate the corrosive effects of CO.sub.2 presence. Cold water is introduced into the furnace by a spray positioned over the heat absorbing bodies with the water running into the lower compartment as it is heated and oxygen-stripped by heating means. The heating means operates at a relatively low temperature free of intense hot spots to avoid NO.sub.
