ABSTRACT:
A combined liquid filtering and heating apparatus comprises a cylindrical filter section coaxially mounted on top of a water-jacketed combustion chamber section. Cold unfiltered water is fed through the filter section and a portion of the feed is directed through and is heated in the jacket. The feed water passing through the filter is heated to a lesser extent than the water passing through the jacket by heat transfer from the combustion chamber and a plurality of flues extending from the combustion chamber through the filter section. The filter medium may be sand, cartridges, bags or the like.
