Abstract
A boiler has a gas burner assembly and a heat exchanger positioned in a combustion chamber for heating water circulated through the heat exchanger by heat exchange with the combustion products. The performance of the heat exchanger is improved by rotating the heat exchanger to prevent formation of a boundary layer of cooler combustion products and/or a surface film of condensed moisture on the heat exchange surface.
