Heating apparatus is described comprising: means defining a heating chamber; a burner for producing a flame within the chamber; heat exchanger means including a plurality of tubes extending within said chamber, each of said tubes having an inlet and an outlet for the passage of a fluid therethrough, and having a surface disposed to receive radiant energy from a flame produced proximate thereto by said burner; and means, supplied separately from said burner, for introducing a gas into said chamber and for so directing the flow thereof as to sweep said energy-receiving surfaces of said tubes so to prevent substantially contact of said surfaces by any deleterious substances that may be contained in the burner flame; whereby radiant energy from such a flame may be used to efficiently heat a fluid passing through said tubes, and said tubes may be protected from deleterious substances therein by gas from said means for introducing and directing.
