In a continuous flow heater for fluids, in particular water, comprising a series of heat exchange tubes 25 heated by means of combustion gases rising from a gas or oil fired burner, corrosion of the tubes is minimized by preventing the condensation of the vapour in the combustion gases from forming on the tubes by means of a covering 29 of heat resistant and insulating resinous material of the phenol or epoxy type extending over that portion of the tube which would normally be at a temperature below the dew point of the combustion gases or extending over the whole length of the tube where particularly corrosive gases are experienced. The absorption rate of radiant energy may be further increased by mixing carbon black or powdered mica to the basic resin. The thickness of the coating may be uniform or of varying thickness diminishing from the inlet to the outlet in conformity with the increase in temperature of the fluid within the tube.
