ABSTRACT:
A catalytic fluid heater formed of a number of nested fluid heating chambers spaced from one another to provide therebetween a heating zone having a chimney effect such that a mixture of fuel gas and air is caused to flow through the heating zone from the bottom to the top thereof. A catalyzed surface is disposed in contact with the walls of adjacent ones of the fluid heating chambers. A fuel gas, preferably hydrogen, is delivered to the heating zones, mixed with air and combusted on the catalyzed walls. The combustion product, in such cases, is primarily water vapor, so that external venting is not required.
