The search for new energy sources has a fundamental importance concerning better quality of life for the mankind. Looking for a substitute for the existing pollutant fueled heating equipment, the Hydrogen Group of the Federal University of Paraiba (Brazil), has studied the application of hydrogen to this purpose. This work shows performance tests realized with a convective commercial heater exchanger, adapted to be fueled by hydrogen and applied for the environmental heating. The study also compared its gain and efficiency using butane. The results showed that the commercial heat exchanger adapted for hydrogen has a high gain and efficiency taking into account fuel consumption and that can be improved if the suggested alterations are implemented.
