Traditional residential and industrial furnace systems convert the chemical energy of liquid and gas fuels into thermal energy and, in some earlier applications, also into electric energy. This process is driven by a burner specifically designed and built. Often these systems operate at high temperatures, high pressures and relatively lower efficiency levels. The field of present invention generally relates to furnaces that combine the fuel production to the both thermal either electrical energy production. More particularly, the present invention produces a combustible gas that, within the internal workings of the present invention, and can efficiently be burned without the production of high levels of pollutants, at relatively lower temperatures and pressures. The foregoing characteristics, along with the limited size of the elements needed to practice the present invention, make it conducive for use as and in connection with, among other things, residential furnaces and other heating systems, including, for example, heat exchangers and residential hot water tanks. In short, the present invention involves the production of a combustible fuel gas, thermal and electric energy. This production is accomplished through the interconnected use of water electrolysis, catalysts, storage means, regulation, and mean of reusing materials to increase production efficiencies.
