Gas alarm and detoxification heating systems

Claim 1

A gas monitoring and heating assembly which comprises an electrochemical reactor containing an anode and a cathode disposed therein for the electrolytic conversion of water into hydrogen and oxygen, means for recovering the oxygen from the electrochemical reactor and introducing it into the atmosphere, an oxygen room sensor operatively connected to the electrochemical reactor for controlling the generation of oxygen based upon the measurement of the oxygen content in the room, a water heater containing a burner, means for recovering the hydrogen from the electrochemical reactor and introducing it as fuel to the burner, cold water inlet means and hot water outlet means for introducing cold water to said water heater and recovering hot water from said water heater, said water being heated by indirect heat exchange with the heat generated from the burner, and heating means comprising a heating chamber which communicates with the atmosphere, heat exchange conduit means disposed in said heating chamber and connected to said cold water inlet means and hot water outlet means and blower means for blowing air across said heat exchange conduit means, whereby at least a portion of the hot water recovered from the hot water outlet means can be selectively introduced into the heat exchange unit means for heating the air from the blower means, said water with the heat removed therefrom being returned to the cold water inlet means, and a gas alarm operatively associated with the oxygen room sensor, said gas alarm being activated when the oxygen room sensor senses a reduction in the oxygen content of the room below a predetermined level.
