Gas heating device

A gas heating device comprising:

• a main body defining a combustion chamber, wherein the main body includes a base and a gas conduit carrying a combustible gas and extending through the base and connected to and in fluid communication with the combustion chamber;
• a catalyst disposed in the combustion chamber, wherein the catalyst is connected to the gas conduit;
• a heating coil providing electric thermal energy to heat the catalyst and disposed in the combustion chamber completely outside of the catalyst and adjacent to a side of the catalyst, wherein the heating coil includes a coil wire which is looped to form a plurality of loops, with the catalyst being of a cylindrical shape, and wherein the plurality of loops is coaxial to each other and is located outside of the cylindrical shape of the catalyst;
• a first conducting wire;
• and
• a second conducting wire, with the heating coil including first and second ends thereof respectively connecting to first ends of the first and second conducting wires, wherein the first ends of the first and second conducting wires and the heating coil are disposed in the combustion chamber, and wherein the first and second conducting wires extend through the base and each have an end disposed outside the combustion chamber.
