1. A water heater, comprising:a burner section for generating heat; a fuel inlet section for supplying fuel to the burner section, said fuel inlet section being connectable to a fuel source; a gaseous fuel control system connecting the burner section and the fuel inlet section; said gaseous fuel control system including a conduit along which are located (i) a valve, located subsequent to flow to said fuel inlet section; (ii) an orifice received in said conduit and in communication with the valve and having an effective diameter in the range of about 0.010 inch to about 0.030 inch; (iii) a port defined by said conduit and in communication with the orifice and having an effective diameter in the range of about 0.010 inch to about 0.030 inch; whereby fuel flowing from the fuel inlet section to the burner section may be controlled; a heat exchanger, said heat exchanger having an inlet section and an outlet section whereby water may flow through the heat exchanger; and wherein the burner section is located proximate to said inlet section of said heat exchanger for heating water passing through the heat exchanger; a conically-shaped interior coil conduit, said coil having a first end and a second end, the diameter of said coil decreasing along with the coil axis from said first end to said second end; a cap located proximate said second end of said conically-shaped interior coil; and, an exterior coil conduit, located about said interior coil conduit and in fluid communication therewith.
