3. Energy factor - Wikipedia

   en.wikipedia.org/wiki/Energy_factor

   Hot water is drawn in six equal draws totaling 64.3 gallons, and a standby period of 18 hours follows. The energy factor for residential water heaters is determined using the results from the 24-hour simulated use test. During the test 64.3±1.0 gallons of water are drawn from the water heater in six equally spaced draws that begin one hour ...

   en.wikipedia.org/wiki/Heat_trap

   Right: Circulation of hot water is inhibited by the loop in the pipe. Heat traps are valves or loops of pipe on the cold water inlet and hot water outlet of water heaters. The heat traps allow cold water to flow into the water heater tank, but prevent unwanted convection and heated water to flow out of the tank.

5. Pilot light - Wikipedia

   en.wikipedia.org/wiki/Pilot_light

   In natural gas furnaces, water heaters, and room heating systems, a safety cut-off switch is normally included so that the gas supply to the pilot and heating system is shut off by an electrically operated valve if the pilot light goes out. This cut-off switch usually detects the pilot light in one of several ways:

   However, Illinois has very limited crude oil proved reserves that account for less than 1% of the U.S. total reserves. Residential heating is 81% natural gas compared to less than 1% heating oil. Illinois is ranked 14th in oil production among states, with a daily output of approximately 28,000 bbl (4,500 m 3) in 2005. [166] [167]

7. Electric heating - Wikipedia

   en.wikipedia.org/wiki/Electric_heating

   Portable immersion heaters may not have a control thermostat, since they are intended to be used only briefly and under control of an operator. For domestic hot water supply, or industrial process hot water, permanently installed heating elements in an insulated hot water tank may be used, controlled by a thermostat to regulate temperature ...
