Gas Water Heater Runs Constantly

Find out how to stop a gas water heater from cycling on and off all day. A gas water heater works like this: you set the temperature on the the thermostat; the gas comes on and heats the water to that temperature. Then the gas goes off until the water cools and the burner comes back on. The solution to this cycling effect is to put additional insulation around the outside of the water heater. However, be very careful not to cover the burner compartment or block the vent pipe.
