Abstract
A gas water heater with a tank for holding water including a gas valve mounted below the tank and in fluid communication with a supply of gas. A gas burner is fluidly connected to the gas valve. A first temperature sensor is mounted adjacent a lower portion of the tank and detects a temperature of the water in the lower portion of the tank, and a second temperature sensor is mounted adjacent an upper portion of the tank and detects a temperature of water in the upper portion of the tank. A control has inputs connected to the first and second temperature sensors and outputs connected to the gas valve. The control operates the gas valve in response to reading signals from the first and second temperature sensors such that water in the top and bottom portions of the tank stays within a desired temperature range.
