The G10-3E Atwood water heater is designed to keep water temperatures up and delivers hot water fast. The Atwood G10-3E features include a high-temperature limit switch, thermostat and pressure relief valve that prevents problems before they happen. A simple flip of the switch from inside your coach lets you turn your water heater on or off. An extended cold water inlet tube from the G10-3E enables hot water to last 55% longer. The Atwood G10-3E holds up to 10 gallons of water per cycle and features a patented 'through-tube' combustion chamber that uses the pilot flame to help maintain water temperature, eliminating loss of heat energy.
