How it works

Step 1:
Coldwater enters through a pipe at the bottom of the tank.

Step 2;
A gas burner located under the tank begins to heat the tank.

Step 3:
The hot exhaust gases from the burner travel up the side of the tank further heating the water to the desired temperature.

Step 4:
The hot water progressively rises to the top of the tank. When a tap inside the home is turned on, the hottest water then exits at the top of the tank where it flows to the user’s location.

Step 5:
To ensure the water stays at the right temperature, a thermostat constantly measures the water temperature and turns the burner on or off as needed.
