Tank Type Gas Water Heater

The gas water heater consists of a sealed container. It is designed with a gas burner underneath.

Gas Burner

The pipe supplies cold water continuously into the tank. The water at the bottom starts warming slowly by a gas burner. Eventually, the water gets hotter. Water would start rising in the tank when a certain level is crossed by hotness.

Supply Line

As cold water is supplied regularly, so hot water remains in the upper level of the tank. Whenever you want warm water, the tank supplies it from its upper level.

The hot water discharge pipe is shorter than the cold water supply pipe because it reaches only the tank’s surfer level.

Using Regulator

A gas regulator controls the gas water heater, and a 5A regulator controls the gas burner to heat water as you want. The regulator is situated at the side of the tank.

It has a thermostat that helps you to know and monitor the temperature of the water. By thermostat, you can set and maintain the temperature as you desired.
