The water heater, or a geyser as it is more popularly called, has became a part of our daily lives. It is essentially a drum filled with water and equipped with a heating mechanism. A water heater's thermostat controls the temperature of the water inside the tank. Normally, you can set the temperature between 49 and 82 degrees Celsius.

The water temperature setting recommended by most manufacturers is between 49 and 60 degrees Celsius). This is hot enough to be efficient for household use, but not so hot that it can pose a risk of scalding. If there are children at home, it is wise to stay closer to the lower end of the range. The same technology is used for other water-heating appliances, like a dishwasher or a washing machine.

How water heaters work
The two types of water heaters that are commonly used are gas and electric ones. The choice depends on the price, availability of natural gas and the usage of hot water in a household. It could be used for cooking, bathing or and room heating.

Though electric water heaters are prominently used, a gas water heater is more cost effective. Gas heaters heat a tank full of water much faster then electric water heaters. Another point to be noted is that any problem with the power supply may directly impact the supply of hot water.

The gas water heater has a pilot light while the electric one doesn't. A gas water heater heats water by burning the gas in a covered burner at the base of the heater. The heater exhausts the produced heat into the dwelling space.

There are electric heaters that turn off when the load is high.
