Gas Water Heaters

Gas water heaters come in both tanks as well as tankless type. The tank gas water heaters are less costly than the tankless gas water heaters. The gas models work on the principle of convection where the heat rises up. The cold water in the gas tank water heater is heated by various technical appliances. The cold water is supplied through a pipe in the tank which goes to the bottom of the tank. The gas burner heats the bottom water, as the water gets warmers it rises up which is removed or used by the hot water outlet for various purposes.

Components of gas water heaters and how it works?

The main components of a gas water heaters are gas shut off valve, cold water shut off valve, gas supply line, main water line, temperature or pressure relief valve, gas burner drain valve, water line, dip tube,  etc. The initial installation, purchase price and operating cost of a gas water heater is lower than the electric gas water heaters. Tankless gas water heaters have no storage tank but apply the same connection principle. There is no standby operation hence it is energy efficient saving lots of energy in heating water. The gas burner starts working when the flow sensor is activated. The heat exchanger inside the tank heats the cold water that surrounds it. There is a venting system that lets all the gases to move out. The dip tube is longer than the hot water pipe. The reason is the warm water rises and the cold layer is on the top hence to remove the hottest water hot water outlet pipe is shorter than dip tube. The gas temperature regulator is fitted on the side of the water heater. It has a thermostat to check and test the temperature of the water heater. This regulator is a magical element that turns on and off the gas burner when required as per the set water temperature. There is a vent pipe that removes all the combustion gases through exhaust flue. The exhaust is situated at the centre of the tank through which gases are released and also it helps in exchanging heat to warm the water. The outer body of the gas tank water heater is made up of stainless steel. Insulation between the inner tank and outer body prevents heat loss.

The gas water heaters work on natural gas or liquid propane. The gas is supplied through a pipe which has a gas shutoff valve which must be known to all the users. As it is important to stop the gas supply in emergencies or during maintenance. The gas regulator is the medium through which gas is passed on to the gas burner assembly. The gas assembly has two important elements – Pilot light and gas burner. A thermocouple is included in the pilot light which has a flame sensor which acts as a safety measure. A pilot light is a flame used to ignite the gas burner. When gas water heaters are lit the gas goes to the burner but if there is no pilot flame, it may cause serious explosion and mishap. Hence the thermocouple prevents gas from leaking by shutting the gas valve.
