How Does A Gas Water Heater Work? 

Gas water heaters are a popular option among a considerable number of homeowners in Atlanta. While they cost more upfront than electric water heaters, gas water heaters are easy to install, cheaper to operate, and heat more water per hour compared to electric water heaters. If you’re considering installing a gas water heater in your home or business, it’s important to understand how they work so that you can get the most out of your unit. Besides, you’ll need to hire an experienced plumber in Atlanta to help you with installation. 

Let’s look at how gas water heaters work.

A gas water heater is made up of several components, including a storage tank (for tank-type gas water heaters), insulation, gas control valve, gas burner, igniter, gas combustion chamber, thermocouple, anode rod, dip tube, gas manifold, drain valve, hot water outlet, and many more.

How Tankless Gas Water Heaters Work

Tankless gas water heaters heat water directly without using a storage tank. When you open a hot water tap, cold water is drawn into the water heater and a sensor activates the gas burner upon detecting water coming into the heater. The gas burner fires and the heat exchanger instantly warms the water you need. The heated water travels directly from the heater to the faucet or appliance, rather than a storage tank. When you turn off the hot-water tap, the water heater shuts down. Tankless gas water heaters are equipped with a thermostat that regulates the amount of gas released through the burner to maintain a pre-set water temperature. Basically, a tankless gas water heater sits idle until you open a hot-water tap.  

Tankless gas water heaters boast greater energy efficiency since they only heat water when it's' needed. This is one of the reasons they are becoming increasingly popular among homeowners and businesses in Atlanta.

How Tank-Type Gas Water Heaters Work

These gas water heaters have a storage tank whereby cold water flows into the unit, and a gas burner located at the bottom of the tank heats the water. The heated water is then stored in the tank until it’s needed. Tank-type gas water heaters are also equipped with a thermostat which keeps the temperature in a water heater at the desired level. When this device detects temperature below the level that you’ve set the unit at, it will turn the gas on and reheat the water until the desired temperature is achieved. This water heater has a pressure-relief valve that relieves excess pressure in the storage tank. When you open a hot-water tap, heated water is pumped from the tank to the faucet or appliance through hot-water supply pipes.
