Modern day natural gas water heaters come in several different sizes and brands. Typical capacities are 30, 40, 50, 75, and 100 US gallons. Water heaters are needed to provide enough hot water to take showers, wash and sanitize your clothing, and sanitize your items in the dishwasher. Residential water heaters are usually set to 110-120 degrees fahrenheit but can produce higher hot water temperatures if needed. As the cold water enters into your home, it makes its way to the cold water inlet plumbing connection of your water heater. Water heaters are basically a tank filled with water and are equipped with a heating mechanism that is located at the bottom of the tank.
