Also called storage water heaters, these consist of a cylindrical vessel/container in which water is kept continuously hot and ready for use. Typical sizes for household use range from 20 to 100 gallons. These may use electricity, natural gas, propane, heating oil, solar, or other energy sources. Natural gas heaters are most popular in the United States, since the gas is often conveniently piped throughout cities and towns and currently is the cheapest to use.
Temperature Pressure Relief Valve
The name is Temperature Pressure Relief Valve (TPR valve). This safety valve releases water (and thus relieves pressure) if either the temperature or pressure in the tank gets too high. These valves are very important. Water heaters can become bombs if the pressure gets too high and these valves fail to work.
