Common Water Heater Terminology
Thermal expansion
Water heated inside the water heater will expand. This process is known as thermal expansion and causes the water heater to expand and contract or for the excess pressure to be pushed back into the cold water piping system potentially causing drippy leaky faucets and tub shower valves. the best explanation is that a 40-gallon water heater holds 40 gallons of water, when heated the 40 gallons expands to roughly 42 gallons when heated.

Water Heater Drain Valve
A valve is located at the bottom of the tank-type water heater to allow a water hose to be hooked up and the water drain after the electricity or gas has been turned off.

Water Heater Supply Valve
The valve located at the top of the water heater on the cold water side stops the flow of water to the water heater.

Expansion Tank
2-gallon bladder tank pressurized with air that allows room for heated water to expand safely without damage to the plumbing system.

T&P temperature pressure relief valve
Located on the top or on the side at the top of a tank-type water heater to relieve pressure caused by excessive heating of water. This device keeps the water heater from exploding in the event there is a malfunction.

Overflow pan
A pan with a drain fitting catches water that leaks from the water heater and allows the water to drain.

Supply line
Connection piping from the water piping system to the water heater, must allow means of disconnection and possess di-electric properties to protect dissimilar metals.

Dielectric Unions
This means disconnecting the water heater from the water piping system that contains physical separation between dissimilar metals to prevent electrolysis.

Corrosion is caused by natural electrical currents of dissimilar metals.

Flue Pipe
Gas water heaters have an exhaust flue pipe to convey the exhaust from the burner out through the roof. The water flue must be installed properly to prevent Carbon Monoxide gas from leaking into the home.

Gas Control Valve
Gas water heaters operate by means of a temperature-sensing gas control valve. The gas control valve controls the temperature by turning the gas on and off to the burner.

Thermocouple / Flame Sensor
The device converts the heat from the pilot light to electrical current allowing the gas control valve to be switched on and off to safely heat the water.

Hot Water Recirculation System
Recirculates water from the hot water piping back to the water heater to be reheated and delivered to the point of use providing an instant hot water effect at each faucet. Hot water recirculation systems come in two styles and both require a pump to push the hot water to the water heater.
