FAQ:

Q: What are the parts of an electric water heater?

A: Components of a Water Heater. Electric and gas water heaters have a number of components in common, including the drain valve, the TPR valve, an internal anode rod, dip tube and pipes and fittings for hot water and overflow/pressure relief.

Q: What gas is in a water heater?

A: The gas valve on a water heater contains an electromagnet, which activates when heat from the pilot flame reaches the thermopile circuit. The activated electromagnet keeps the gas valve open, letting the gas flow into the main burner and pilot. When the pilot flame is out, the electromagnet deactivates, and the gas supply closes.

Q: Is my water heater broken?

A: Any type of unusual noise coming from the water heater is a sign of trouble. Typical noises of a broken water heater include creaking, whining or knocking. Noises are usually the result of sediment buildup inside the tank.

Q: What is a crossover water heater?

A: The Crossover Residential/Commercial Floor Water Heater is a revolutionary product and was designed to be the most highly efficient affordable residential tank type product in the industry. These models combine the flow capacity of a 50 gallon tank type water heater with the continuous flow feature found in tankless water heaters.
