FAQ:

Q: What is the warranty for a water heater?

A: Most water heaters come with a standard 6-year warranty. Bradford White and Rheem , both plumbing professional choices, offer full term warranty on both the tank and components. In contrast, if you read the warranties on cheaper units, the warranty is for the tank, but parts are covered for just 1 year.

Q: Why does water heater have two thermostats?

A: Thermostat Issues. The most common reason that the water in the tank is getting too hot is that there is an issue with the water heater’s thermostat. Electric water heaters have two thermostats, one on the upper heating element and one on the lower one.

Q: Does a water heater have a thermostat?

A: Nearly all residential hot water heaters have two thermostats and two heating elements. In normal, low water usage conditions, the lower element is the one doing the work. It is only under high water requirements that the entire tank will cool down; the lower element will then shut off and the upper element takes over the load.

Q: How hot is a water heater?

A: First check to see what the temperature setting is on the thermostat. When water heaters are installed, they are usually set to 140 degrees Fahrenheit. The optimal temperature setting should be 120 degrees Fahrenheit.
