Electric water heaters are heated by which element?

• A. Gas burner
• B. Solar panel
• C. Element
• D. Heat exchanger

Answer: (C)

Electric water heaters rely on an electric heating element inside the tank to heat the water. When the thermostat calls for heat, electricity flows through the element, which gets hot and transfers that heat to the surrounding water, raising its temperature. This direct conversion of electrical energy to heat is why the heating element is the key component in electric models. A gas burner would heat water in a gas-powered heater, not an electric one. A solar panel provides heat in solar water systems, often via a heat exchanger, but not through the electric element. A heat exchanger moves heat between fluids and isn’t the direct heat source in a standard electric water heater.
