Red Seal Plumbing Practice Exam

Which of the following best describes an electric water heater?

1. One with a direct flame

2. One with a boiler

3. One with an immersion type element

4. One with a solar panel

The correct answer is: One with an immersion type element

An electric water heater is a type of water heater that uses electricity as its main power source. It typically consists of an insulated tank filled with water and an immersion type element, which is a heating element that directly heats the water. Option A and B are incorrect because they do not involve electricity as the heating method. Option D is incorrect because it uses a solar panel, which is not typically a common component of an electric water heater. Therefore, option C, one with an immersion type element, best describes an electric water heater.
