Water Heaters

Training Course

This course provides students and practicing technicians with the information and knowledge necessary to understand typical operation of both gas and electric water heaters. It is full of color illustrations and includes end of course review questions that provide students and practicing technicians with the information and knowledge necessary to accurately and safely install, service, and maintain storage-type water heaters.


After completing this course, the learner should be able to:

  • Recognize safety-related issues when working on gas or electric water heaters.

  • Describe the most common water heater ratings and sizes.

  • Describe how to calculate a water heater’s first hour rating.

  • Identify and discuss components common to both electric and gas water heaters.

  • Describe the typical operation of gas water heaters and the gas-related components.

  • Describe the typical operation of electric water heaters.

  • Explain typical routine maintenance procedures for gas and electric water heaters.

  • Discuss troubleshooting common faults for both gas and electric water heaters.

    • A course completion certificate will be issued upon completion.

    This course will also prepare learners for the HVAC Excellence Water Heaters Certification Exam (not included with course.)
