Does the combustible materials storage requirement of a 3 foot distance apply to electric water heaters?

• A. Yes
• B. No
• C. Only in winter
• D. Only for apartments

Answer: (B)

The key idea is that the 3-foot distance for storing combustibles targets ignition sources. Electric water heaters do not burn fuel and do not provide a flame or direct ignition source during normal operation, so that specific 3-foot storage rule doesn’t apply to them. If you were evaluating a gas-fired or other fuel-burning appliance, the rule would be relevant because those appliances can ignite nearby combustibles. You should still consider other safety aspects around water heaters (like space for service and electrical or venting requirements for non-electric units), but the 3-foot combustible-storage requirement isn’t required for electric water heaters.
