If your home has two water heaters and one fails, do you need to replace both?
Not necessarily.
The answer depends on:
• The age of both water heaters
• Whether they were installed together
• The condition of the second tank
• How the water heaters are connected
• How much hot water your home actually uses
If both tanks are the same age and already near the end of their expected lifespan, replacing both may prevent another failure and installation soon afterward. If the second water heater is newer and in good condition, there may be no reason to replace it.
Our latest blog explains what we look at before recommending one replacement or two.

When two water heaters were installed together but only one develops a problem, homeowners often wonder whether they should replace one or both. The answer depends largely on their age, condition, configuration, and your household’s hot-water needs.
