Commercial water heaters are massive systems, built to provide hot water to hundreds or even thousands of people at any time. Despite their impressive endurance, however, they do break down eventually. No matter how well you take care of it, your commercial water heater will eventually need to be replaced. Once you can recognize that your water heater is nearing the end of its life, you can take steps to have it replaced by a professional. The following are some of the signs that you need to replace your commercial water heater.

Loss of Output

Everyone’s probably had that experience where their roommate or family member has used all the hot water in their home. Essentially, that’s where the demand for hot water outstrips the supply that the water heater has ready. Once exhausted, you’ll need to wait for the heater to heat more water. Commercial water heaters, on the other hand, are so large that you really shouldn’t ever experience a total exhaustion of the hot water supply. If it seems like your water heater isn’t providing as much output as it should, you should get it examined by a professional. It may mean that it needs to be replaced.


Water heaters deal with massive amounts of water, from the day they’re installed until the day they’re replaced. All of that water exposure means that eventual rusting is almost a guarantee. There are measures in place to protect your water heater from the effects of rust, of course, but they do not last forever. When your commercial water heater begins leaking, it’s a good sign that it will need to be replaced soon.
