There are few commercial buildings that can get along without a water heating system, even if just for their bathrooms. For many enterprises, the water heater is an essential component, such as in restaurants and throughout the hospitality industry. Commercial water heaters must be reliable, powerful, and have the water volume necessary to handle the needs of the building.
Eventually, all the strain placed on a commercial water heater will wear it down past the point where standard repairs and regular maintenance can do anything to reverse the deterioration. At that point, you’ll need the water heater (or one of the water heaters if your building relies on multiple ones) replaced.
