A commercial water heater should be installed in a commercial application.
When deciding whether to install a residential or commercial water heater in a commercial application, there are important factors to consider.
Commercial water heaters contain components that are designed to operate at peak performance 24 hours a day/7 days a week. Residential water heaters are designed to operate at peak performance approximately 2 hours in the morning and again 2 hours at night.
Commercial water heaters also offer many more options including, tank size, incoming BTU rating, electrical voltage and phase to name a few. Here are a few of the differences!
Water heater voltages:
A residential water heater can have incoming power source of either 120 volt or 240 volt.
A commercial water heater can have incoming power source of either 120 volt, 208 volt, 240 volt, 277 volt or 480 volt.
Water heater electrical phase:
A residential water heater is single phase only
A commercial water heater can be either single phase or 3 phase.
Water heater warranties:
Residential water heater warranties vary depending upon the manufacturer and whether the water heaters power source is gas, electric or solar. Concerning residential water heaters, the warranty extends only to the original owner.The heater must also be installed according to local codes and the installation site must usually be within one of the 50 states of the United States. Note: Allowed installation location can vary depending upon manufacturer.

Commercial water heater warranties are pretty straight forward with a 3 year warranty for tank leakage and a 1 year warranty for parts. Some manufacturers offer an extended warranty for certain commercial water heater models..for a price! The heater must also be installed according to local codes and the installation site must usually be within one of the 50 states of the United States. Note: Allowed installation location can vary depending upon manufacturer.
When considering whether to install a Commercial or residential water heater in a commercial application, the warranty must be considered.
Please keep in mind that the full residential water heater warranty is only effective if the residential water heater is installed in a single family residential application.
Therefore, if a residential water heater is installed in a commercial application, the water heater tank warranty is reduced to one year and the water heater parts warranty is reduced to one year.
Always consult with the appropriate code agency and Plumbing technician to determine whether to install a Commercial water heater or residential water heater.
