Commercial Water Heaters

A commercial unit will be made of heavier components than a residential, commercial units are designed to run on a much more continuous basis than a residential one.


A commercial heater will also have the ability to set the water temp to a higher set point. A tempering valve would then be used to limit the temp going to the users.


The other thing you will find as you compare is that commercial heaters are available in much higher BTU rating than the residential, which gives you a higher gallon per hour availability.


The commercial units have larger burners and are constructed from a heavier metal. Some models are ASME rated which have an even thicker shell and made to strict specifications, and testing.
