Proper Commercial Water Heater Sizing
Commercial water heaters are typically rated using FHR (First Hour Rating). The First Hour Rating represents the amount of hot water a system can produce during the first hour of heavy use.

FHR is determined by two key factors:
- BTU input
- Tank gallon capacity
For example, a common commercial unit may be rated around:
199,000 BTU / 93 Gallon Capacity
The exact specifications for your existing system can be found on the manufacturer’s label (rating plate) located on the upper portion of the water heater.
