Expert Installation, Replacement & Sizing Call (800) 833-4571
From growing commercial corridors to industrial zones and multi-unit housing, businesses in Riverside rely on dependable hot water systems to keep operations moving. Water Heaters Only, Inc. provides professional service for commercial water heaters in Riverside, offering installation, replacement, and system upgrades designed to handle higher demand and long term use.
Commercial water heaters are built for commercial, institutional, and light industrial applications, where hot water demand exceeds residential capacity and consistent output is essential for daily operations.
Understanding Commercial Water Heater Performance

Commercial water heaters are measured differently than residential units. One of the most important performance indicators is the First Hour Rating (FHR) the total amount of hot water the system can supply during the first hour of peak usage.
FHR is influenced by:
- BTU input
- Tank size
- Recovery efficiency
In replacement situations, installing a similar style tank is often a good starting point. However, ensuring the new unit meets the required BTU output and minimum FHR is critical to maintaining proper performance, especially during high-demand periods.
