Businesses in Santa Monica depend on reliable hot water every single day from customer-facing hospitality spaces to behind-the-scenes operations. Water Heaters Only, Inc. provides expert service for commercial water heaters in Santa Monica, helping property owners and facility managers install, replace, and upgrade systems built for higher demand and long-term performance.
Commercial water heaters are engineered for commercial and institutional environments where hot water usage is frequent, consistent, and often simultaneous across multiple fixtures or tenants.
Choosing the Right Commercial Water Heater

Unlike residential systems, commercial water heaters are evaluated based on their First Hour Rating (FHR) the total amount of hot water the unit can deliver during its first hour of operation. This performance metric is influenced by:
- BTU input
- Tank volume
- Recovery rate
When replacing an existing commercial unit, matching the overall style of the tank is often helpful. However, the most important factors are ensuring the new system meets or exceeds the original BTU output and required FHR, so your business doesn’t experience shortages during peak usage.
Commercial Applications We Support in Santa Monica

Newer systems are designed to improve efficiency, reduce environmental impact, and comply with stringent air quality requirements, particularly important in coastal communities like Santa Monica.
