A. O. Smith commercial gas heaters are built to handle the constant hot water demands of restaurants, hotels, office buildings, and laundry facilities. When your business depends on reliable hot water, you need equipment that won't let you down.

Our Cyclone® series has been the go-to choice for over 30 years because it just works. You get 95% or higher thermal efficiency, leading to lower operating costs month after month. Models range from 60-gallon units to massive Cyclone® XL systems with 1 million BTU capacity, so there's a size that fits your needs. AIQ® adaptive gas technology automatically adjusts to your gas quality throughout the heater's life. You get consistent performance without constant adjustments, which means fewer service calls and less downtime for your business.
