Triad Boiler Systems

TRIAD Boiler Systems TRIAD Boiler Systems began almost 85 years ago manufacturing hot water heaters and hydronic heating convectors. The company soon expanded into the production of Hot Water Boilers for commercial radiant heating applications. Today, TRIAD continues this tradition by manufacturing Premium-Quality Commercial, Packaged Hot Water and Steam Boilers.


These modular units can be fired sequentially, based on heat-load requirements. With the use of commonly recognized, off-the-shelf controls and burners such as Honeywell, Powerflame and Riello, replacement parts are easy to obtain.


Commercial Modular Boilers of All Types TRIAD Hot Water and Steam boilers use a steel firetube design with inputs ranging from 210,000 to 2,000,000 Btu's. Multiple units can be operated via a control panel to produce many millions of Btu's. All TRIAD models from 600,000 Btu's to 2000 Btu's carry an Underwriter's Laboratories (UL) listing.

Triumph T-399

Triumph T-399

The Triad Triumph is a fully packaged condensing boiler. This high efficiency, low-NOx package represents the state-of-the-art in boiler design. The T-399 boiler is certified to 91.7% efficiency based on ANSI Z21.13. In keeping with the design philosophy of our conventional boilers the Triumph is designed to fit in very small spaces allowing for easy installations. Maximum firing rate is 399 MBH. The Triumph can be operated in either a condensing or a traditional non-condensing application. The sealed combustion unit allows for many venting options providing for a variety of jobsite installation solutions.

Design: The heart of the Triumph is a robust cast aluminum sectional heat exchanger. This proven technology has been utilized in European designs for over thirty years. The cast aluminum sections are impervious to corrosive condensate and is protected against thermal shock. The key to the longevity of this boiler is the use of an advanced aluminum alloy that makes an oxide layer without pitting. This approach allows for the construction of a boiler that can withstand the corrosive attack of condensed flue gases for years of reliable operation. This modern design has also eliminated the need for the push-nipples and gaskets that were a frequent maintenance issue on older technology cast iron designs. The heat exchanger is supplied with a five-year warranty.

The integral mesh burner provides for high combustion efficiencies and a high turn-down ratio while providing Low-NOx operation.

Safety: The fully packaged Triad Triumph is supplied with industry standard safety controls on the boiler that results in a very safe and secure package.
