A. O. Smith Introduces ProLine® XE Combi Boiler

December 12, 2017

ASHLAND CITY, Tenn. (Dec. 12, 2017) – A. O. Smith, a leading manufacturer of hot water systems for homes and businesses, will launch the ProLine® XE Combination (Combi) Boiler to deliver immediate hot water and comfortable space heating for homes. With its service-friendly compact design, the combi boiler offers professional contractors easy installation, set-up and maintenance in addition to a multitude of other benefits.

Available in early 2018, the ProLine XE Combi Boiler is engineered with residential building professionals in mind. By moving critical components, such as the built-in circulator, to an easily accessible location within the unit, service and maintenance are dramatically simplified. The combi boiler’s user-friendly interface—featuring a backlit LCD display that provides text-based diagnostic information—is one of the product’s leading differentiators, according to David Chisolm, vice president of marketing at A. O. Smith.

“The combi boiler’s set-up wizard will help simplify programming parameters for contractors, removing the need to interpret system codes and reducing the overall time to install or adjust the unit,” said Chisolm. “Homeowners will also appreciate its best-in-class energy efficiency, reliability and space savings—it’s small enough to fit in a closet or small room.”

Available in 110,000, 150,000 and 199,000 Btu/hr. models, the ProLine XE Combi Boiler can deliver up to 4.8 gallons of hot water per minute—the highest capacity in the combination boiler category. The product features outstanding energy-saving performance with 95 percent Annual Fuel Utilization Efficiency (AFUE) and a 10:1 turndown ratio. Further enhancing energy efficiency, the combi boiler features an air handler interlock that immediately stops non-heated air from circulating when it alternates from space heating to domestic hot water mode.

Homeowners can rely on the combi boiler to provide on-demand hot water in any season or climate. Its pre-purge function allows the unit to re-ignite almost instantaneously during frequent on/off use cycles, like hand washing dishes. Its pre-heat function keeps the boiler and brazed heat exchanger at a pre-determined temperature, reducing response time to bring domestic hot water to temperature.

The ProLine XE Combi Boiler features a five-year parts and 10-year heat exchanger limited warranty. It is designed, engineered and assembled in the United States.
