A. O. Smith has launched the ProLine XE Combination (Combi) Boiler to deliver hot water and space heating for buildings. With its compact design, the combi boiler offers professional contractors installation, set-up and maintenance ease in addition to multiple other benefits.
The ProLine XE Combi Boiler is engineered with building professionals in mind. By moving critical components, such as the built-in circulator, to an accessible location within the unit, service and maintenance are simplified. The interface of the combi boiler features a backlit LCD display that provides text-based diagnostic information.
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 product features 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 stops non-heated air from circulating when it alternates from space heating to hot water mode.
Building owners can rely on the combination 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. Its pre-heat function keeps the boiler and brazed heat exchanger at a pre-determined temperature, reducing response time to bring 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 U.S.
