The Proline XE Combi Boiler is the manufacturer’s latest offering in residential water and space heating systems. The unit can deliver up to 4.8 gallons of hot water per minute, provide an efficient 95 percent Annual Fuel Utilization Efficiency (AFUE), and is available in 110,000, 150,000 and 199,000 BTU/hr models. The combi boiler’s pre-purge function allows it to reignite almost instantaneously during frequent on and off use. A.O. Smith moved this model’s built-in circulator to an accessible location for simple installation and maintenance. A backlit LCD display provides text-based diagnostic information.

Manufacturer’s first dedicated combination design offers residential hot water and space heating from a single source. The ProLine® XE Combination (Combi) Boiler delivers 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.
