Combi boiler for residential use

From: A. O. Smith

The ProLine XE Combi Boiler from A.O. Smith aims for instantaneous response time with its pre-heat and domestic hot water response modes that enable the unit to deliver hot water almost instantaneously during frequent use cycles. For space heating, the combi-boiler offers energy savings by immediately stopping nonheated air from circulating when switching from space heating to domestic hot water mode.
