Lochinvar has increased the thermal efficiency of its CREST condensing boiler to up to 96% for major commercial applications. The enhancements are available in six models from 2.5 to 6 million Btu/h. Lochinvar product-development engineers found more energy savings by manufacturing the unit with an upgraded combustion system and an updated 316L stainless steel heat exchanger. The CREST boiler has an improved modulating burner delivering a turndown ratio up to 20:1 and flexible flow rates up to 600 gpm to meet the needs of the largest commercial applications.
