Lochinvar has expanded its CREST Condensing Boiler line with models tested in the elements and built for the outdoors. The CREST series now boasts six models, ranging from 750,000 to 2 million Btu per hour, designed and tested to endure strong winds, downpours and UV exposure. The option to install the unit outside adds more than 200 usable square feet to any space. The models feature a 96 percent thermal efficiency rating. The Outdoor CREST models come standard with the CON•X•US remote connectivity platform, which allows commercial facility managers and building owners to monitor and adjust equipment controls from a mobile app available on most smart devices.
