Do you find yourself wishing that the Alpine™ line included larger sizes so you could heat shopping malls, high schools and hospitals with it Wish no more The Alpine™ line now includes 399, 500, 600, 700 and 800 mbh models so you can efficiently heat just about any structure. The new models feature the ease of service and installation you've come to expect from the Alpine™. In a commercial setting, the big Alpine™ sizes have a lot to offer where other boilers might fall short. The Alpine™'s small footprint allows even the largest models to pass through a standard doorway and you can stack them two high in small mechanical rooms where lots of capacity may be needed. For simple lead-lag operation, use an RG-45 phone cord to link Alpine™ units together.
