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.
