Straight Talk about Commercial Boiler Efficiency | Weil-McLain

Each boiler will cycle one-half to one-third less than a single boiler, thus increasing seasonal efficiency significantly. However, the key to maximizing efficiency with two or three commercial boilers is to be sure that each boiler is completely isolated from the others so that non-operating boilers will not be hot with system water.
