Burnham Commercial offers a selection of system control packages to let you design modular/

multiple boiler installations based on heat use, fuel economy, and the desired level of automation.

Enjoy the peace of mind that comes with modular and multiple boilers. Multiple boilers can continue

to heat the building even while one is being serviced, and you won't have to worry about lost

efﬁciency due to short cycling during shoulder months.
