83% combustion efficiencies throughout load range from total turndown (individual turndown multiplied by number of modules) to rated capacity. Where single boilers are installed, typical heating loads between 15% and 30% of design force frequent burner cycling, leading to significant heat loss and early equipment failure. Correctly controlled modular heating plants minimize cycling-related operating expenses. Modules appropriately sized for actual loads operate as necessary. Capacity required only for design conditions is reserved off/cold with zero heat loss.

Modular heating plant components are standard products of leading manufacturers which can be repaired/replaced by qualified servicemen. With one boiler out of service for inspection or repair, adequate capacity remains on line.

Individual modules can often be moved into place through existing elevators, doorways, and halls. Reduced burner noise levels increase plant location options. Modules can be grouped as desired to utilize available space. Modular groups (or banks) can be interconnected to increase total capacity and, when space is reserved, adding boilers to meet future expansion requirements is simplified.

Operating advantages insure rapid payback of any initial price difference between modular heating plants and single boilers. When new construction space/location requirements or costs associated with moving large replacement boilers into an existing buildings are calculated, modular heating plants are frequently competitive even before long-term savings begin to accumulate.
