When it comes to boiler room efficiency, even a small upgrade can lead to major, long-term savings. That\u2019s what happened at a central plant in Maryland, where a simple retrofit led to over a decade of energy and cost reductions.<\/p>\n\n\n\n
The project started with the facility installing a Variable Frequency Drive (VFD) on an aging linkage boiler, paired with Preferred\u2019s PCC-III Utility Saver Controller. Forced draft fan motors typically run at full capacity regardless of system demand, wasting power. But with a VFD, the fan speed automatically adjusts to match real-time load, reducing electrical consumption dramatically.<\/p>\n\n\n\n
Think of it like driving a car: you don\u2019t floor the gas pedal and control speed with the brakes. You press the gas only as needed. The same logic applies to your boiler\u2019s energy use.<\/p>\n\n\n\n
Using Preferred\u2019s Energy Saver Payback Analysis Tool, the facility calculated a two-year payback period, after which the savings kept growing. A decade later, the system continues to deliver significant reductions in electricity, fuel consumption, and emissions, thanks to proper tuning through the Utility Saver controller.<\/p>\n\n\n\n
