When considering a retrofit for efficiency upgrades, project engineers, facility managers, and energy teams are all being asked the same question: What’s the return?

To help answer that question, Preferred Utilities has developed the EnergySaver Payback Analysis Tool, a free, engineering-grade web application that calculates fuel, electricity, and emissions savings from combustion and fan system upgrades.

A Smarter Way to Justify Upgrades

Whether you’re upgrading a burner, adding an O₂ trim system, or modernizing fan controls with a Variable Speed Drive (VSD), the EnergySaver tool provides a snapshot of how those changes translate into measurable performance improvements.

By inputting your existing system data — boiler size, fuel type, O₂ levels, fan motor horsepower, and firing rates — and comparing it with your proposed upgrade, the tool automatically calculates:

• Fuel and electricity savings
• Annual CO₂ reduction
• Simple payback period and ROI
• Overall system efficiency improvements

In minutes, users receive a detailed analysis that can be included in proposals, capital requests, or customer presentations: replacing guesswork with data.

Built by Engineers, for Engineers

Preferred’s EnergySaver Payback Analysis Tool was designed by our in-house combustion and controls experts to reflect real-world boiler room conditions.
It accommodates a wide range of configurations, including:

• Natural gas, No. 2 and No. 6 oil, propane, and blended fuels
• Forced draft fan systems with optional VSDs
• Adjustable O₂ levels on both wet and dry bases
• Flexible firing rate breakdowns for partial-load operation

Every input drives a physics-based efficiency and energy-use model, resulting in accurate ROI projections for both retrofit and new installation scenarios.

For Project Engineers, Reps, and Facility Teams

For project engineers, the EnergySaver tool is a fast way to validate the economic case for upgrades.
For representatices, it’s a sales-enablement tool that helps you demonstrate the value of Preferred’s combustion and controls solutions, visually and quantitatively.
And for facility teams, it’s a practical resource to guide operational planning and sustainability reporting.

Continuing Our Legacy of Trusted Engineering

Preferred has spent more than a century engineering smarter, safer, and more efficient systems for critical facilities. The EnergySaver Payback Analysis Tool extends the tradition, combining our deep technical bench with modern digital tools that help customers, facility managers, owners, engineers, and everyone on the project team make informed decisions.

When it comes to efficiency, savings, and sustainability, we’re removing the guesswork so that you can move faster and with better information.
