Hot Water System Controllers – Smart Upgrades for Energy Savings
Improve Comfort, Cut Costs – With Utility Rebates from Peoples Gas and Nicor GasOutdated boiler and hot water pump systems often run constantly—wasting energy and driving up your utility bills. Advanced system controllers optimize performance by ensuring hot water and heating are delivered only when needed, reducing energy waste and improving system reliability.
With support from Peoples Gas and Nicor Gas rebate programs, installing energy-efficient controllers is more affordable than ever—and in many cases, eligible buildings may receive rebates that cover a significant portion of the cost.

What Are Hot Water System Controllers?
Controllers are smart devices that manage how and when hot water and heating systems
operate based on real-time demand. Ideal for multifamily and commercial buildings, these
devices help prevent unnecessary cycling and overheating.
Common applications include:
-
Boiler Controllers – Adjust firing rate and runtime to match building heating demand
-
Hot Water Pump Controllers – Control recirculation pumps for domestic hot water based on occupancy or usage patterns
-
Temperature Sensors & Timers – Deliver heat or hot water only when and where it's actually needed
Benefits of Installing Controllers
-
Lower Energy Bills – Reduce gas and electricity use by eliminating unnecessary runtime
-
Increased System Lifespan – Reduce wear and tear on pumps and boilers
-
Improved Comfort – Provide steady, on-demand heating and hot water without overheating spaces
-
Automated Efficiency – Optimize performance without manual adjustments
-
Utility Rebates Available – Nicor and Peoples Gas may cover part—or much—of the installation cost
Who Should Consider Controller Upgrades?
You may benefit from installing advanced controllers if:
-
Your building uses hot water boilers or recirculating pumps for domestic hot water
-
You’ve noticed energy waste, overheating, or pumps running 24/7
-
Your property is located in a Nicor Gas or Peoples Gas service area
-
You manage a multifamily, mixed-use, or commercial property
