High Efficiency Furnace and Gas Boiler Rebates

Rebates of up to $750

Reduce your home heating costs with a high-efficiency natural gas furnace or boiler. You’ll enjoy clean, reliable heat and receive an instant discount of $35 on a boiler circulator pump or up to $750 when converting your existing non-condensing system to a condensing furnace or boiler when you install a qualifying natural gas furnace, natural gas boiler or a boiler circulator pump. A pre-verification inspection is required prior to installation to confirm eligibility.

Achieve efficiencies as high as 97 percent!

In most homes, heating is the single biggest energy expense. Replacing your old furnace, boiler or boiler circulator pump with new high-efficiency heating equipment can take a bite out of your energy costs, plus make your home more comfortable. Older furnace and boiler systems have efficiencies in the range of 56 to 70 percent. High-efficiency heating systems achieve efficiencies as high as 97 percent, converting nearly all the fuel to useful heat for your home. That can mean big savings!

Before you invest in a new furnace, boiler, or boiler circulator pump, make your home as energy efficient as possible. Improving insulation and sealing air leaks to stop heat loss may allow you to purchase a smaller, less expensive heating system. Our Home Energy Solutions program can help you identify and make energy-saving improvements that are right for your home.

To Receive Your Instant Discount on a Boiler Circulator Pump*:

  • Prior to purchase, confirm your system qualifies for the discount with your HVAC contractor, checking approved products list, or by checking the minimum efficiency chart below.
  • Have your licensed contractor provide a quote for qualified equipment from an EnergizeCT.com listed participating distributor that includes the instant discount.
  • Finally have your licensed contractor purchase and install qualified equipment from a participating distributor. It’s that easy!

Instant discounts are valid for UI residential customers who purchase and install* a qualifying:

  • Boiler circulator pump
