Combination Boiler/Water Heater Rebates

Get rebates from $425 to $675 on ENERGY STAR® combination boiler/water heaters

New Mexico Gas Company offers rebates from $425 to $675 when you have a licensed and insured participating contractor install a high efficiency, ENERGY STAR certified combination boiler/water heater with an Annual Fuel Utilization Efficiency (AFUE) equal to or greater than 92% and an Uniform Energy Factor (UEF) of .87 in your home.

Qualifying combination boiler/water heaters installed between April 1, 2020 and March 31, 2021 are available for rebates with our 2020 program. Rebate application and additional information is provided below.

Why choose a combination boiler /water heater?

  • Increased efficiency. Low running costs and energy efficiency since you are not paying to continuously heat water in a tank.
  • Unlimited Hot Water. With no water tank to heat up, combination boiler/water heaters can provide an unlimited supply of hot water on demand.
  • Space-saving design. Combining both a water heater and a central heating boiler into one compact unit saves you significant space in your home.

Rebates available. Save from $425 to $675 with a rebate on your purchase when you use a licensed and insured participating contractor. Only customers who receive natural gas service from New Mexico Gas Company, as evidenced by the New Mexico Gas Company residential customer account number, are eligible.
