Limited Time Increased Rebates! Eligible applications must be submitted by March 31, 2025.
Saving energy and money is always important. Upgrading to new, high-efficiency gas heating equipment can help you do both. Discover our exclusive rebates for National Grid customers on gas heating and water heating equipment that save energy without sacrificing performance.
High efficiency furnaces can use less fuel to produce the same amount of heat, resulting in lower energy consumption and reduced costs.
Often referred to as a combi boiler, this highly efficient heating system provides both hot water and space heating from a single unit.
A condensing boiler recovers and reuses heat from combustion gases, reducing fuel consumption and increasing efficiency.
This equipment saves energy by circulating water from the main boiler through a heat exchanger in a storage tank, reducing usage.
Ensure the health of your gas furnace or boiler with a tune-up to optimize performance, improve efficiency, and prevent potential issues.
This device automatically controls the boiler water temperature based on outdoor weather so the heating system runs efficiently.
This smart device adapts to your preferences and optimizes heating & cooling efficiency, providing personalized comfort & savings.
ERVs & HRVs improve indoor air quality, save energy, and defend against allergens by replacing stale indoor air with fresh air.
