You must be a National Grid Massachusetts residential gas heating customer to be eligible for these rebates. Qualifying equipment installed between 1/1/14 and 12/31/14 may be eligible, pending availability of funds. All installations must be completed by a properly licensed contractor, with the exception of programmable thermostats, which may be self-installed. Rebate form and required documentation must be postmarked within 60 days of equipment installation and by 1/31/15 at the latest. Some restrictions may apply. Rebate offers are subject to change or cancellation without notice. Savings and energy efficiency experiences may vary. © 2014 National Grid

High-efficiency natural gas heating boilers and furnaces
Is your heating equipment more than 10 years old? Does it need frequent repairs? If so, it may be time to replace your heating system with a high-efficiency model. You could save up to 30% on your heating costs every year.
Furnaces are the most commonly used residential heating system in the U.S., and deliver heat through a duct system. Efficient furnaces often have a highly efficient blower motor known as an Electronically Commutated Motor (ECM).
Boilers heat your home by burning gas to heat water that circulates through radiators, baseboards, or radiant floor systems. Unlike furnaces, boilers don’t use a duct system. Features that improve boiler efficiency include electronic ignition, which eliminates the need to have the pilot light burning at all times, and technologies that extract more heat from the same amount of fuel.
Annual Fuel Utilization Efficiency (AFUE) is the measure of heating equipment efficiency, represented as a percentage. The higher the AFUE, the more efficient the heating system. An AFUE of 90% means that 90% of the energy in the fuel becomes heat for the home, and the other 10% escapes up the chimney and elsewhere. Want to go high-efficiency? Choose an AFUE of more than 95% for furnaces and more than 90% for hot water boilers.
Product Rebate
Natural gas hot water boiler ≥ 95% AFUE $1,500
Natural gas hot water boiler ≥ 90% AFUE $1,000
Natural gas furnace ≥ 97% AFUE with electronically commutated motor (ECM) $600
Natural gas furnace ≥ 95% AFUE with electronically commutated motor (ECM) $300
Integrated or combination water and space heating systems are another option. A condensing boiler condenses the water vapor produced in the combustion process and uses the heat from this condensation.
Product Rebate
Natural gas condensing boiler with on-demand water heating ≥ 95% AFUE $1,600
Natural gas condensing boiler with on-demand water heating ≥ 90% AFUE $1,200

High-efficiency natural gas water heaters
Upgrade to a high-efficiency natural gas water heater and save up to 30% on your water heating costs every year.
On-demand tankless water heaters save energy by heating water only when needed, eliminating energy lost during standby operation. Electronic ignition also helps save money and energy, as it eliminates the need for a pilot light.
The Energy Factor (EF) indicates a water heater’s overall energy efficiency based on the amount of hot water produced per unit of fuel consumed over a typical day. The higher the EF, the more efficient the water heater.
Product Rebate
On-demand tankless water heater ≥ .94 EF with electronic ignition $800
On-demand tankless water heater ≥ .82 EF with electronic ignition $500
Condensing water heaters work much like standard water heaters: a large, insulated tank of water is heated by a gas burner. But instead of venting the combustion gases directly outside, those gases are captured and utilized to further heat the water, increasing efficiency.
Product Rebate
Condensing gas water heater ≥ 95% Thermal Efficiency $500
Indirect water heaters use your boiler to heat a fluid that’s circulated through a heat exchanger in the storage tank. The energy stored by the water tank allows your heating system to turn on and off less often, which saves energy.
Product Rebate
Indirect water heater connected to a natural gas forced hot water boiler $400
ENERGY STAR® certified gas storage water heaters use the same technology as standard gas storage water heaters: a glass-lined steel tank is heated by a burner located at the bottom of the tank. High-efficiency models have better insulation, heat traps, and more efficient burners.
Product Rebate
ENERGY STAR® certified storage water heater ≥ .67 Energy Factor $100

Boiler reset controls
A boiler reset control senses outdoor temperatures and automatically turns down the boiler’s water temperature on milder days, from 180°F to about 120°F. This helps your boiler to operate at the right level, saving you 10% or more on heating costs every year.
Product Rebate
After market boiler reset control (add on unit attached to a natural gas forced hot water boiler) $225

Wi-Fi programmable thermostats
Use a Wi-Fi programmable thermostat to pre-set higher temperatures in the summer and lower temperatures in the winter when you’re typically away from home or asleep. You can set the temperature of your home remotely, using your mobile phone, tablet, or computer, and you’ll save up to $180 in heating and cooling costs every year.
Product Rebate
Wi-Fi programmable thermostat * $100
* Wi-Fi connections must be enabled. Rebate not to exceed purchase price. Limit two thermostats per account.
Use the table below as a starting point for setting energy-saving temperatures:
SettingTimeHeating TemperatureCooling Temperature
Wake6:00 a.m.< 70° F> 78° F
Day8:00 a.m.< 62° F> 85° F
Evening6:00 p.m.< 70° F> 78° F
Sleep10:00 p.m.< 62° F> 82° F

7-day programmable thermostats
Use a 7-day programmable thermostat to pre-set higher temperatures in the summer and lower temperatures in the winter when you’re typically away from home or asleep. 7-day models are useful if your schedule varies from day-to-day. For example, if children are home earlier on some days. These models give you the most flexibility, and let you set different programs for different days, usually with four possible temperature periods per day. You’ll save up to $180 in heating and cooling costs every year.

7-day programmable thermostat * $25
* Rebate not to exceed purchase price. Limit two thermostats per account.
