Instant Water Heater Incentives

Discounted pricing on energy-efficient water heating equipment for commercial installers.

Save Money and Energy with an Efficient Water Heater

To ensure customers receive the benefits of high-efficiency, the Sponsors of Mass Save® are offering instant incentives on commercial water heating equipment. This initiative is a market transformation initiative that partners with distributors to offer monetary incentives on high-efficiency water heaters to commercially metered customers.

Water heating accounts for approximately 20% of natural gas use in commercial applications. Installing a high-efficiency water heater can result in energy bill savings, provide better comfort and control, and can lower water and sewage costs.


How to Receive Instant Incentives on High-Efficiency Water Heaters


  • 1 Determine Your Water Heating Needs

    Contact your local water heating contractor to determine the heating and cooling needs of your business 

  • 2 Find a Participating Distributor

    Please use the tool below to locate participating distributors who can work with you and your contractor to identify the right kind of high-efficiency equipment for your business. Your contractor must provide the installation address and site information to the distributor to obtain the incentive. 

  • 3 Start Saving Energy

    By purchasing high-efficiency water heating equipment you may benefit from the energy savings over the lifetime of that equipment.

There are several high-efficiency water heating options available to commercial customers. Download the C&I water heater qualifying equipment table and discuss the best options for your business with your contractor.

Condensing storage water heaters utilize the heat from exhaust gas to heat water efficiently. Condensing storage water heaters can support multiple, simultaneous uses of hot water and are preferred for emergency replacement situations because of the ease of installation. Field-supplied materials are limited to piping and fittings near the heater because these water heaters use the same gas line as the unit they are replacing.

On-demand tankless water heaters provide a constant supply of hot water and are not subject to standby energy loss since they heat water only when needed. Tankless water heaters are well-suited for facilities with restricted or limited space because they do not require a storage tank.

Indirect water heaters consist of a storage tank that connects to a building's main furnace or boiler to heat water. The energy stored by the tank allows the furnace or boiler to turn off and on less often, saving energy. Because they can be installed without additional exhaust piping, indirect water heaters tend to have lower installation and maintenance costs than traditional water heaters.

Condensing volume water heaters utilize heat from exhaust gas to heat water efficiently. Because they produce a high output, condensing hot water boilers can be a good option for facilities with high-volume hot water demands.

Electric heat pump water heaters utilize electricity to move heat from one place to another instead of generating heat directly. Therefore, they can be two to three times more energy efficient than conventional electric resistance water heaters.



The water heater(s) will be installed for commercial or industrial use at a site that has a commercial or industrial gas or electric account with one of the Sponsors: Berkshire Gas, Cape Light Compact, Eversource, Liberty Utilities, National Grid, or Unitil; and you are not already receiving an incentive for the water heater equipment through another program through Mass Save or one of its Sponsors.

Incentives are provided directly to distributors by the Sponsors. Contractors are expected to pass the incentive amount along to their customer. For questions on the incentive amount or to confirm that the incentive was included in your purchase, please reach out to your contractor.
