Liberty and Unitil natural gas customers can participate in the mail-in rebate or in the instant contractor rebate offering listed below.

Rebates are available for businesses that install energy-efficient water heating equipment including the following:

There are 2 different ways that your natural gas NHSaves utility can help you save with water heaters:

1. Instant discounts at participating distributors

To receive an incentive that reduces the initial equipment purchase cost of your high-efficiency water heater and maximizes your savings through the Liberty’s and Unitil’s C&I Water Heater Initiative:

1. Determine Your Water Heating Needs
   • Contact your contractor to determine the water heating needs for your business.
2. Find a Participating Distributor
   • Click here for a list of Participating Distributors and incentives or ask your contractor to reach out to a participating distributor who can work with you and your contractor to identify the right kind of high-efficiency equipment for your business.
3. Start Saving Energy
   • By purchasing a high-efficiency Water Heater, you may benefit from the energy savings over the lifetime of that equipment.

This simplified process is the easiest way to participate. Your purchase of a qualifying high-efficiency water heater is eligible for an incentive off the purchase price if:

• The water heater(s) will be installed for commercial or industrial use at a site that has a commercial or industrial natural gas account with one of the New Hampshire utilities; and
• You are not already receiving an incentive for the water heater equipment through another program sponsored by one of the NHSaves utility partners.

If you have questions about how to participate or enroll in Liberty’s and Unitil’s C&I Water Heater Initiative, please contact the initiative implementer:
Energy Solutions
617-440-5468
heat-ne@energy-solution.com

Incentives are provided directly to distributors by the utilities. Your contractor must provide the installation address and site information to the distributor to obtain the incentive. Contractors are expected to pass the incentive amount along to their customer.

2. Equipment rebates using your own contractor

If you have existing water heater and are looking to replace it, download and email or mail in the rebate form.

Qualifying Water Heater Equipment:

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.

Adding insulation and air sealing can save natural gas by reducing your building’s heating requirements. Please contact your utility or complete the custom rebate application for this offering.
Incentive Form

Surveys: Funded at 50% of the pre-approved survey cost. If all cost effective repairs/replacements are completed within 90 days of the survey, 100% of the survey cost may be reimbursed. (A 30-day customer commitment applies.)

Repairs: Once confirmed by inspection that repairs/replacements have been completed, reimbursements are available up to 50% of actual repair and/or replacement costs.

Custom Incentive Form

Please contact your utility or complete the Custom Rebate application for this offering.

Restaurant owners and operators are eligible for rebates when they improve the performance of their facilities and reduce energy costs. Incentives are available for:

Energy audits and financial incentives are available for energy-saving measures to multifamily facilities on qualifying commercial rates. These include:

• Space heating or water heating systems.
• Steam system upgrades.
• Building insulation and air sealing.
• Thermostats and water-saving devices.

No-cost energy assessments are available to natural gas customers to help identify opportunities for improved energy efficiency. Please see the “NATURAL GAS FLYER” for utility contact information. Contact your utility representative to request an energy assessment.

NATURAL GAS FLYER

Energy savings installations that use natural gas more efficiently than industry practices or building code requirements may qualify for custom incentives. Project costs and energy savings are quantified through a benefit/cost model to determine eligibility. (May include insulation and air sealing.)

Any business, regardless of size or industry, may inquire about custom incentives and technical support if there are no standard incentives available to fit their needs. These projects are unique and typically require additional energy analysis or other technical assistance.  Technical assistance & engineering services support for businesses implementing customized energy efficiency projects may be available—including quantifying how much energy is projected to be saved at project completion.

New Equipment & Construction: Up to 75% of incremental costs

Retrofits: Up to 50% of project costs

Pre-approval of rebates by your utility provider is required prior to the purchase and installation of the energy-efficient equipment.

Please be sure to review Terms and Conditions for your utility:

New-construction high-performance building projects encompass two categories:

• New buildings where equipment is being installed for the first time.
• Existing buildings where current equipment has reached the “end-of-life” period and must be replaced.

When it is necessary to quantify the energy savings potential of a proposed project, Liberty and Unitil will typically fund as much as 50% of the cost incurred as part of an engineering study (up to $10,000). The study to quantify the savings must be pre-approved and completed by an energy efficiency professional.
