There are three ways to receive an instant rebate on qualifying heat pump water heaters.

1. Work with a Licensed Plumber/Installer
   Your plumber or installer can purchase a qualifying heat pump water heater at a Participating Distributor to receive an instant rebate of $750.
   
   Or
   
   
2. Purchase a System From a Participating Retailer
   The Sponsors of Mass Save have partnered with Home Depot and Lowes to offer residents instant, in-store discounts on qualifying heat pump water heaters. To receive the discount, visit MassSave.com/Instant to validate your eligibility and receive a code.
   
   You will need to have your utility account number on hand. Present the code at the register and an instant rebate of $750 will be applied to the purchase price.
   
   Or
   
   
3. Purchase a System from the Mass Save Heat Pump Water Heater Online Marketplace
   The Mass Save Heat Pump Water Heater Online Marketplace provides resources and guidance to help you decide if a heat pump water heater is right for your home. Through our Product Advisor tool, you can provide specific information about your home and potentially be eligible for a fixed-cost installation. The Mass Save Water Heater Savings Calculator can help you see how much you can save annually with a heat pump water heater. You have the option to purchase eligible water heaters for pick-up or delivery and/or get connected with a contractor for full installation. No matter which option you select, the $750 instant rebate will be applied directly to your purchase price.
   
   You will need to have your utility account number on hand and know what fuel you currently use to heat the water in your home.

If your equipment was purchased online or from a non-participating retailer or distributor without a rebate applied at the time of purchase, you can submit your rebate online via the Rebate Portal or download a mail-in rebate form. For questions about applied rebates, please contact your installation contractor.
