Water Heaters

Save energy and reduce greenhouse gas emissions with an efficient water heater.
Back to Water Heating & Pipe Insulation
Higher-efficiency water heating systems can lower heating expenses, decrease equipment maintenance time, and lower greenhouse gas emissions.

Get incentives on electric heat pump water heaters. Heat pump water heaters are a highly efficient way to heat water, using electricity to pull heat from the surrounding air and transfer it to water enclosed in the tank.

In alignment with the commonwealth's climate policy and goals, including a mandate passed into law by the 2021 Climate Act, rebates, incentives and financing for equipment powered by natural gas, oil and propane are discontinued. Eligible natural gas heating and water heating equipment must have been purchased, installed, and completed applications submitted by September 30, 2024, to receive a rebate.
