The cheaper, cleaner alternative for heating and cooling your home is here!

HeatSmart Nantucket was a local program that offered smarter, cleaner alternatives to help Nantucket residents and businesses save on their energy bills. With support from a group of local volunteers and the Massachusetts Clean Energy Center, the Town of Nantucket provided Nantucket home and business owners with a simple way to learn about and purchase high-efficiency, year-round solar hot water systems and cold-climate air source heat pumps.

HeatSmart Nantucket closed to new sign-ups on June 30, 2019. If you are interested in learning more about how clean heating and cooling alternatives could save you money and improve the comfort of your home, read through our educational resources on the website or reach out to the Town's Energy Coordinator, Lauren Sinatra, at or 508-325-5379.

What is solar hot water? What is a heat pump?

HeatSmart Nantucket is offering two clean heating and cooling technologies supported by numerous state programs.

A turnkey solar hot water system uses renewable solar energy to heat your home or business' hot water. A year round solar hot water system is highly efficient with very little maintenance and will save you up to 80% on your hot water bills.

Heat pumps transfer heat in and out of buildings to provide heating and cooling in one system. They're not unlike air conditioners that can run in reverse and collect heat from the outdoor air—even when it's below -10°F outside. These cold climate-optimized, high-efficiency heat pumps can help you can save on your energy bill and improve the comfort of your home or business, all while reducing your greenhouse gas emissions!
