How Massachusetts Households Heat Their Homes

Natural gas is currently the dominant heating source for homes in Massachusetts, although clean heating technologies have advanced in the Commonwealth with air source heat pumps leading the way. Air-source heat pumps are a more efficient and cost-effective way to heat your home using electricity at a fraction of the cost of oil or propane. As a result, an increasing number of Massachusetts’ households are installing air-source heat pumps and incentives are available through the Commonwealth’s Mass Save® energy efficiency programs. Additional information on heating technologies can be found on the Massachusetts Household Heating Costs webpage.

The U.S. Census Bureau reports occupied housing units by heating fuel. The latest American Community Survey estimate for 2021 is summarized in Figure 1 and Table 1 below. The U.S. Census Bureau provides a definition of occupied housing units and explains the count of occupied housing units is the same as the count of households. For convenience, DOER uses the term households when referring to the ACS data.

In New England as a whole, a smaller share of households heat their home using natural gas. Heating oil remains the second most prominent heating fuel, closely behind natural gas. Lack of natural gas infrastructure in Maine, Vermont, and parts of New Hampshire means less access to gas supplies. Several New England states offer incentives for high efficiency electric heating technologies which is increasing conversion from oil-sourced heating to air-source heat pumps. Figure 2 and Table 2 summarize ACS data for New England, which includes Massachusetts, Connecticut, Maine, New Hampshire, Rhode Island, and Vermont.
