How Marlborough homes are heated
The main heating fuel in Marlborough's 16,665 occupied homes, and the age of its housing.
- 61%heat with natural gas
- 11%heat with oil
- 22%heat with electricity
- 21%of homes were built before 1940
Most homes, 61 percent, heat with natural gas, through a furnace or a boiler. A tune-up every fall keeps either one running safely. See furnace maintenance and boiler maintenance.
About one home in five here was built before 1940. Older houses often heat with radiators and have no ducts for central air, which is where ductless mini splits come in.
22 percent of homes heat with electricity, either with a heat pump or with electric baseboard. Baseboard heat is simple but costly to run, and a heat pump makes the same heat with much less electricity.
