How Watertown homes are heated
The main heating fuel in Watertown's 16,371 occupied homes, and the age of its housing.
- 67%heat with natural gas
- 13%heat with oil
- 15%heat with electricity
- 44%of homes were built before 1940
Most homes, 67 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.
Watertown has a lot of older housing: 44 percent of its homes were built before 1940. Houses of that age often heat with a boiler and radiators and have no ductwork, so ductless mini splits are usually the simplest way to add cooling. See mini split installation.
