How Wellesley homes are heated
The main heating fuel in Wellesley's 9,174 occupied homes, and the age of its housing.
- 70%heat with natural gas
- 15%heat with oil
- 13%heat with electricity
- 34%of homes were built before 1940
Most homes, 70 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.
Wellesley has a lot of older housing: 34 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.
Utilities and rebates in Wellesley
Electricity in Wellesley comes from the Wellesley Municipal Light Plant (WMLP), the town's own utility. Mass Save's electric rebates do not apply to light plant customers, and WMLP runs its own rebate program instead. Check the current offers on its rebate page before you buy.
Natural gas comes from National Grid, a Mass Save sponsor, so gas customers can look at the offers on masssave.com too.
