Newer houses
The median home in Ashland was built in 1984, which makes it one of the newest towns on this site. Seven in ten homes are single-family and 65 percent heat with gas.
A house from the 1980s is likely on its third or fourth water heater. The serial number tells you how old the current one is.
Blended water
Ashland takes part of its water from the MWRA and treats the rest at its own plant on Howe Street. The town also sells water to Hopkinton. The blend is not the same as straight MWRA water, so ask the water department for the hardness figure. What it means for a tank.
Gas and rebates
Eversource is the gas company. For a gas smell, leave and call 911, then Eversource at 800-592-2000. Eversource also supplies the electricity, so Mass Save's 2026 rebate of $750 on a heat pump water heater applies.
