The oldest housing on this site
The North Shore has the oldest homes of any area here. The median house in Salem was built in 1938, in Marblehead in 1944, and in Lynn and Gloucester in 1946. In Salem, Lynn and Gloucester about a third of the housing is in two- to four-family houses, where one basement holds several water heaters and a leak upstairs lands on a tenant. Heaters above someone else.
Three towns with their own electric company
Peabody, Danvers and Marblehead each have a municipal light company with its own rebate on a heat pump water heater: $500 in Peabody and Marblehead, $300 in Danvers. Lynnfield is split between two municipal light companies. Everywhere else, Mass Save's $750 rebate applies.
The number on this page rings a plumber based in Lynn.
