Dedham will receive $702,800 in federal weatherization recovery funds to replace old, inefficient heating systems in public housing units.
The upgrades, which mean lower energy costs for tenants in family developments, are to be made to about 100 two- and three-bedroom apartments on Parker Staples and Veterans roads.
The town is one of 19 communities chosen to share $25 million earmarked for conversion to energy-efficient heating systems. Other suburbs south of Boston that will also receive funds include Brockton, Mattapoisett, and Stoughton, at $394,629, $62,010, and $92,295, respectively.
Funds from the American Recovery and Reinvestment Act come to the Massachusetts Department of Housing and Community Development from the U.S. Department of Energy and are administered locally by a statewide network of local non-profit agencies.
Under program requirements, funds must be used for weatherization of housing where tenants pay for their own heat and earn under 60 percent of area median income. The balance of funds will provide eligible private households with full-scale home energy conservation services.
Federal officials have estimated that the entire $122 million available will be used to weatherize an estimated 16,900 homes over the next three years.
Improvements can range from air sealing and weather stripping to repairs or replacement of expired heating systems to attic, wall and floor insulation, and storm or replacement windows.
