What winter actually asks of a system in Wilmington
Wilmington drops below freezing on about 134 nights a year, and below 10°F on about 17 of them. Those coldest nights — not the average winter day — are what a furnace, boiler or heat pump has to be sized for. A system that keeps up in November and struggles in January is usually a sizing problem, not a broken one.

Wilmington systems & permits
Wilmington sits inland in the Shawsheen basin, whose 1971-2000 baseline is 6,457 heating degree-days — roughly 380 more than the coastal Boston Harbor basin that covers Winchester and Winthrop. Natural gas is distributed by National Grid, which has run main replacement and new-main installation on town streets. The unusual part is the incentive picture: Wilmington's electricity comes from Reading Municipal Light Department, a municipal utility that runs its own rebate programs, so the Mass Save electric-side numbers quoted in most Massachusetts towns do not apply here.

The Shawsheen basin's 1971-2000 observed baseline is 6,457 annual heating degree-days (3,341 in winter), against 6,079 for the coastal Boston Harbor basin. Wilmington is listed within the Shawsheen basin.
RMLD states that as a municipal electric utility it "operates its own energy efficiency and rebate programs that are separate from privately owned electric utility programs offered by Mass Save," that RMLD customers "are solely eligible for electricity-related rebates offered by RMLD," and that RMLD customers served by a Mass Save participating natural gas provider may still be eligible for natural-gas-specific Mass Save rebates.
RMLD's residential rebate menu includes a Heat Pump Rebate or 0% Interest Loan for RMLD residential customers installing heat pumps at their primary home in RMLD territory. RMLD states rebate processing takes 60-180 days.
Under National Grid's Natural Gas Main Replacement program, "Meters will need to be relocated to the outside of the home or business if currently inside," and old gas pipes and service lines are replaced with plastic and/or coated steel.
