What winter actually asks of a system in Gloucester
Gloucester drops below freezing on about 126 nights a year, and below 10°F on about 14 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.

Gloucester heats mostly with oil. The city's own Climate Action and Resilience Plan puts fuel oil ahead of natural gas as the largest source of residential building emissions, and buildings account for close to 60 percent of the city's total emissions. Pair that with a housing stock where about half of everything predates 1940 and the pattern is clear: cellar-set oil-fired boilers and hydronic distribution rather than ducted warm air, in buildings whose original venting long predates modern high-efficiency appliances. Natural gas is present in Gloucester, but it is the second fuel here, not the default assumption.

Gloucester's 2022 CARP states that the major energy sources for buildings in the city are fuel oil and natural gas, and that the majority of residential building emissions come from fuel oil, followed by natural gas and electricity. Fuel oil accounts for 23.2 percent of total building energy emissions in the residential category alone.
About half of Gloucester's housing stock sits in buildings built before 1940, another 26 percent before 1980, and only 8 percent has been built since 2000 (ACS 5-year estimates, 2019-2023).
Gloucester commissioned a 2025 Utility Networked Geothermal System Feasibility Study examining a utility thermal energy network. The study notes that bedrock beneath the proposed network footprint is Cape Ann Granite, with thermal conductivity of approximately 1.7 Btu/hr-ft-degF and thermal diffusivity of about 1.0 ft2/day.
