Boston / Wellfleet
Wellfleet has 4,404 residents (give or take 321) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2500174385, checked 2026-10-19), about 223 people per square mile.
Wellfleet is about 59 miles from the Census center point for Boston in a straight line and covers 19.784 square miles of land (Census 2024 Gazetteer internal points and land area, https://www2.census.gov/geo/docs/maps-data/data/gazetteer/2024_Gazetteer/, checked 2026-10-19).
The quote form takes a ZIP code; for Wellfleet that is 02663, 02667 (Census 2020 ZCTA to county subdivision relationship file, ZIP areas at least 20% inside the town, https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_cousub20_natl.txt, checked 2026-10-19).
Wellfleet is spread out at 223 people per square mile across 19.784 square miles of land, so a long refrigerant line run between the outdoor unit and the farthest indoor head is the sizing question an installer checks first.
Of the 2,069 occupied homes in Wellfleet, 5% heat with natural gas, 44% with heating oil, 13% with electricity and 31% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2500174385, checked 2026-10-19).
Heating oil is the largest single fuel in Wellfleet at 44%, ahead of propane at 31%, so the usual job here is an oil boiler or furnace coming out and a cold-climate heat pump going in, with the oil tank removed.
Wellfleet has 25 points more oil heat than Barnstable County as a whole, where 19% of homes burn oil, and the same 13% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US25001, checked 2026-10-19).
Wellfleet has 4,643 housing units, 14% built before 1940 and 60% before 1980, with 16% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2500174385, checked 2026-10-19).
Wellfleet has 3 points more pre-1940 homes than Barnstable County as a whole (11%) and 3 points more homes built after 2000 than the county's 13% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US25001, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Wellfleet home was built in 1975 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2500174385, checked 2026-10-19) and the median home has 5.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2500174385, checked 2026-10-19).
90% of Wellfleet homes are single-family detached, 4% are in two- to four-unit buildings and 0% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2500174385, checked 2026-10-19).
With 90% detached houses and 4% in small multi-family buildings, a Wellfleet quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 15% of Wellfleet homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2500174385, checked 2026-10-19), the landlord signs the quote in many of them.
Wellfleet has 8 points more detached houses than Barnstable County overall (82%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US25001, checked 2026-10-19).
Only 15% of Wellfleet homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2500174385, checked 2026-10-19), so nearly every quote here is the resident talking to the installer directly, and the rebate goes to the person living in the house.
Only 16% of Wellfleet homes are new enough to pass the whole-home rebate's weatherization check on age, and 14% date from before 1940, so most of the other 84% show it with a home energy assessment before the heat pump goes in.
Eversource Energy lists Wellfleet among the Massachusetts communities it serves for electricity (Eversource Energy communities we serve, https://www.eversource.com/residential/services/communities-we-serve, checked 2026-10-19).
For a Wellfleet address billed by Eversource Energy, the Mass Save whole-home heat pump rebate is $2,650 per ton up to $8,500, and the partial-home rebate is $1,125 per ton up to $8,500; for projects installed on or after January 1, 2027, the whole-home figure drops to $2,350 per ton capped at $7,500 (Mass Save air-source heat pump rebates, https://www.masssave.com/residential/rebates-offers-services/heating-and-cooling/heat-pumps/air-source-heat-pumps, checked 2026-10-19).
Median household income in Wellfleet is $117,938 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2500174385, checked 2026-10-19); Mass Save's enhanced heat pump incentives are income-based and decided household by household, so the town median only hints at how many neighbors qualify.
Heating design temperature: 10F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Barnstable County row, 99% heating, PDF page 56 of 141 (Revised 11/11/2020), https://www.energystar.gov/sites/default/files/Design%20Temperature%20Limit%20Reference%20Guide%20(2019%20Ed)%20-%20ENERGY%20STAR%20Single-Family%20New%20Homes_Rev11.pdf, fetched 2026-10-19, 99%.
That 10F figure is the Barnstable County cold-day number a Wellfleet heat pump is sized against, so ask the installer to show the system's heating output at 10F, not at the milder rating-label temperature.
Ask what happens to the oil tank, since 44% of the 2,069 occupied Wellfleet homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Wellfleet home has 5.6 rooms and was built around 1975, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
