The quote form takes a ZIP code; for Wareham that is 02538, 02558, 02571, 02576 (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).
Of the 10,395 occupied homes in Wareham, 46% heat with natural gas, 31% with heating oil, 11% with electricity and 9% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2502372985, checked 2026-10-19).
Gas leads in Wareham at 46%, but 40% of homes still burn delivered oil or propane, and those 4,158 or so homes are where a heat pump pays back fastest.
Wareham has about the Plymouth County oil share of 32% and 1 points less electric heat than the county's 12% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US25023, checked 2026-10-19).
Wareham has 12,752 housing units, 24% built before 1940 and 72% before 1980, with 14% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2502372985, checked 2026-10-19).
Wareham has 3 points more pre-1940 homes than Plymouth County as a whole (21%) and 4 points fewer homes built after 2000 than the county's 18% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US25023, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Wareham home was built in 1958 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2502372985, checked 2026-10-19) and the median home has 5.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2502372985, checked 2026-10-19).
81% of Wareham homes are single-family detached, 7% are in two- to four-unit buildings and 4% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2502372985, checked 2026-10-19).
With 81% detached houses and 7% in small multi-family buildings, a Wareham quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 16% of Wareham homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2502372985, checked 2026-10-19), the landlord signs the quote in many of them.
Wareham has 11 points more detached houses than Plymouth County overall (70%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US25023, checked 2026-10-19).
Only 14% of Wareham homes are new enough to pass the whole-home rebate's weatherization check on age, and 24% date from before 1940, so most of the other 86% show it with a home energy assessment before the heat pump goes in.
Eversource Energy lists Wareham 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 Wareham 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 Wareham is $90,383 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2502372985, 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: 9F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Plymouth 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 9F figure is the Plymouth County cold-day number a Wareham heat pump is sized against, so ask the installer to show the system's heating output at 9F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 46% of Wareham on gas and 11% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Wareham home has 5.2 rooms and was built around 1958, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
