Manchester / Exeter
Exeter has 16,151 residents (give or take 35) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US3301525380, checked 2026-10-19), about 824 people per square mile.
Exeter is about 24 miles from the Census center point for Manchester in a straight line and covers 19.603 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 Exeter that is 03833 (Census 2020 ZCTA to county subdivision and ZCTA to place relationship files, ZIP areas at least 20% inside the town, https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_cousub20_natl.txt and https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_place20_natl.txt, checked 2026-10-19).
Median household income in Exeter is $110,346 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3301525380, checked 2026-10-19); many state and utility heat pump rebate programs set higher incentive tiers for income-qualifying households, so the household income on the application, not the town median, decides which level applies.
42% of Exeter homes are single-family detached, 14% are in two- to four-unit buildings and 26% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US3301525380, checked 2026-10-19).
31% of Exeter homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3301525380, checked 2026-10-19), so beside the 42% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Exeter has 23 points fewer detached houses than Rockingham County overall (65%) and 10 points more five-plus-unit buildings than the county's 16% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US33015, checked 2026-10-19).
Of the 6,900 occupied homes in Exeter, 35% heat with natural gas, 25% with heating oil, 17% with electricity and 18% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US3301525380, checked 2026-10-19).
Gas leads in Exeter at 35%, but 43% of homes still burn delivered oil or propane, and those 2,967 or so homes are where a heat pump pays back fastest.
Exeter has 17 points less oil heat than Rockingham County as a whole, where 42% of homes burn oil, and 5 points more electric heat than the county's 12% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US33015, checked 2026-10-19).
Eversource and Unitil each list Exeter for electric service (New Hampshire Department of Energy, utilities by city and town, https://www.energy.nh.gov/utilities-providers/utilities-city-town, checked 2026-10-19); the bill decides the rebate path.
NHSaves air source heat pump rebate, run by NHSaves (Eversource, Liberty, Unitil), is a live program for New Hampshire addresses and lists a standard figure of $250 (registry row 6 verified 2026-10-14, https://nhsaves.com/residential/electric-heating-cooling-equipment/, checked 2026-10-16); confirm eligibility for the Exeter address before counting it. With 17% of Exeter homes already on electric heat and 78% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Exeter has 7,342 housing units, 23% built before 1940 and 51% before 1980, with 23% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3301525380, checked 2026-10-19).
Exeter has 11 points more pre-1940 homes than Rockingham County as a whole (12%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US33015, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Exeter home was built in 1979 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3301525380, 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=060XX00US3301525380, checked 2026-10-19).

That 0F figure is the Rockingham County cold-day number a Exeter heat pump is sized against, so ask the installer to show the system's heating output at 0F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 35% of Exeter on gas and 17% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Exeter home has 5.2 rooms and was built around 1979, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
