Manchester / Newmarket
Newmarket has 9,463 residents (give or take 18) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US3301552340, checked 2026-10-19), about 751 people per square mile.
Newmarket is about 26 miles from the Census center point for Manchester in a straight line and covers 12.593 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 Newmarket that is 03857 (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 Newmarket is $100,845 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3301552340, 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 Newmarket homes are single-family detached, 9% are in two- to four-unit buildings and 36% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US3301552340, checked 2026-10-19).
47% of Newmarket homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3301552340, 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.
Newmarket has 23 points fewer detached houses than Rockingham County overall (65%) and 20 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).
47% of Newmarket homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3301552340, checked 2026-10-19), so the market splits between resident-led jobs where the occupant picks the system and landlord-led jobs where they do not, and the rebate paperwork differs.
Of the 4,345 occupied homes in Newmarket, 8% heat with natural gas, 35% with heating oil, 24% with electricity and 27% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US3301552340, checked 2026-10-19).
Heating oil is the largest single fuel in Newmarket at 35%, ahead of propane at 27%, 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.
Newmarket has 7 points less oil heat than Rockingham County as a whole, where 42% of homes burn oil, and 12 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 lists Newmarket among the New Hampshire communities it serves for electricity (New Hampshire Department of Energy, utilities by city and town, https://www.energy.nh.gov/utilities-providers/utilities-city-town, checked 2026-10-19).
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 Newmarket address before counting it. With 24% of Newmarket homes already on electric heat and 70% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Newmarket has 4,500 housing units, 18% built before 1940 and 43% before 1980, with 19% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3301552340, checked 2026-10-19).
Newmarket has 6 points more pre-1940 homes than Rockingham County as a whole (12%) and 4 points fewer homes built after 2000 than the county's 23% (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 Newmarket home was built in 1983 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3301552340, checked 2026-10-19) and the median home has 4.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US3301552340, checked 2026-10-19).

That 0F figure is the Rockingham County cold-day number a Newmarket 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 what happens to the oil tank, since 35% of the 4,345 occupied Newmarket homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Newmarket home has 4.9 rooms and was built around 1983, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
