Manchester / Hanover
Hanover has 11,685 residents (give or take 44) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US3300933860, checked 2026-10-19), about 238 people per square mile.
Hanover is about 63 miles from the Census center point for Manchester in a straight line and covers 49.028 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 Hanover that is 03750, 03755 (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).
Hanover is spread out at 238 people per square mile across 49.028 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 3,378 occupied homes in Hanover, 9% heat with natural gas, 48% with heating oil, 11% with electricity and 28% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US3300933860, checked 2026-10-19).
Heating oil is the largest single fuel in Hanover at 48%, ahead of propane at 28%, 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.
Hanover has 5 points more oil heat than Grafton County as a whole, where 43% of homes burn oil, and the same 11% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US33009, checked 2026-10-19).
Hanover has 4,056 housing units, 25% built before 1940 and 54% before 1980, with 15% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3300933860, checked 2026-10-19).
Hanover has 5 points more pre-1940 homes than Grafton County as a whole (20%) and 6 points fewer homes built after 2000 than the county's 21% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US33009, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Hanover home was built in 1976 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3300933860, checked 2026-10-19) and the median home has 6.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US3300933860, checked 2026-10-19).
67% of Hanover homes are single-family detached, 4% are in two- to four-unit buildings and 22% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US3300933860, checked 2026-10-19).
26% of Hanover homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3300933860, checked 2026-10-19), so beside the 67% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Hanover has 6 points more detached houses than Grafton County overall (61%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US33009, checked 2026-10-19).
Eversource, Liberty Utilities and New Hampshire Electric Cooperative each list Hanover 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 Hanover address before counting it. With 11% of Hanover homes already on electric heat and 85% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Median household income in Hanover is $169,583 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3300933860, 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.
Heating design temperature: -18F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Grafton County row, 99% heating, PDF page 81 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 -18F figure is the Grafton County cold-day number a Hanover heat pump is sized against, so ask the installer to show the system's heating output at -18F, not at the milder rating-label temperature.
Ask what happens to the oil tank, since 48% of the 3,378 occupied Hanover homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Hanover home has 6.9 rooms and was built around 1976, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
