Manchester / Bethlehem
Bethlehem has 2,537 residents (give or take 17) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US3300905460, checked 2026-10-19), about 28 people per square mile.
Bethlehem is about 89 miles from the Census center point for Manchester in a straight line and covers 90.6 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 Bethlehem that is 03574 (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).
Bethlehem is spread out at 28 people per square mile across 90.6 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 1,053 occupied homes in Bethlehem, 4% heat with natural gas, 57% with heating oil, 5% with electricity and 18% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US3300905460, checked 2026-10-19).
Heating oil is the largest single fuel in Bethlehem at 57%, ahead of propane at 18%, 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.
Bethlehem has 14 points more oil heat than Grafton County as a whole, where 43% of homes burn oil, and 6 points less electric heat than the county's 11% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US33009, checked 2026-10-19).
Bethlehem has 1,367 housing units, 29% built before 1940 and 57% before 1980, with 27% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3300905460, checked 2026-10-19).
Bethlehem has 9 points more pre-1940 homes than Grafton County as a whole (20%) and 6 points more 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 Bethlehem home was built in 1973 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3300905460, checked 2026-10-19) and the median home has 5.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US3300905460, checked 2026-10-19).
74% of Bethlehem homes are single-family detached, 11% are in two- to four-unit buildings and 6% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US3300905460, checked 2026-10-19).
With 74% detached houses and 11% in small multi-family buildings, a Bethlehem quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 25% of Bethlehem homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3300905460, checked 2026-10-19), the landlord signs the quote in many of them.
Bethlehem has 13 points more detached houses than Grafton County overall (61%) and 10 points fewer five-plus-unit buildings than the county's 16% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US33009, checked 2026-10-19).
Eversource lists Bethlehem 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 Bethlehem address before counting it. With 5% of Bethlehem homes already on electric heat and 79% 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 Bethlehem is $85,029 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3300905460, 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 Bethlehem 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 57% of the 1,053 occupied Bethlehem homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Bethlehem home has 5.9 rooms and was built around 1973, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
