Manchester / New London
New London has 4,433 residents (give or take 19) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US3301352100, checked 2026-10-19), about 198 people per square mile.
New London is about 41 miles from the Census center point for Manchester in a straight line and covers 22.34 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 New London that is 03233, 03257 (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).
New London is spread out at 198 people per square mile across 22.34 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 1,669 occupied homes in New London, 3% heat with natural gas, 45% with heating oil, 4% with electricity and 43% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US3301352100, checked 2026-10-19).
Heating oil is the largest single fuel in New London at 45%, ahead of propane at 43%, 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.
New London has 12 points more oil heat than Merrimack County as a whole, where 33% of homes burn oil, and 9 points less electric heat than the county's 13% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US33013, checked 2026-10-19).
New London has 2,417 housing units, 22% 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=060XX00US3301352100, checked 2026-10-19).
New London has 5 points fewer homes built after 2000 than the county's 20% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US33013, checked 2026-10-19).
The median New London home was built in 1977 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3301352100, checked 2026-10-19) and the median home has 6.7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US3301352100, checked 2026-10-19).
81% of New London homes are single-family detached, 3% are in two- to four-unit buildings and 10% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US3301352100, checked 2026-10-19).
With 81% detached houses and 3% in small multi-family buildings, a New London quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 9% of New London homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3301352100, checked 2026-10-19), the landlord signs the quote in many of them.
New London has 18 points more detached houses than Merrimack County overall (63%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US33013, checked 2026-10-19).
Only 9% of New London homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3301352100, checked 2026-10-19), so nearly every quote here is the resident talking to the installer directly, and the rebate goes to the person living in the house.
Eversource lists New London 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 New London address before counting it. With 4% of New London homes already on electric heat and 91% 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 New London is $107,773 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3301352100, 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: -4F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Merrimack 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 -4F figure is the Merrimack County cold-day number a New London heat pump is sized against, so ask the installer to show the system's heating output at -4F, not at the milder rating-label temperature.
Ask what happens to the oil tank, since 45% of the 1,669 occupied New London homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median New London home has 6.7 rooms and was built around 1977, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
