Manchester / Walpole
Walpole has 3,690 residents (give or take 18) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US3300578420, checked 2026-10-19), about 105 people per square mile.
Walpole is about 49 miles from the Census center point for Manchester in a straight line and covers 35.226 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 Walpole that is 03604, 03608, 03609 (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).
Walpole is spread out at 105 people per square mile across 35.226 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 1,513 occupied homes in Walpole, 2% heat with natural gas, 69% with heating oil, 17% with electricity and 6% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US3300578420, checked 2026-10-19).
Heating oil is the largest single fuel in Walpole at 69%, ahead of electricity at 17%, 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.
Walpole has 12 points more oil heat than Cheshire County as a whole, where 57% of homes burn oil, and 7 points more electric heat than the county's 10% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US33005, checked 2026-10-19).
Walpole has 1,747 housing units, 33% built before 1940 and 62% before 1980, with 17% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3300578420, checked 2026-10-19).
Walpole has 6 points more pre-1940 homes than Cheshire County as a whole (27%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US33005, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Walpole home was built in 1967 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3300578420, checked 2026-10-19) and the median home has 5.8 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US3300578420, checked 2026-10-19).
78% of Walpole homes are single-family detached, 10% are in two- to four-unit buildings and 9% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US3300578420, checked 2026-10-19).
With 78% detached houses and 10% in small multi-family buildings, a Walpole quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 30% of Walpole homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3300578420, checked 2026-10-19), the landlord signs the quote in many of them.
Walpole has 9 points more detached houses than Cheshire County overall (69%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US33005, checked 2026-10-19).
33% of Walpole homes were built before 1940 and 62% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3300578420, checked 2026-10-19), so insulation is the first sizing question: an older home leaks more heat per square foot, and the installer runs a room-by-room heat-loss calculation to size the system for what the walls and windows actually hold in, not just the floor plan.
No electric utility is on file for Walpole on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
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 Walpole address before counting it. With 17% of Walpole homes already on electric heat and 77% 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 Walpole is $82,617 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3300578420, 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), Cheshire 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 Cheshire County cold-day number a Walpole 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 69% of the 1,513 occupied Walpole homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; a Walpole house from before 1940 (33% of the 1,747 units) rarely matches a square-footage rule of thumb.
