Wilmington / Long Neck
Long Neck has 2,161 residents (give or take 367) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1043245, checked 2026-10-19), about 783 people per square mile.
Long Neck is about 79 miles from the Census center point for Wilmington in a straight line and covers 2.759 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).
Median household income in Long Neck is $56,745 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1043245, 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.
22% of Long Neck homes are single-family detached, 1% are in two- to four-unit buildings and 3% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1043245, checked 2026-10-19).
8% of Long Neck homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1043245, checked 2026-10-19), so beside the 22% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Long Neck has 43 points fewer detached houses than Sussex County overall (65%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US10005, checked 2026-10-19).
Only 8% of Long Neck homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1043245, 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.
Of the 1,235 occupied homes in Long Neck, 3% heat with natural gas, 4% with heating oil, 27% with electricity and 64% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1043245, checked 2026-10-19).
Propane leads in Long Neck at 64%, ahead of electricity at 27%, and a propane home is the clearest heat pump case on this door because delivered fuel is priced per gallon with no pipe to fall back on.
Long Neck has 3 points less oil heat than Sussex County as a whole, where 7% of homes burn oil, and 26 points less electric heat than the county's 53% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US10005, checked 2026-10-19).
No electric utility is on file for Long Neck on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Long Neck has 2,298 housing units, 1% built before 1940 and 14% before 1980, with 57% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1043245, checked 2026-10-19).
Long Neck has 3 points fewer pre-1940 homes than Sussex County as a whole (4%) and 8 points more homes built after 2000 than the county's 49% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US10005, checked 2026-10-19).
The median Long Neck home was built in 2001 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1043245, checked 2026-10-19) and the median home has 5.5 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1043245, checked 2026-10-19).
57% of Long Neck housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1043245, checked 2026-10-19), and homes that recent usually meet the insulation codes in place at the time, so a heat pump sized to the floor plan lands closer to the real load than it would in an older neighborhood.
Heating design temperature: 18F.

That 18F figure is the Sussex County cold-day number a Long Neck 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 for the heat-loss calculation room by room; the median Long Neck home has 5.5 rooms and was built around 2001, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
