Wilmington / Clayton
Clayton has 4,222 residents (give or take 24) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1015440, checked 2026-10-19), about 2,167 people per square mile.
Clayton is about 32 miles from the Census center point for Wilmington in a straight line and covers 1.948 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).
Of the 1,195 occupied homes in Clayton, 89% heat with natural gas, 0% with heating oil, 6% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1015440, checked 2026-10-19).
Gas heats 89% of Clayton against electricity at 6%, so most quotes here are a partial-home system that carries the shoulder seasons and the summer while the gas furnace handles the coldest nights, or a whole-home system when the house is ready for it.
Clayton has 10 points less oil heat than Kent County as a whole, where 10% of homes burn oil, and 28 points less electric heat than the county's 34% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US10001, checked 2026-10-19).
Clayton has 1,195 housing units, 16% built before 1940 and 20% before 1980, with 73% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1015440, checked 2026-10-19).
Clayton has 9 points more pre-1940 homes than Kent County as a whole (7%) and 33 points more homes built after 2000 than the county's 40% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US10001, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Clayton home was built in 2005 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1015440, checked 2026-10-19) and the median home has 7.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1015440, checked 2026-10-19).
88% of Clayton homes are single-family detached, 2% are in two- to four-unit buildings and 0% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1015440, checked 2026-10-19).
With 88% detached houses and 2% in small multi-family buildings, a Clayton quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 10% of Clayton homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1015440, checked 2026-10-19), the landlord signs the quote in many of them.
Clayton has 23 points more detached houses than Kent County overall (65%) and 11 points fewer five-plus-unit buildings than the county's 11% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US10001, checked 2026-10-19).
Only 10% of Clayton homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1015440, 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.
73% of Clayton housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1015440, 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.
No electric utility is on file for Clayton on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Median household income in Clayton is $107,307 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1015440, 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: 11F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Kent County row, 99% heating, PDF page 17 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 11F figure is the Kent County cold-day number a Clayton heat pump is sized against, so ask the installer to show the system's heating output at 11F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 89% of Clayton on gas and 6% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Clayton home has 7.2 rooms and was built around 2005, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
