Wilmington / Newark
Newark has 30,330 residents (give or take 122) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1050670, checked 2026-10-19), about 3,201 people per square mile.
Newark is about 13 miles from the Census center point for Wilmington in a straight line and covers 9.474 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 Newark that is 19711, 19716, 19717 (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).
Median household income in Newark is $76,912 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1050670, 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.
3,201 people per square mile puts Newark in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
43% of Newark homes are single-family detached, 5% are in two- to four-unit buildings and 36% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1050670, checked 2026-10-19).
49% of Newark homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1050670, checked 2026-10-19), so beside the 43% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Newark has 10 points fewer detached houses than New Castle County overall (53%) and 17 points more five-plus-unit buildings than the county's 19% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US10003, checked 2026-10-19).
49% of Newark homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1050670, checked 2026-10-19), so the market splits between resident-led jobs where the occupant picks the system and landlord-led jobs where they do not, and the rebate paperwork differs.
Of the 8,594 occupied homes in Newark, 56% heat with natural gas, 8% with heating oil, 35% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1050670, checked 2026-10-19).
Gas heats 56% of Newark against electricity at 35%, 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.
Newark has about the New Castle County oil share of 9% and 3 points more electric heat than the county's 32% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US10003, checked 2026-10-19).
No electric utility is on file for Newark on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Newark has 9,921 housing units, 5% built before 1940 and 54% before 1980, with 19% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1050670, checked 2026-10-19).
Newark has 6 points fewer pre-1940 homes than New Castle County as a whole (11%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US10003, checked 2026-10-19).
The median Newark home was built in 1978 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1050670, 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=160XX00US1050670, checked 2026-10-19).
Heating design temperature: 11F.

That 11F figure is the New Castle County cold-day number a Newark 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 56% of Newark on gas and 35% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Newark home has 5.9 rooms and was built around 1978, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
