Camden / Sea Isle City
Sea Isle City has 2,000 residents (give or take 231) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3466390, checked 2026-10-19), about 907 people per square mile.
Sea Isle City is about 58 miles from the Census center point for Camden in a straight line and covers 2.204 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 Sea Isle City that is 08243 (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 Sea Isle City is $108,359 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US3466390, 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.
15% of Sea Isle City homes are single-family detached, 13% are in two- to four-unit buildings and 15% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3466390, checked 2026-10-19).
7% of Sea Isle City homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3466390, checked 2026-10-19), so beside the 15% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Sea Isle City has 37 points fewer detached houses than Cape May County overall (52%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US34009, checked 2026-10-19).
Only 7% of Sea Isle City homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3466390, 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 1,117 occupied homes in Sea Isle City, 80% heat with natural gas, 0% with heating oil, 19% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3466390, checked 2026-10-19).
Gas heats 80% of Sea Isle City against electricity at 19%, 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.
Sea Isle City has 3 points less oil heat than Cape May County as a whole, where 3% of homes burn oil, and 1 points less electric heat than the county's 20% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US34009, checked 2026-10-19).
No electric utility is on file for Sea Isle City on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Sea Isle City has 6,719 housing units, 3% built before 1940 and 23% before 1980, with 40% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3466390, checked 2026-10-19).
Sea Isle City has 10 points fewer pre-1940 homes than Cape May County as a whole (13%) and 15 points more homes built after 2000 than the county's 25% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US34009, checked 2026-10-19).
The median Sea Isle City home was built in 1992 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3466390, checked 2026-10-19) and the median home has 6.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3466390, checked 2026-10-19).
40% of Sea Isle City housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3466390, 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: 11F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Cape May County row, 99% heating, PDF pages 81 to 82 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 Cape May County cold-day number a Sea Isle City 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 80% of Sea Isle City on gas and 19% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Sea Isle City home has 6.6 rooms and was built around 1992, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
