Camden / Berlin
Berlin is about 13 miles from the Census center point for Camden in a straight line and covers 3.594 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).
Berlin has 7,539 residents (give or take 20) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3405440, checked 2026-10-19), about 2,098 people per square mile.
The quote form takes a ZIP code; for Berlin that is 08009 (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).
Of the 2,793 occupied homes in Berlin, 83% heat with natural gas, 1% with heating oil, 16% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3405440, checked 2026-10-19).
Berlin has 3 points less oil heat than Camden County as a whole, where 4% of homes burn oil, and 2 points less electric heat than the county's 18% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US34007, checked 2026-10-19).
Gas heats 83% of Berlin against electricity at 16%, 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.
The median Berlin home was built in 1975 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3405440, checked 2026-10-19) and the median home has 6.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3405440, checked 2026-10-19).
Berlin has 2,973 housing units, 12% built before 1940 and 58% before 1980, with 29% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3405440, checked 2026-10-19).
Berlin has 5 points fewer pre-1940 homes than Camden County as a whole (17%) and 18 points more homes built after 2000 than the county's 11% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US34007, checked 2026-10-19).
64% of Berlin homes are single-family detached, 12% are in two- to four-unit buildings and 13% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3405440, checked 2026-10-19).
29% of Berlin homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3405440, checked 2026-10-19), so beside the 64% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Berlin has 9 points more detached houses than Camden County overall (55%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US34007, checked 2026-10-19).
No electric utility is on file for Berlin 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 Berlin is $102,855 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US3405440, 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: 10F.

That 10F figure is the Camden County cold-day number a Berlin heat pump is sized against, so ask the installer to show the system's heating output at 10F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 83% of Berlin on gas and 16% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Berlin home has 6.2 rooms and was built around 1975, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
