Hartford / Naugatuck
Naugatuck has 31,800 residents (give or take 63) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US0914049950, checked 2026-10-19), about 1,941 people per square mile.
Naugatuck is about 27 miles from the Census center point for Hartford in a straight line and covers 16.384 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 Naugatuck that is 06770 (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 12,736 occupied homes in Naugatuck, 28% heat with natural gas, 44% with heating oil, 20% with electricity and 5% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US0914049950, checked 2026-10-19).
Heating oil is the largest single fuel in Naugatuck at 44%, ahead of gas at 28%, so the usual job here is an oil boiler or furnace coming out and a cold-climate heat pump going in, with the oil tank removed.
Naugatuck has about the Naugatuck Valley Planning Region oil share of 42% and 1 points less electric heat than the county's 21% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US09140, checked 2026-10-19).
Naugatuck has 13,245 housing units, 20% built before 1940 and 67% before 1980, with 9% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US0914049950, checked 2026-10-19).
Naugatuck tracks Naugatuck Valley Planning Region on housing age, with the county at 19% pre-1940 and 11% post-2000 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US09140, checked 2026-10-19).
The median Naugatuck home was built in 1971 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US0914049950, checked 2026-10-19) and the median home has 5.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US0914049950, checked 2026-10-19).
56% of Naugatuck homes are single-family detached, 16% are in two- to four-unit buildings and 17% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US0914049950, checked 2026-10-19).
32% of Naugatuck homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US0914049950, checked 2026-10-19), so beside the 56% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
67% of Naugatuck homes were built before 1980 and only 9% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US0914049950, checked 2026-10-19), so most of the stock predates modern insulation codes; the installer's heat-loss calculation, not a square-footage rule, decides the tonnage.
No electric utility is on file for Naugatuck on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Energize CT residential heat pump rebate, run by Energize CT, is a live program for Connecticut addresses and publishes its terms without one headline figure (registry row 3 verified 2026-10-15, https://www.energizect.com/node/68091, checked 2026-10-16); confirm eligibility for the Naugatuck address before counting it. With 20% of Naugatuck homes already on electric heat and 77% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Median household income in Naugatuck is $96,324 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US0914049950, 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.

That 2F figure is the New Haven County cold-day number a Naugatuck heat pump is sized against, so ask the installer to show the system's heating output at 2F, not at the milder rating-label temperature.
Ask what happens to the oil tank, since 44% of the 12,736 occupied Naugatuck homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Naugatuck home has 5.6 rooms and was built around 1971, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
