Louisville / Henderson
Henderson has 27,852 residents (give or take 28) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US2135866, checked 2026-10-19), about 1,648 people per square mile.
Henderson is about 108 miles from the Census center point for Louisville in a straight line and covers 16.902 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 12,341 occupied homes in Henderson, 47% heat with natural gas, 0% with heating oil, 51% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2135866, checked 2026-10-19).
Electricity already heats 51% of Henderson homes, ahead of gas at 47%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Henderson has about the Henderson County oil share of 0% and 1 points less electric heat than the county's 52% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US21101, checked 2026-10-19).
Henderson has 13,585 housing units, 10% built before 1940 and 60% before 1980, with 16% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2135866, checked 2026-10-19).
Henderson tracks Henderson County on housing age, with the county at 9% pre-1940 and 18% post-2000 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US21101, checked 2026-10-19).
The median Henderson home was built in 1974 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2135866, checked 2026-10-19) and the median home has 5.1 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US2135866, checked 2026-10-19).
59% of Henderson homes are single-family detached, 14% are in two- to four-unit buildings and 18% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US2135866, checked 2026-10-19).
46% of Henderson homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2135866, checked 2026-10-19), so beside the 59% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Henderson has 8 points fewer detached houses than Henderson County overall (67%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US21101, checked 2026-10-19).
46% of Henderson homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2135866, 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.
60% of Henderson homes were built before 1980 and only 16% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2135866, 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 Henderson 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 Henderson is $48,186 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US2135866, 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 Henderson County cold-day number a Henderson 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 for the heat-loss calculation room by room; the median Henderson home has 5.1 rooms and was built around 1974, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
