Cincinnati / Norwalk
Norwalk has 17,095 residents (give or take 26) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3957302, checked 2026-10-19), about 1,928 people per square mile.
Norwalk is about 177 miles from the Census center point for Cincinnati in a straight line and covers 8.865 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 7,434 occupied homes in Norwalk, 71% heat with natural gas, 0% with heating oil, 28% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3957302, checked 2026-10-19).
Gas heats 71% of Norwalk against electricity at 28%, so most quotes here are a partial-home system that carries the shoulder seasons and the summer while the gas boiler stays for the deepest cold, or a whole-home system when the house is ready for it.
Norwalk has about the Huron County oil share of 2% and 2 points more electric heat than the county's 26% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US39077, checked 2026-10-19).
Norwalk has 7,898 housing units, 21% built before 1940 and 64% before 1980, with 16% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3957302, checked 2026-10-19).
The median Norwalk home was built in 1968 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3957302, checked 2026-10-19) and the median home has 5.7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3957302, checked 2026-10-19).
61% of Norwalk homes are single-family detached, 15% are in two- to four-unit buildings and 11% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3957302, checked 2026-10-19).
35% of Norwalk homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3957302, checked 2026-10-19), so beside the 61% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
No electric utility is on file for Norwalk on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Heating design temperature: 1F.

That 1F figure is the Huron County cold-day number a Norwalk heat pump is sized against, so ask the installer to show the system's heating output at 1F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 71% of Norwalk on gas and 28% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Norwalk home has 5.7 rooms and was built around 1968, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
