Wichita / Ottawa
Ottawa has 12,678 residents (give or take 37) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US2053550, checked 2026-10-19), about 1,228 people per square mile.
Ottawa is about 129 miles from the Census center point for Wichita in a straight line and covers 10.321 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 5,233 occupied homes in Ottawa, 69% heat with natural gas, 0% with heating oil, 28% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2053550, checked 2026-10-19).
Gas heats 69% of Ottawa 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.
Ottawa has about the Franklin County oil share of 0% and 3 points less electric heat than the county's 31% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US20059, checked 2026-10-19).
Ottawa has 5,583 housing units, 24% built before 1940 and 62% before 1980, with 14% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2053550, checked 2026-10-19).
The median Ottawa home was built in 1967 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2053550, checked 2026-10-19) and the median home has 5.8 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US2053550, checked 2026-10-19).
67% of Ottawa homes are single-family detached, 12% are in two- to four-unit buildings and 10% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US2053550, checked 2026-10-19).
40% of Ottawa homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2053550, checked 2026-10-19), so beside the 67% 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 Ottawa on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Heating design temperature: 7F.

That 7F figure is the Franklin County cold-day number a Ottawa heat pump is sized against, so ask the installer to show the system's heating output at 7F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 69% of Ottawa 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 Ottawa home has 5.8 rooms and was built around 1967, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
