Nashville / Oak Ridge
Oak Ridge has 32,693 residents (give or take 29) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4755120, checked 2026-10-19), about 383 people per square mile.
Oak Ridge is about 140 miles from the Census center point for Nashville in a straight line and covers 85.25 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 Oak Ridge that is 37830 (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 14,015 occupied homes in Oak Ridge, 52% heat with natural gas, 0% with heating oil, 46% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4755120, checked 2026-10-19).
Gas heats 52% of Oak Ridge against electricity at 46%, 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.
Oak Ridge has about the Anderson County oil share of 0% and 11 points less electric heat than the county's 57% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US47001, checked 2026-10-19).
Oak Ridge has 15,279 housing units, 1% built before 1940 and 67% before 1980, with 16% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4755120, checked 2026-10-19).
The median Oak Ridge home was built in 1965 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4755120, checked 2026-10-19) and the median home has 5.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4755120, checked 2026-10-19).
69% of Oak Ridge homes are single-family detached, 6% 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=160XX00US4755120, checked 2026-10-19).
34% of Oak Ridge homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4755120, checked 2026-10-19), so beside the 69% 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 Oak Ridge on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Heating design temperature: 20F.

That 20F figure is the Anderson County cold-day number a Oak Ridge heat pump is sized against, so ask the installer to show the system's heating output at 20F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 52% of Oak Ridge on gas and 46% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Oak Ridge home has 5.9 rooms and was built around 1965, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
