Columbus / Granville
Granville has 5,999 residents (give or take 22) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3931402, checked 2026-10-19), about 1,247 people per square mile.
Granville is about 26 miles from the Census center point for Columbus in a straight line and covers 4.809 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 1,859 occupied homes in Granville, 81% heat with natural gas, 0% with heating oil, 14% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3931402, checked 2026-10-19).
Gas heats 81% of Granville against electricity at 14%, so most quotes here are a partial-home system that carries the shoulder seasons and the summer while the gas furnace handles the coldest nights, or a whole-home system when the house is ready for it.
Granville has about the Licking County oil share of 1% and 8 points less electric heat than the county's 22% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US39089, checked 2026-10-19).
Granville has 2,005 housing units, 24% built before 1940 and 44% before 1980, with 23% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3931402, checked 2026-10-19).
Granville has 9 points more pre-1940 homes than Licking County as a whole (15%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US39089, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Granville home was built in 1987 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3931402, checked 2026-10-19) and the median home has 7.7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3931402, checked 2026-10-19).
78% of Granville homes are single-family detached, 8% are in two- to four-unit buildings and 12% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3931402, checked 2026-10-19).
With 78% detached houses and 8% in small multi-family buildings, a Granville quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 18% of Granville homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3931402, checked 2026-10-19), the landlord signs the quote in many of them.
No electric utility is on file for Granville 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 Granville is $124,408 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US3931402, 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: 5F.

That 5F figure is the Licking County cold-day number a Granville heat pump is sized against, so ask the installer to show the system's heating output at 5F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 81% of Granville on gas and 14% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Granville home has 7.7 rooms and was built around 1987, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
