Salt Lake City / Grantsville
Grantsville has 14,341 residents (give or take 37) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4931120, checked 2026-10-19), about 360 people per square mile.
Grantsville is about 30 miles from the Census center point for Salt Lake City in a straight line and covers 39.881 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).
Grantsville is spread out at 360 people per square mile across 39.881 square miles of land, so a long refrigerant line run between the outdoor unit and the farthest indoor head is the sizing question an installer checks first.
Of the 3,926 occupied homes in Grantsville, 73% heat with natural gas, 0% with heating oil, 24% with electricity and 3% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4931120, checked 2026-10-19).
Gas heats 73% of Grantsville against electricity at 24%, 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.
Grantsville has about the Tooele County oil share of 0% and 6 points more electric heat than the county's 18% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US49045, checked 2026-10-19).
Grantsville has 4,120 housing units, 7% built before 1940 and 25% before 1980, with 48% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4931120, checked 2026-10-19).
Grantsville tracks Tooele County on housing age, with the county at 5% pre-1940 and 46% post-2000 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US49045, checked 2026-10-19).
The median Grantsville home was built in 1999 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4931120, checked 2026-10-19) and the median home has 6.7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4931120, checked 2026-10-19).
84% of Grantsville homes are single-family detached, 3% are in two- to four-unit buildings and 7% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4931120, checked 2026-10-19).
With 84% detached houses and 3% in small multi-family buildings, a Grantsville quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 15% of Grantsville homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4931120, checked 2026-10-19), the landlord signs the quote in many of them.
Only 15% of Grantsville homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4931120, checked 2026-10-19), so nearly every quote here is the resident talking to the installer directly, and the rebate goes to the person living in the house.
48% of Grantsville housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4931120, checked 2026-10-19), and homes that recent usually meet the insulation codes in place at the time, so a heat pump sized to the floor plan lands closer to the real load than it would in an older neighborhood.
No electric utility is on file for Grantsville 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 Grantsville is $101,349 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4931120, 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 Tooele County cold-day number a Grantsville 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 whether the quote is whole-home or partial-home, because with 73% of Grantsville on gas and 24% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Grantsville home has 6.7 rooms and was built around 1999, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
