Salt Lake City / Herriman
Herriman is about 20 miles from the Census center point for Salt Lake City in a straight line and covers 23.156 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).
Herriman has 59,346 residents (give or take 38) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4934970, checked 2026-10-19), about 2,563 people per square mile.
The quote form takes a ZIP code; for Herriman that is 84096 (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 17,559 occupied homes in Herriman, 85% heat with natural gas, 0% with heating oil, 13% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4934970, checked 2026-10-19).
Herriman has about the Salt Lake County oil share of 0% and 3 points less electric heat than the county's 16% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US49035, checked 2026-10-19).
Gas heats 85% of Herriman against electricity at 13%, 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.
The median Herriman home was built in 2013 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4934970, checked 2026-10-19) and the median home has 7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4934970, checked 2026-10-19).
Herriman has 17,965 housing units, 1% built before 1940 and 4% before 1980, with 91% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4934970, checked 2026-10-19).
Herriman has 6 points fewer pre-1940 homes than Salt Lake County as a whole (7%) and 59 points more homes built after 2000 than the county's 32% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US49035, checked 2026-10-19).
91% of Herriman housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4934970, 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.
64% of Herriman homes are single-family detached, 2% are in two- to four-unit buildings and 16% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4934970, checked 2026-10-19).
21% of Herriman homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4934970, checked 2026-10-19), so beside the 64% 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 Herriman 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 Herriman is $122,650 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4934970, 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: 11F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Salt Lake County row, 99% heating, PDF pages 125 to 127 of 141 (Revised 11/11/2020), https://www.energystar.gov/sites/default/files/Design%20Temperature%20Limit%20Reference%20Guide%20(2019%20Ed)%20-%20ENERGY%20STAR%20Single-Family%20New%20Homes_Rev11.pdf, fetched 2026-10-19, 99%.
That 11F figure is the Salt Lake County cold-day number a Herriman heat pump is sized against, so ask the installer to show the system's heating output at 11F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 85% of Herriman on gas and 13% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Herriman home has 7 rooms and was built around 2013, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
