Seattle / Ellensburg
Ellensburg has 20,874 residents (give or take 52) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US5321240, checked 2026-10-19), about 2,406 people per square mile.
Ellensburg is about 95 miles from the Census center point for Seattle in a straight line and covers 8.677 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).
Median household income in Ellensburg is $55,438 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5321240, 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.
44% of Ellensburg homes are single-family detached, 16% are in two- to four-unit buildings and 32% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US5321240, checked 2026-10-19).
67% of Ellensburg homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5321240, checked 2026-10-19), so beside the 44% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Ellensburg has 26 points fewer detached houses than Kittitas County overall (70%) and 18 points more five-plus-unit buildings than the county's 14% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US53037, checked 2026-10-19).
With 67% of Ellensburg homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5321240, checked 2026-10-19), most heat pump quotes here are landlord-driven: the landlord signs the contract and picks the equipment, and the tenant sees the lower bill.
Of the 8,972 occupied homes in Ellensburg, 23% heat with natural gas, 0% with heating oil, 74% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US5321240, checked 2026-10-19).
Electricity already heats 74% of Ellensburg homes, ahead of gas at 23%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Ellensburg has about the Kittitas County oil share of 2% and 14 points more electric heat than the county's 60% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US53037, checked 2026-10-19).

That 6F figure is the Kittitas County cold-day number a Ellensburg heat pump is sized against, so ask the installer to show the system's heating output at 6F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Ellensburg home has 4.5 rooms and was built around 1991, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
