Seattle / Washougal
Washougal has 17,490 residents (give or take 41) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US5376405, checked 2026-10-19), about 2,939 people per square mile.
Washougal is about 141 miles from the Census center point for Seattle in a straight line and covers 5.952 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 6,200 occupied homes in Washougal, 45% heat with natural gas, 0% with heating oil, 50% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US5376405, checked 2026-10-19).
Electricity already heats 50% of Washougal homes, ahead of gas at 45%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Washougal has about the Clark County oil share of 0% and 12 points less electric heat than the county's 62% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US53011, checked 2026-10-19).
Washougal has 6,342 housing units, 8% built before 1940 and 33% before 1980, with 48% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5376405, checked 2026-10-19).
Washougal has 4 points more pre-1940 homes than Clark County as a whole (4%) and 13 points more homes built after 2000 than the county's 35% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US53011, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Washougal home was built in 1999 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US5376405, checked 2026-10-19) and the median home has 6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US5376405, checked 2026-10-19).
70% of Washougal homes are single-family detached, 10% are in two- to four-unit buildings and 8% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US5376405, checked 2026-10-19).
With 70% detached houses and 10% in small multi-family buildings, a Washougal quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 29% of Washougal homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5376405, checked 2026-10-19), the landlord signs the quote in many of them.
Washougal has 10 points fewer five-plus-unit buildings than the county's 18% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US53011, checked 2026-10-19).
48% of Washougal housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5376405, 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 Washougal on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
PSE heat pump rebates (electric resistance to ASHP conversion), run by Puget Sound Energy, is a live program for Washington addresses and covers qualifying equipment at $2,400 per system (registry row 14 verified 2026-10-14, https://www.pse.com/en/rebates/heating/electric-resistance-to-air-source-heat-pump-conversion-rebate, checked 2026-10-16); confirm eligibility for the Washougal address before counting it. With 50% of Washougal homes already on electric heat and 46% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Seattle City Light heat pump instant discounts, run by Seattle City Light, is a live program for Washington addresses and lists a standard figure of $300 (registry row 47 verified 2026-10-16, https://seattle.gov/city-light/residential-services/home-energy-solutions/heating-and-cooling-your-home, checked 2026-10-16); confirm eligibility for the Washougal address before counting it.
Seattle Clean Heat Program (oil to heat pump), run by City of Seattle Office of Sustainability and Environment, is a live program for Washington addresses and lists a standard figure of $2,000 (registry row 48 verified 2026-10-14, https://seattle.gov/environment/climate-change/buildings-and-energy/seattles-clean-heat-program, checked 2026-10-16); confirm eligibility for the Washougal address before counting it.
Median household income in Washougal is $106,368 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5376405, 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: 24F.

That 24F figure is the Clark County cold-day number a Washougal heat pump is sized against, so ask the installer to show the system's heating output at 24F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Washougal home has 6 rooms and was built around 1999, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
