Madison / Whitewater
Whitewater has 15,807 residents (give or take 34) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US5586925, checked 2026-10-19), about 1,788 people per square mile.
Whitewater is about 39 miles from the Census center point for Madison in a straight line and covers 8.842 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 Whitewater is $54,969 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5586925, 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.
33% of Whitewater homes are single-family detached, 13% are in two- to four-unit buildings and 44% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US5586925, checked 2026-10-19).
With 44% of Whitewater homes in buildings of five or more units and 33% detached, the condo association usually decides where outdoor units can go, so that approval comes before the quote. With 68% of Whitewater homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5586925, checked 2026-10-19), the landlord signs the quote in many of them.
Whitewater has 37 points fewer detached houses than Walworth County overall (70%) and 28 points more five-plus-unit buildings than the county's 16% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US55127, checked 2026-10-19).
With 68% of Whitewater homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5586925, 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 5,229 occupied homes in Whitewater, 67% heat with natural gas, 0% with heating oil, 31% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US5586925, checked 2026-10-19).
Gas heats 67% of Whitewater against electricity at 31%, 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.
Whitewater has about the Walworth County oil share of 1% and 16 points more electric heat than the county's 15% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US55127, checked 2026-10-19).
No electric utility is on file for Whitewater on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Focus on Energy air source heat pump instant discount (ratepayer), run by Focus on Energy, is a live program for Wisconsin addresses and covers qualifying equipment at $900 per system (registry row 20 verified 2026-10-07, https://assets.focusonenergy.com/production/docs/trade-ally/TAS-Trade-Ally-Solutions-Rebates-Overview-20260101_CLEAN.pdf, checked 2026-10-16); confirm eligibility for the Whitewater address before counting it. With 31% of Whitewater homes already on electric heat and 68% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Whitewater has 5,925 housing units, 12% built before 1940 and 49% before 1980, with 26% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5586925, checked 2026-10-19).
Whitewater has 4 points fewer pre-1940 homes than Walworth County as a whole (16%) and 3 points more homes built after 2000 than the county's 23% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US55127, checked 2026-10-19).
The median Whitewater home was built in 1981 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US5586925, checked 2026-10-19) and the median home has 4.5 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US5586925, checked 2026-10-19).

That -5F figure is the Walworth County cold-day number a Whitewater 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 67% of Whitewater on gas and 31% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Whitewater home has 4.5 rooms and was built around 1981, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
