The quote form takes a ZIP code; for Niwot that is 80544 (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 1,505 occupied homes in Niwot, 76% heat with natural gas, 0% with heating oil, 16% with electricity and 8% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0853780, checked 2026-10-19).
Gas heats 76% of Niwot against electricity at 16%, 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.
Niwot has about the Boulder County oil share of 0% and 9 points less electric heat than the county's 25% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US08013, checked 2026-10-19).
Niwot has 1,526 housing units, 1% built before 1940 and 39% before 1980, with 6% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0853780, checked 2026-10-19).
Niwot has 5 points fewer pre-1940 homes than Boulder County as a whole (6%) and 20 points fewer homes built after 2000 than the county's 26% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US08013, checked 2026-10-19).
The median Niwot home was built in 1983 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0853780, checked 2026-10-19) and the median home has 7.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0853780, checked 2026-10-19).
74% of Niwot homes are single-family detached, 3% are in two- to four-unit buildings and 19% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0853780, checked 2026-10-19).
With 74% detached houses and 3% in small multi-family buildings, a Niwot quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 23% of Niwot homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0853780, checked 2026-10-19), the landlord signs the quote in many of them.
Niwot has 17 points more detached houses than Boulder County overall (57%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US08013, checked 2026-10-19).
No electric utility is on file for Niwot on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Colorado Heat Pump Tax Credit (HPTC), run by Colorado Energy Office, is a live program for Colorado addresses and lists a standard figure of $1,000 (registry row 4 verified 2026-10-15, https://energyoffice.colorado.gov/hptc, checked 2026-10-16); confirm eligibility for the Niwot address before counting it. With 16% of Niwot homes already on electric heat and 84% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Median household income in Niwot is $146,492 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0853780, 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: -2F.

That -2F figure is the Boulder County cold-day number a Niwot heat pump is sized against, so ask the installer to show the system's heating output at -2F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 76% of Niwot on gas and 16% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Niwot home has 7.2 rooms and was built around 1983, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
