Thurmont is about 48 miles from the Census center point for Baltimore in a straight line and covers 3.116 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 2,415 occupied homes in Thurmont, 2% heat with natural gas, 12% with heating oil, 76% with electricity and 7% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2477825, checked 2026-10-19).
Electricity already heats 76% of Thurmont homes, ahead of oil at 12%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Thurmont has 4 points more oil heat than Frederick County as a whole, where 8% of homes burn oil, and 25 points more electric heat than the county's 51% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US24021, checked 2026-10-19).
Thurmont has 2,498 housing units, 13% built before 1940 and 42% before 1980, with 15% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2477825, checked 2026-10-19).
Thurmont has 17 points fewer homes built after 2000 than the county's 32% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US24021, checked 2026-10-19).
The median Thurmont home was built in 1987 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2477825, checked 2026-10-19) and the median home has 6.3 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US2477825, checked 2026-10-19).
67% of Thurmont homes are single-family detached, 5% are in two- to four-unit buildings and 14% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US2477825, checked 2026-10-19).
27% of Thurmont homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2477825, checked 2026-10-19), so beside the 67% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Thurmont has 7 points more detached houses than Frederick County overall (60%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US24021, checked 2026-10-19).
No electric utility is on file for Thurmont 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 Thurmont is $98,125 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US2477825, 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.

That 8F figure is the Frederick County cold-day number a Thurmont heat pump is sized against, so ask the installer to show the system's heating output at 8F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Thurmont home has 6.3 rooms and was built around 1987, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
