Wilmington / Glasgow
Glasgow is about 15 miles from the Census center point for Wilmington in a straight line and covers 9.925 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).
Glasgow has 15,546 residents (give or take 2,077) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1029350, checked 2026-10-19), about 1,566 people per square mile.
The quote form takes a ZIP code; for Glasgow that is 19702 (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 5,690 occupied homes in Glasgow, 49% heat with natural gas, 11% with heating oil, 35% with electricity and 4% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1029350, checked 2026-10-19).
Glasgow has about the New Castle County oil share of 9% and 3 points more electric heat than the county's 32% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US10003, checked 2026-10-19).
Gas heats 49% of Glasgow against electricity at 35%, 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.
The median Glasgow home was built in 1993 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1029350, checked 2026-10-19) and the median home has 6.8 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1029350, checked 2026-10-19).
Glasgow has 5,792 housing units, 1% built before 1940 and 17% before 1980, with 29% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1029350, checked 2026-10-19).
Glasgow has 10 points fewer pre-1940 homes than New Castle County as a whole (11%) and 9 points more homes built after 2000 than the county's 20% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US10003, checked 2026-10-19).
63% of Glasgow homes are single-family detached, 1% are in two- to four-unit buildings and 6% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1029350, checked 2026-10-19).
16% of Glasgow homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1029350, checked 2026-10-19), so beside the 63% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Glasgow has 10 points more detached houses than New Castle County overall (53%) and 13 points fewer five-plus-unit buildings than the county's 19% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US10003, checked 2026-10-19).
No electric utility is on file for Glasgow 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 Glasgow is $113,982 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1029350, 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: 11F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), New Castle County row, 99% heating, PDF page 17 of 141 (Revised 11/11/2020), https://www.energystar.gov/sites/default/files/Design%20Temperature%20Limit%20Reference%20Guide%20(2019%20Ed)%20-%20ENERGY%20STAR%20Single-Family%20New%20Homes_Rev11.pdf, fetched 2026-10-19, 99%.
That 11F figure is the New Castle County cold-day number a Glasgow heat pump is sized against, so ask the installer to show the system's heating output at 11F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 49% of Glasgow on gas and 35% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Glasgow home has 6.8 rooms and was built around 1993, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
