Of the 14,276 occupied homes in Glastonbury, 51% heat with natural gas, 34% with heating oil, 8% with electricity and 5% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US0911031240, checked 2026-10-19).
Glastonbury has 3 points more oil heat than Capitol Planning Region as a whole, where 31% of homes burn oil, and 8 points less electric heat than the county's 16% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US09110, checked 2026-10-19).
Gas leads in Glastonbury at 51%, but 38% of homes still burn delivered oil or propane, and those 5,425 or so homes are where a heat pump pays back fastest.
The median Glastonbury home was built in 1976 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US0911031240, checked 2026-10-19) and the median home has 6.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US0911031240, checked 2026-10-19).
Glastonbury has 14,606 housing units, 8% built before 1940 and 57% before 1980, with 13% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US0911031240, checked 2026-10-19).
Glastonbury has 10 points fewer pre-1940 homes than Capitol Planning Region as a whole (18%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US09110, checked 2026-10-19).
75% of Glastonbury homes are single-family detached, 6% are in two- to four-unit buildings and 10% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US0911031240, checked 2026-10-19).
With 75% detached houses and 6% in small multi-family buildings, a Glastonbury quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 17% of Glastonbury homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US0911031240, checked 2026-10-19), the landlord signs the quote in many of them.
Glastonbury has 18 points more detached houses than Capitol Planning Region overall (57%) and 11 points fewer five-plus-unit buildings than the county's 21% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US09110, checked 2026-10-19).
No electric utility is on file for Glastonbury on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Energize CT residential heat pump rebate, run by Energize CT, is a live program for Connecticut addresses and publishes its terms without one headline figure (registry row 3 verified 2026-10-15, https://www.energizect.com/node/68091, checked 2026-10-16); confirm eligibility for the Glastonbury address before counting it. With 8% of Glastonbury homes already on electric heat and 90% 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 Glastonbury is $157,192 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US0911031240, 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 0F figure is the Hartford County cold-day number a Glastonbury heat pump is sized against, so ask the installer to show the system's heating output at 0F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 51% of Glastonbury on gas and 8% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Glastonbury home has 6.9 rooms and was built around 1976, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
