Danvers has 28,098 residents (give or take 33) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2500916250, checked 2026-10-19), about 2,116 people per square mile.
Danvers is about 17 miles from the Census center point for Boston in a straight line and covers 13.279 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).
The quote form takes a ZIP code; for Danvers that is 01923, 01937 (Census 2020 ZCTA to county subdivision relationship file, ZIP areas at least 20% inside the town, https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_cousub20_natl.txt, checked 2026-10-19).
Of the 11,005 occupied homes in Danvers, 49% heat with natural gas, 32% with heating oil, 15% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2500916250, checked 2026-10-19).
Gas leads in Danvers at 49%, but 34% of homes still burn delivered oil or propane, and those 3,742 or so homes are where a heat pump pays back fastest.
Danvers has 12 points more oil heat than Essex County as a whole, where 20% of homes burn oil, and 2 points less electric heat than the county's 17% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US25009, checked 2026-10-19).
Danvers has 11,536 housing units, 25% built before 1940 and 69% before 1980, with 17% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2500916250, checked 2026-10-19).
Danvers has 10 points fewer pre-1940 homes than Essex County as a whole (35%) and 4 points more homes built after 2000 than the county's 13% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US25009, checked 2026-10-19).
The median Danvers home was built in 1963 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2500916250, checked 2026-10-19) and the median home has 6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2500916250, checked 2026-10-19).
58% of Danvers homes are single-family detached, 11% are in two- to four-unit buildings and 24% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2500916250, checked 2026-10-19).
31% of Danvers homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2500916250, checked 2026-10-19), so beside the 58% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Danvers has 8 points more detached houses than Essex County overall (50%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US25009, checked 2026-10-19).
69% of Danvers homes were built before 1980 and only 17% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2500916250, checked 2026-10-19), so most of the stock predates modern insulation codes; the installer's heat-loss calculation, not a square-footage rule, decides the tonnage.
Danvers is also on the state table of towns served by a municipal light plant, Danvers Electric Division (Massachusetts municipally-owned electric companies, https://www.mass.gov/info-details/massachusetts-municipally-owned-electric-companies, checked 2026-10-19).
Mass Save heat pump rebates are for electric accounts with Cape Light Compact, Eversource, National Grid or Unitil, so a Danvers home billed by Danvers Electric Division asks the plant for its heat pump rebate instead.
Median household income in Danvers is $125,395 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2500916250, 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: 1F.

That 1F figure is the Essex County cold-day number a Danvers heat pump is sized against, so ask the installer to show the system's heating output at 1F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 49% of Danvers on gas and 15% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Danvers home has 6 rooms and was built around 1963, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
