Norwell in Plymouth County

Norwell has 11,361 residents (give or take 30) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2502350145, checked 2026-10-19), about 542 people per square mile.

Norwell is about 16 miles from the Census center point for Boston in a straight line and covers 20.942 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 Norwell that is 02061 (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).

Fuel mix

Of the 3,685 occupied homes in Norwell, 39% heat with natural gas, 47% with heating oil, 6% with electricity and 7% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2502350145, checked 2026-10-19).

Heating oil is the largest single fuel in Norwell at 47%, ahead of gas at 39%, so the usual job here is an oil boiler or furnace coming out and a cold-climate heat pump going in, with the oil tank removed.

Norwell has 15 points more oil heat than Plymouth County as a whole, where 32% of homes burn oil, and 6 points less electric heat than the county's 12% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US25023, checked 2026-10-19).

Housing stock

Norwell has 3,827 housing units, 18% built before 1940 and 68% before 1980, with 17% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2502350145, checked 2026-10-19).

Norwell has 3 points fewer pre-1940 homes than Plymouth County as a whole (21%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US25023, checked 2026-10-19).

The median Norwell home was built in 1968 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2502350145, checked 2026-10-19) and the median home has 7.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2502350145, checked 2026-10-19).

91% of Norwell homes are single-family detached, 2% are in two- to four-unit buildings and 3% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2502350145, checked 2026-10-19).

With 91% detached houses and 2% in small multi-family buildings, a Norwell quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 8% of Norwell homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2502350145, checked 2026-10-19), the landlord signs the quote in many of them.

Norwell has 21 points more detached houses than Plymouth County overall (70%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US25023, checked 2026-10-19).

Only 8% of Norwell homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2502350145, checked 2026-10-19), so nearly every quote here is the resident talking to the installer directly, and the rebate goes to the person living in the house.

Only 17% of Norwell homes are new enough to pass the whole-home rebate's weatherization check on age, and 18% date from before 1940, so most of the other 83% show it with a home energy assessment before the heat pump goes in.

Rebate path

No electric utility is on file for Norwell on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.

If the Norwell electric bill comes from one of the Mass Save sponsors (Cape Light Compact, Eversource, National Grid, Unitil), the whole-home heat pump rebate is $2,650 per ton up to $8,500, and the partial-home rebate is $1,125 per ton up to $8,500; for projects installed on or after January 1, 2027, the whole-home figure drops to $2,350 per ton capped at $7,500 (Mass Save air-source heat pump rebates, https://www.masssave.com/residential/rebates-offers-services/heating-and-cooling/heat-pumps/air-source-heat-pumps, checked 2026-10-19).

Median household income in Norwell is $188,699 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2502350145, checked 2026-10-19); Mass Save's enhanced heat pump incentives are income-based and decided household by household, so the town median only hints at how many neighbors qualify.

Cold-day number

Heating design temperature: 9F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Plymouth County row, 99% heating, PDF page 56 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 9F figure is the Plymouth County cold-day number a Norwell heat pump is sized against, so ask the installer to show the system's heating output at 9F, not at the milder rating-label temperature.

Next step

Ask what happens to the oil tank, since 47% of the 3,685 occupied Norwell homes have one and removal is usually a separate line on the quote.

Ask for the heat-loss calculation room by room; the median Norwell home has 7.6 rooms and was built around 1968, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
