Why this number
New Hampshire paid 26.78¢/kWh for electricity last winter — 30 of 35 on this list of 35 cold-weather states — and $1.90 per therm for gas (33 of 35); propane ran $3.58/gal (30 of 35) and heating oil $3.90/gal (17 of 35). Put on one basis, dollars per million Btu delivered, natural gas was the cheapest heat at $20.00 and electric resistance the dearest at $78.48 — a 58-dollar gap per MMBtu, or about $3,509 over a 60-MMBtu season.
Price basis: New Hampshire’s fuel prices are last winter’s measured EIA and SHOPP averages; the this-winter column scales each by EIA’s national STEO change for that fuel — a labelled estimate, not a state forecast.
New Hampshire heating cost per MMBtu, fuel by fuel
| Heating option | $/MMBtu delivered, last winter | Season cost at 60 MMBtu | This winter, EIA outlook applied |
|---|---|---|---|
| Natural gas furnace (95% AFUE) | $20.00 | $1,200 | $18.05 (-10%) |
| Propane furnace (92% AFUE) | $42.55 | $2,553 | $40.56 (-5%) |
| Heating oil boiler (85% AFUE) | $33.11 | $1,987 | $44.54 (+35%) |
| Heat pump at 47°F (COP 3.20) | $24.53 | $1,472 | $25.16 (+3%) |
| Heat pump at 17°F (COP 2.17, NEEP median 3-ton ducted) | $36.17 | $2,170 | $37.10 (+3%) |
| Heat pump at 5°F (COP 1.90) | $41.31 | $2,478 | $42.38 (+3%) |
| Electric resistance (COP 1.00) | $78.48 | $4,709 | $80.52 (+3%) |
The season column is an illustrative 60 MMBtu of delivered heat; in New Hampshire that puts natural gas at $1,200 and electric resistance at $4,709 for the winter. The this-winter column applies EIA’s national STEO change per fuel to New Hampshire’s own price (oil +35% is the large one) — direction, not a state forecast.
The prices behind the table
| Price | Last winter average (Oct 2025–Mar 2026) | Latest published reading | Source and basis |
|---|---|---|---|
| Electricity | 26.78¢/kWh | 26.6¢/kWh (July 2026) | EIA Electric Power Monthly 5.6.A; winter average from the monthly editions |
| Natural gas | $1.90/therm ($19.76/Mcf, 6 of 6 months reported) | $21.67/Mcf (June 2026, shoulder-season price) | EIA Natural Gas Monthly, residential price by state; 1 Mcf = 10.38 therms |
| Heating oil | $3.90/gal | $5.41/gal (week of 2026-03-30) | EIA SHOPP weekly survey, New Hampshire, Oct 2025–Mar 2026 average |
| Propane | $3.58/gal | $3.78/gal (week of 2026-03-30) | EIA SHOPP weekly survey, New Hampshire, Oct 2025–Mar 2026 average |
New Hampshire’s winter gas average ($19.76/Mcf) sits close to its June figure ($21.67), so the seasonal fixed-charge effect that distorts most states’ summer prices is small here.
What New Hampshire’s utilities charge
| Utility (largest by customers) | Residential customers | ¢/kWh (EIA-861 2024) | Resistance $/MMBtu | Heat pump at 17°F $/MMBtu |
|---|---|---|---|---|
| Public Service Co of NH | 459,907 | 18.7¢ | $54.80 | $25.26 |
| Community Power Coalition of NH | 104,562 | 8.7¢ | $25.50 | $11.75 |
| New Hampshire Elec Coop Inc | 74,144 | 23.6¢ | $69.16 | $31.87 |
The statewide 26.78¢ hides a 14.9¢ spread between New Hampshire’s largest utilities, worth $43.67 per MMBtu on resistance heat and $20.12 on a heat pump. The ZIP lookup finds yours.
How New Hampshire homes are heated
| Main heating fuel | New Hampshire homes | US homes |
|---|---|---|
| Natural gas (utility) | 21.1% | 46.8% |
| Electricity | 10.7% | 40.8% |
| Propane (bottled, tank or LP gas) | 18.5% | 4.9% |
| Heating oil or kerosene | 40.8% | 4.1% |
| Wood | 6.0% | 1.4% |
Heating oil or kerosene heats 40.8% of New Hampshire’s 551,186 occupied homes against 4.1% nationally, with electricity at 10.7%, propane at 18.5% and heating oil at 40.8%. The table above says otherwise for last winter: the households on heating oil or kerosene paid about $33.11 per MMBtu while natural gas delivered the same heat for $20.00, a $13.11 gap on every million Btu.
What the numbers say about New Hampshire
At last winter’s average prices, the cheapest way to heat a home in New Hampshire was natural gas at about $20 per million Btu delivered, and the most expensive was electric resistance at $78 — a 3.9× spread between the two columns. Gas beat a cold-climate heat pump at 17°F (COP 2.17) by $16.17/MMBtu, and at 47°F (COP 3.2, $24.53) the heat pump still trails. At New Hampshire’s winter rates the economic balance point lands above 47°F (COP 3.92 needed against 3.20 available), so the furnace is cheaper at every rated temperature. Heating oil averaged $3.90/gal across 26 SHOPP survey weeks and finished the season at $5.41 on March 30, 2026; EIA’s September outlook puts national oil +35% for this winter, which would carry New Hampshire’s figure to roughly $45/MMBtu. Propane averaged $3.58/gal in the state survey, with a national -5% outlook for this winter.
Heating degree-days: New Hampshire’s own figure and the EIA division forecast
New Hampshire itself logged 6,287 population-weighted heating degree-days from October 2025 to March 2026 (NOAA Climate Prediction Center state series, base 65°F), against 3,500 for the contiguous US. The month-by-month table below is a different, coarser series — EIA STEO New England census division degree-days, the only one with a forecast for the coming winter; it groups New Hampshire with its neighbours and is not a New Hampshire figure:
| Last winter (actual) | HDD | This winter (STEO forecast) | HDD |
|---|---|---|---|
| Oct 2025 | 382 | Oct 2026 | 400 |
| Nov 2025 | 757 | Nov 2026 | 670 |
| Dec 2025 | 1,175 | Dec 2026 | 964 |
| Jan 2026 | 1,290 | Jan 2027 | 1,125 |
| Feb 2026 | 1,163 | Feb 2027 | 964 |
| Mar 2026 | 841 | Mar 2027 | 852 |
| Oct–Mar total | 5,608 | Oct–Mar total | 4,975 |
January in the EIA New England census division (the coarse series that groups New Hampshire with its neighbours) averaged about 23°F last winter (65°F minus degree-days per day) and is forecast at 29°F for January 2027, a season move of -633 degree-days. Degree-days set how much heat New Hampshire needs, the table above sets the price per unit, and the bill jump calculator multiplies the two.
Heating oil prices in New Hampshire
EIA’s weekly SHOPP survey priced residential No. 2 heating oil in New Hampshire at $3.54/gal in the first October week of the 2025-26 season and $5.41 in the final March week — a season average of $3.90, low $3.47, high $5.41, against a national average of $4.01. The survey resumes in October 2026; the weekly tracker carries every state.

Where the heat pump crosses over in New Hampshire
At last winter’s averages of 26.78¢/kWh and $1.90/therm, a heat pump beats a 95% gas furnace whenever its COP exceeds 3.92. New Hampshire’s economic balance point on the NEEP median curve is above 47°F (COP 3.92 needed against 3.20 available), so the furnace is cheaper at every rated temperature; the crossover tool runs seven named units at New Hampshire’s prices and the dual-fuel calculator turns the answer into a changeover setting.
From October 6 the EIA Winter Fuels Outlook adds household expenditure by region and the weekly SHOPP survey restarts, giving New Hampshire fresh state propane and heating-oil readings on the weekly tracker .
Frequently asked questions
What is the cheapest way to heat a home in New Hampshire?
On last winter’s EIA average prices, natural gas at about $20.00 per million Btu delivered, against heating oil at $33.11 and a cold-climate heat pump at $36.17. New Hampshire’s ranking uses a 95% gas furnace, 92% propane furnace, 85% oil boiler and a heat pump at COP 2.17; it is per unit of heat, so New Hampshire’s fixed monthly charges and equipment prices sit outside it.
Is a heat pump cheaper than gas in New Hampshire?
At New Hampshire’s last-winter averages of 26.78¢/kWh and $1.90/therm, a heat pump needs a COP above 3.92 to beat a 95% furnace. Against New Hampshire’s required COP 3.92, the NEEP medians (3.20/2.17/1.90 at 47/17/5°F) mean the heat pump loses at every rating point in New Hampshire; the balance point is above 47°F (COP 3.92 needed against 3.20 available), so the furnace is cheaper at every rated temperature.
How much will heating oil and propane cost in New Hampshire this winter?
Nobody publishes a New Hampshire forecast; applying EIA’s September STEO national changes (+35% oil, -5% propane) to New Hampshire’s last-winter $3.90 and $3.58 per gallon gives roughly $5.24 and $3.41 — the ’this winter’ column. New Hampshire’s weekly SHOPP readings resume in October; the Winter Fuels Outlook (October 6) adds household expenditure on top.
Where do the New Hampshire prices on this page come from?
26.78¢/kWh is the EIA Electric Power Monthly average for New Hampshire over the October 2025–March 2026 editions (26.6¢ in July 2026); the share of homes on each heating fuel is Census ACS 2019–2023 5-year table B25040; $19.76/Mcf is the Natural Gas Monthly winter average (6 months), converted at 10.38 therms per Mcf; oil $3.90 and propane $3.58 per gallon are SHOPP state season averages; degree-days are the STEO New England series. Only the ’this winter’ column is an estimate.
How we calculated this
Worked for New Hampshire at last winter’s averages: gas 10 × $1.90 ÷ 0.95 = $20.00/MMBtu; propane 10 × ($3.58 ÷ 0.91452) ÷ 0.92 = $42.55; oil 10 × ($3.90 ÷ 1.385) ÷ 0.85 = $33.11; resistance 293.07 × 0.2678 = $78.48; heat pump $78.48 ÷ 2.17 = $36.17. The this-winter column multiplies each by EIA’s national STEO change for that fuel (electricity ×1.026, gas ×0.903, propane ×0.953, oil ×1.345).Sources: U.S. Energy Information Administration (EIA) electricity rates · DSIRE incentive records · public IRS/OBBBA guidance.
