Why this number

In Utah, the cheapest heat last winter was natural gas at about $11.05 per million Btu delivered, then a cold-climate heat pump at $17.81 and propane at $27.24; electric resistance was the most expensive at $38.66 (EIA average prices, October 2025–March 2026, converted with the site’s standard efficiencies). For this winter EIA’s September outlook moves national heating oil +35%, natural gas -10%, propane -5% and electricity +3%; applied to Utah’s own prices, natural gas stays cheapest at about $9.98. The calculator below ranks every option from the prices on your bills.

Utah paid 13.19¢/kWh for electricity last winter — 6 of 35 on this list of 35 cold-weather states — and $1.05 per therm for gas (7 of 35); propane ran $2.29/gal (14 of 35) and heating oil $3.94/gal (19 of 35). Put on one basis, dollars per million Btu delivered, natural gas was the cheapest heat at $11.05 and electric resistance the dearest at $38.66 — a 28-dollar gap per MMBtu, or about $1,656 over a 60-MMBtu season.

Price basis: Utah’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.

Utah heating cost per MMBtu, fuel by fuel

Utah heating cost per million Btu delivered by fuel, last winter measured and this winter estimated
Heating option $/MMBtu delivered, last winter Season cost at 60 MMBtu This winter, EIA outlook applied
Natural gas furnace (95% AFUE) $11.05 $663 $9.98 (-10%)
Propane furnace (92% AFUE) $27.24 $1,634 $25.96 (-5%)
Heating oil boiler (85% AFUE) $33.47 $2,008 $45.02 (+35%)

Heat pump at 17°F (COP 2.17, NEEP median 3-ton ducted) $17.81 $1,069 $18.27 (+3%)
Heat pump at 5°F (COP 1.90) $20.35 $1,221 $20.87 (+3%)
Electric resistance (COP 1.00) $38.66 $2,319 $39.66 (+3%)

The season column is an illustrative 60 MMBtu of delivered heat; in Utah that puts natural gas at $663 and electric resistance at $2,319 for the winter. The this-winter column applies EIA’s national STEO change per fuel to Utah’s own price (electricity +3%) — direction, not a state forecast.

The prices behind the table

Utah fuel and electricity prices behind the comparison, with source, basis and vintage
Price Last winter average (Oct 2025–Mar 2026) Latest published reading Source and basis
Electricity 13.19¢/kWh 13.12¢/kWh (July 2026) EIA Electric Power Monthly 5.6.A; winter average from the monthly editions
Natural gas $1.05/therm ($10.94/Mcf, 6 of 6 months reported) $11.84/Mcf (June 2026, shoulder-season price) EIA Natural Gas Monthly, residential price by state; 1 Mcf = 10.38 therms
Heating oil $3.94/gal $5.30/gal (STEO forecast, national) EIA STEO national average Oct 2025–Mar 2026 — no SHOPP state or regional heating oil series
Propane $2.29/gal $2.34/gal (week of 2026-03-30) EIA SHOPP weekly survey, Utah, Oct 2025–Mar 2026 average

Utah’s winter gas average ($10.94/Mcf) sits close to its June figure ($11.84), so the seasonal fixed-charge effect that distorts most states’ summer prices is small here.

What Utah’s utilities charge

Utah's largest electric utilities and what resistance and heat-pump heat cost at each one's average price
Utility (largest by customers) Residential customers ¢/kWh (EIA-861 2024) Resistance $/MMBtu Heat pump at 17°F $/MMBtu
PacifiCorp 947,246 12.5¢ $36.63 $16.88
Adjustment 2024 97,407 12.5¢ $36.63 $16.88
Provo City Corp 35,299 11.4¢ $33.41 $15.40

The statewide 13.19¢ hides a 1.1¢ spread between Utah’s largest utilities, worth $3.22 per MMBtu on resistance heat and $1.49 on a heat pump. The ZIP lookup finds yours.

How Utah homes are heated

Share of occupied housing units by main house-heating fuel in Utah and the US, ACS 2019–2023 5-year (table B25040), 1,094,896 Utah units
Main heating fuel Utah homes US homes
Natural gas (utility) 79.1% 46.8%
Electricity 16.4% 40.8%
Propane (bottled, tank or LP gas) 2.5% 4.9%
Heating oil or kerosene 0.1% 4.1%
Wood 0.8% 1.4%

Natural gas heats 79.1% of Utah’s 1,094,896 occupied homes against 46.8% nationally, with electricity at 16.4%, propane at 2.5% and heating oil at 0.1%. That lines up with the table above: natural gas was also Utah’s cheapest heat last winter at $11.05 per MMBtu.

What the numbers say about Utah

At last winter’s average prices, the cheapest way to heat a home in Utah was natural gas at about $11 per million Btu delivered, and the most expensive was electric resistance at $39 — a 3.5× spread between the two columns. Gas beat a cold-climate heat pump at 17°F (COP 2.17) by $6.76/MMBtu, and at 47°F (COP 3.2, $12.08) the heat pump still trails. At Utah’s winter rates the economic balance point lands above 47°F (COP 3.50 needed against 3.20 available), so the furnace is cheaper at every rated temperature. No EIA state or regional heating-oil series exists for Utah; the oil row is the national STEO average ($3.94/gal last winter, $5.30 forecast) and is labelled as such. Propane averaged $2.29/gal in the state survey, with a national -5% outlook for this winter.

Heating degree-days: Utah’s own figure and the EIA division forecast

Utah itself logged 4,523 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 Mountain census division degree-days, the only one with a forecast for the coming winter; it groups Utah with its neighbours and is not a Utah figure:

EIA STEO Mountain census division heating degree-days (not a state figure): last winter actual and this winter forecast, month by month
Last winter (actual) HDD This winter (STEO forecast) HDD
Oct 2025 311 Oct 2026 335
Nov 2025 483 Nov 2026 606
Dec 2025 643 Dec 2026 866
Jan 2026 800 Jan 2027 853
Feb 2026 547 Feb 2027 696
Mar 2026 355 Mar 2027 574
Oct–Mar total 3,138 Oct–Mar total 3,929

January in the EIA Mountain census division (the coarse series that groups Utah with its neighbours) averaged about 39°F last winter (65°F minus degree-days per day) and is forecast at 37°F for January 2027, a season move of +791 degree-days. Degree-days set how much heat Utah needs, the table above sets the price per unit, and the bill jump calculator multiplies the two.

Where the heat pump crosses over in Utah

At last winter’s averages of 13.19¢/kWh and $1.05/therm, a heat pump beats a 95% gas furnace whenever its COP exceeds 3.50. Utah’s economic balance point on the NEEP median curve is above 47°F (COP 3.50 needed against 3.20 available), so the furnace is cheaper at every rated temperature; the crossover tool runs seven named units at Utah’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 Utah fresh state propane readings on the weekly tracker .

Frequently asked questions

What is the cheapest way to heat a home in Utah?

On last winter’s EIA average prices, natural gas at about $11.05 per million Btu delivered, against a cold-climate heat pump at $17.81 and propane at $27.24. Utah’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 Utah’s fixed monthly charges and equipment prices sit outside it.

Is a heat pump cheaper than gas in Utah?

At Utah’s last-winter averages of 13.19¢/kWh and $1.05/therm, a heat pump needs a COP above 3.50 to beat a 95% furnace. Against Utah’s required COP 3.50, the NEEP medians (3.20/2.17/1.90 at 47/17/5°F) mean the heat pump loses at every rating point in Utah; the balance point is above 47°F (COP 3.50 needed against 3.20 available), so the furnace is cheaper at every rated temperature.

How much will heating oil and propane cost in Utah this winter?

Nobody publishes a Utah forecast; applying EIA’s September STEO national changes (+35% oil, -5% propane) to Utah’s last-winter $3.94 and $2.29 per gallon gives roughly $5.30 and $2.18 — the ’this winter’ column. Utah’s weekly SHOPP readings resume in October; the Winter Fuels Outlook (October 6) adds household expenditure on top.

Where do the Utah prices on this page come from?

13.19¢/kWh is the EIA Electric Power Monthly average for Utah over the October 2025–March 2026 editions (13.12¢ in July 2026); the share of homes on each heating fuel is Census ACS 2019–2023 5-year table B25040; $10.94/Mcf is the Natural Gas Monthly winter average (6 months), converted at 10.38 therms per Mcf; oil $3.94 and propane $2.29 per gallon are SHOPP season averages, regional or national where marked; degree-days are the STEO Mountain series. Only the ’this winter’ column is an estimate.

How we calculated this

Worked for Utah at last winter’s averages: gas 10 × $1.05 ÷ 0.95 = $11.05/MMBtu; propane 10 × ($2.29 ÷ 0.91452) ÷ 0.92 = $27.24; oil 10 × ($3.94 ÷ 1.385) ÷ 0.85 = $33.47; resistance 293.07 × 0.1319 = $38.66; heat pump $38.66 ÷ 2.17 = $17.81. 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).
