Model
Hestan KRCF36
Rank #606 means 605 of the 622 freezer models we track cost less to run each year; the 50th efficiency percentile means it uses less energy for its size than 50% of those models.
What does the Hestan KRCF36 cost to run per year?
Out of the 622 freezer models we track, the Hestan KRCF36 lands at rank #606 on cost, roughly $117 a year, one of the most expensive figures in the class. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $128/yr to run, a saving of roughly $11 a year. Capacity-normalized, it ranks ahead of 50% of freezer models we track, right in the class's middle band. This class has no published efficiency-factor figure beyond annual kWh itself, so at 20 cu ft (the class spans 1.1 to 23), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Hallman HRBIAF36PR at $117/yr runs a little cheaper and the Ilve UFFC36SINPRY at $117/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A freezer typically stays in service for somewhere around 14 years; over that span, the Hestan KRCF36's $117/yr adds up to roughly $1638 in electricity alone, before purchase price or repairs.

By the numbers
The Hestan KRCF36 normalized against its whole class, so each figure means something.
What it costs you over time
Running cost is an every-year number, so it compounds. At $117/yr, here is what the Hestan KRCF36 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Hestan KRCF36 costs about $1170. That is roughly $110 less than a standard model in its class, which would run closer to $1280 over the same ten years.
How the Hestan KRCF36 compares
The freezer class we track runs from $25 to $120 a year. At $117/yr, it runs about $42 a year above the class median of $75, and it is about $92 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $128/yr, the Hestan KRCF36 uses 10% less energy.
What drives its running cost
At 20 cu ft, the Hestan KRCF36 is a large freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, size is usually the single biggest lever behind a running-cost figure, and at this end of the range there is more capacity to service, which tends to push the number up.
- Interior volume. As with refrigerators, more cubic feet of frozen storage generally means a bigger compressor and a higher annual energy figure.
- Insulation and defrost type. Better-insulated cabinets lose less cold to the surrounding room, and frost-free (automatic-defrost) freezers run a periodic heating element that a manual-defrost model does not.
- Chest vs upright design. Door orientation affects how much cold air escapes per opening: top-opening chest designs generally hold cold better than front-opening upright ones.
Common questions
Is the Hestan KRCF36 cheap to run?
Its $117/yr running cost, rank #606 of 622, is above what most freezer models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Hestan KRCF36 cost per month?
About $9.74 a month, which is the $117 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 630 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $117 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Hestan KRCF36 for its size?
50th percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
