Model
Wood'S WUF140SL
Rank #308 means 307 of the 622 freezer models we track cost less to run each year; the 68th efficiency percentile means it uses less energy for its size than 68% of those models.
What does the Wood'S WUF140SL cost to run per year?
Do the math and the Wood'S WUF140SL's $74/yr puts it at rank #308 of 622, right around the class average. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $82/yr to run, a saving of roughly $8 a year. Adjusted for size, it is more efficient than 68% of freezer models we track, a solidly above-average result. At 14.1 cu ft, it is a mid-size freezer for the class, which runs 1.1 to 23 cu ft; size and efficiency are the two levers behind the figure above, and this dataset does not carry a separate efficiency-factor column for this class.
Immediately around it on the leaderboard, the Fisher & Paykel RS24F*E* at $74/yr runs a little cheaper and the Wood'S WUF140W at $74/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 Wood'S WUF140SL's $74/yr adds up to roughly $1036 in electricity alone, before purchase price or repairs.
Also sold as: Wood'S WUF140W.
By the numbers
The Wood'S WUF140SL 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 $74/yr, here is what the Wood'S WUF140SL adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Wood'S WUF140SL costs about $740. That is roughly $80 less than a standard model in its class, which would run closer to $820 over the same ten years.
How the Wood'S WUF140SL compares
The freezer class we track runs from $25 to $120 a year. At $74/yr, it runs about $1 a year cheaper than the class median of $75, and it is about $49 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $82/yr, the Wood'S WUF140SL uses 10% less energy.
What drives its running cost
At 14.1 cu ft, the Wood'S WUF140SL is a mid-size freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, putting it squarely in the middle of the class on the size lever that drives most of the cost.
- Interior volume. Cubic feet of frozen storage is the first lever behind a freezer's running cost, ahead of insulation or defrost type.
- Insulation and defrost type. Two freezers of the same size can differ meaningfully on running cost based on insulation quality and whether they run an automatic-defrost heater.
- Chest vs upright design. Chest freezers open from the top, so cold air, which sinks, stays inside when the lid opens; upright freezers lose more cold air per door opening for a similar capacity.
Common questions
Is the Wood'S WUF140SL cheap to run?
It is about average. At $74 a year it ranks #308 of 622 freezer models we track, close to the middle of its class on running cost.
How much does the Wood'S WUF140SL cost per month?
Roughly $6.16/mo, spreading the $74/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 398 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $74 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Wood'S WUF140SL for its size?
68th percentile once size is factored in, a fairly typical result for the class.
