Model
U-Line UHFZ124-BS01B
Rank #208 means 207 of the 622 freezer models we track cost less to run each year; the 7th efficiency percentile means it uses less energy for its size than 7% of those models.
What does the U-Line UHFZ124-BS01B cost to run per year?
The U-Line UHFZ124-BS01B is a relatively cheap runner for its class: about $72 a year, rank #208 of 622. It uses 11% less energy than the U.S. federal standard model in its class, which would cost about $81/yr to run, a saving of roughly $9 a year. Its 7th size-adjusted efficiency percentile is well below the class median, worth weighing against the raw cost figure above. At 4.8 cu ft, it is a small 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 U-Line FZ124 at $72/yr runs a little cheaper and the U-Line UHFZ124-IS01B at $72/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 U-Line UHFZ124-BS01B's $72/yr adds up to roughly $1008 in electricity alone, before purchase price or repairs.
Also sold as: U-Line 1224FZRA.
By the numbers
The U-Line UHFZ124-BS01B 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 $72/yr, here is what the U-Line UHFZ124-BS01B adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the U-Line UHFZ124-BS01B costs about $720. That is roughly $90 less than a standard model in its class, which would run closer to $810 over the same ten years.
How the U-Line UHFZ124-BS01B compares
The freezer class we track runs from $25 to $120 a year. At $72/yr, it runs about $3 a year cheaper than the class median of $75, and it is about $47 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $81/yr, the U-Line UHFZ124-BS01B uses 11% less energy.
What drives its running cost
At 4.8 cu ft, the U-Line UHFZ124-BS01B is a small freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is.
- 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 U-Line UHFZ124-BS01B cheap to run?
Yes, relatively. At $72 a year it ranks #208 of 622 freezer models we track, in the cheaper part of its class to run.
How much does the U-Line UHFZ124-BS01B cost per month?
Roughly $6.03/mo, spreading the $72/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 390 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $72 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the U-Line UHFZ124-BS01B for its size?
7th percentile once size is factored in, a fairly typical result for the class.
