Model
Professional Series® PS-UFR171
Rank #345 means 344 of the 622 freezer models we track cost less to run each year; the 81st efficiency percentile means it uses less energy for its size than 81% of those models.
What does the Professional Series® PS-UFR171 cost to run per year?
Do the math and the Professional Series® PS-UFR171's $81/yr puts it at rank #345 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 $90/yr to run, a saving of roughly $9 a year. Normalized for capacity, it ranks ahead of 81% of freezer models we track on efficiency, a genuinely strong showing. At 17 cu ft, it is a large 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 Gaggenau RF461705 at $81/yr runs a little cheaper and the Thermador T24IF905SP at $81/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 Professional Series® PS-UFR171's $81/yr adds up to roughly $1134 in electricity alone, before purchase price or repairs.
Also sold as: Black+Decker BUC1700XB.
By the numbers
The Professional Series® PS-UFR171 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 $81/yr, here is what the Professional Series® PS-UFR171 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Professional Series® PS-UFR171 costs about $810. That is roughly $90 less than a standard model in its class, which would run closer to $900 over the same ten years.
How the Professional Series® PS-UFR171 compares
The freezer class we track runs from $25 to $120 a year. At $81/yr, it runs about $6 a year above the class median of $75, and it is about $56 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $90/yr, the Professional Series® PS-UFR171 uses 10% less energy.
What drives its running cost
At 17 cu ft, the Professional Series® PS-UFR171 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. 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 Professional Series® PS-UFR171 cheap to run?
It is about average. At $81 a year it ranks #345 of 622 freezer models we track, close to the middle of its class on running cost.
How much does the Professional Series® PS-UFR171 cost per month?
Roughly $6.73/mo, spreading the $81/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 435 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $81 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Professional Series® PS-UFR171 for its size?
81st percentile once size is factored in, a fairly typical result for the class.
