Model
Conserv FR1700ER
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 Conserv FR1700ER cost to run per year?
Ranking #345 of 622, the Conserv FR1700ER runs at roughly $81 a year, neither the cheapest nor the priciest in its class. 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 Conserv FR1700EL at $81/yr runs a little cheaper and the Conserv FR1700SREV 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 Conserv FR1700ER'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 Conserv FR1700ER 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 Conserv FR1700ER adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Conserv FR1700ER 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 Conserv FR1700ER 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 Conserv FR1700ER uses 10% less energy.
What drives its running cost
At 17 cu ft, the Conserv FR1700ER is a large freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, and larger freezer models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light.
- 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 Conserv FR1700ER 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 Conserv FR1700ER 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 Conserv FR1700ER for its size?
81st percentile once size is factored in, a fairly typical result for the class.
