Model
Liebherr HW 8000
Rank #25 means 24 of the 1,000 refrigerator models we track cost less to run each year; the 96th efficiency percentile means it uses less energy for its size than 96% of those models.
What does the Liebherr HW 8000 cost to run per year?
Almost nothing we track in this class costs less to run than the Liebherr HW 8000: about $29 a year, rank #25 of 1,000. It uses 32% less energy than the U.S. federal standard model in its class, which would cost about $42/yr to run, a saving of roughly $13 a year. Adjusted for its size, it is more efficient than 96% of refrigerator models we track, one of the strongest results in the whole class. Its listing marks it counter-depth, meaning it sits nearly flush with surrounding cabinets rather than protruding a few extra inches like a standard-depth model; that shallower body usually means less interior volume for the same footprint.
Immediately around it on the leaderboard, the Jennair JBWFNR18RX at $28/yr runs a little cheaper and the Xo XOU24WDZGBL at $29/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A refrigerator typically stays in service for somewhere around 12 years; over that span, the Liebherr HW 8000's $29/yr adds up to roughly $348 in electricity alone, before purchase price or repairs.
By the numbers
The Liebherr HW 8000 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 $29/yr, here is what the Liebherr HW 8000 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Liebherr HW 8000 costs about $290. That is roughly $130 less than a standard model in its class, which would run closer to $420 over the same ten years.
How the Liebherr HW 8000 compares
The refrigerator class we track runs from $8 to $149 a year. At $29/yr, it runs about $35 a year cheaper than the class median of $64, and it is about $21 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $42/yr, the Liebherr HW 8000 uses 32% less energy.
What drives its running cost
At 9 cu ft, the Liebherr HW 8000 is a mid-size refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, neither the size advantage of a small unit nor the size penalty of a large one applies here, so its running cost is a fairer test of efficiency alone.
- Counter depth vs standard depth. Counter-depth models sit flush with cabinets but usually hold less interior volume than a standard-depth model of the same width, which can nudge the per-cubic-foot running cost either way.
- Interior volume. Cubic feet of interior volume is the first thing that scales a fridge's running cost up or down, before compressor quality even enters the picture.
- Compressor technology. Newer variable-speed (inverter) compressors modulate output instead of cycling fully on and off, which tends to use less energy for the same cooling job than an older fixed-speed compressor.
- Placement and ventilation. A fridge pushed tight against a wall or cabinet, or standing next to an oven or in direct sun, works harder to shed the heat its compressor produces, which can push real-world cost above the published figure.
Common questions
Is the Liebherr HW 8000 cheap to run?
Yes, relatively. At $29 a year it ranks #25 of 1,000 refrigerator models we track, in the cheaper part of its class to run.
How much does the Liebherr HW 8000 cost per month?
Roughly $2.4/mo, spreading the $29/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 155 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $29 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Liebherr HW 8000 for its size?
96th 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.
