Model
Waykar; Kesnos; Yaufey; Fehom YDZ-80
Rank #155 means 154 of the 519 dehumidifier models we track cost less to run each year; the 26th efficiency percentile means it uses less energy for its size than 26% of those models.
What does the Waykar; Kesnos; Yaufey; Fehom YDZ-80 cost to run per year?
Do the math and the Waykar; Kesnos; Yaufey; Fehom YDZ-80's $52/yr puts it at rank #155 of 519, on the cheaper side of the class. Adjusted for size, it is only more efficient than 26% of dehumidifier models we track, so part of its running cost comes from its capacity rather than efficiency alone. The IEF figure of 1.76 on this model captures integrated energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Waykar; Kesnos; Yaufey; Fehom YDY-80 at $52/yr runs a little cheaper and the Whirlpool WHAD251AW at $53/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A dehumidifier typically stays in service for somewhere around 8 years; over that span, the Waykar; Kesnos; Yaufey; Fehom YDZ-80's $52/yr adds up to roughly $416 in electricity alone, before purchase price or repairs.
Also sold as: Waykar; Kesnos; Yaufey; Fehom YDA-80.
By the numbers
The Waykar; Kesnos; Yaufey; Fehom YDZ-80 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 $52/yr, here is what the Waykar; Kesnos; Yaufey; Fehom YDZ-80 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Waykar; Kesnos; Yaufey; Fehom YDZ-80 costs about $520. That is roughly $120 less than the class median, which would run closer to $640 over the same ten years.
How the Waykar; Kesnos; Yaufey; Fehom YDZ-80 compares
The dehumidifier class we track runs from $19 to $521 a year. At $52/yr, it runs about $12 a year cheaper than the class median of $64, and it is about $33 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 24 pints/day, the Waykar; Kesnos; Yaufey; Fehom YDZ-80 is a small dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, 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. Beyond size, its IEF of 1.76, below the class median of 2.01, is the class's own efficiency yardstick, integrated energy factor, and it is what separates two similarly sized models with different running costs.
- Integrated Energy Factor (IEF). Two dehumidifiers rated for the same pints per day can carry very different IEF figures, and IEF is what actually separates their running costs.
- Water removal capacity (pints/day). Pints-per-day rating scales with the space it is built for, and that rating is the first driver of how much power the compressor needs.
- Humidistat accuracy. How tightly a humidistat holds its target humidity determines how much of the day the compressor actually runs, on top of the unit's rated capacity and IEF.
Common questions
Is the Waykar; Kesnos; Yaufey; Fehom YDZ-80 cheap to run?
Yes, relatively. At $52 a year it ranks #155 of 519 dehumidifier models we track, in the cheaper part of its class to run.
How much does the Waykar; Kesnos; Yaufey; Fehom YDZ-80 cost per month?
Roughly $4.36/mo, spreading the $52/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 282 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $52 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Waykar; Kesnos; Yaufey; Fehom YDZ-80 for its size?
26th percentile once size is factored in, a fairly typical result for the class.
