Model
Waykar; Kesnos; Yaufey; Fehom YDW-150PM
Rank #425 means 424 of the 519 dehumidifier models we track cost less to run each year; the 70th efficiency percentile means it uses less energy for its size than 70% of those models.
What does the Waykar; Kesnos; Yaufey; Fehom YDW-150PM cost to run per year?
The Waykar; Kesnos; Yaufey; Fehom YDW-150PM costs about $97 a year to run, sitting well up the cheapest-to-run leaderboard, rank #425 of 519. Once capacity is factored in, its 70th efficiency percentile puts it ahead of most peers in its class. The IEF figure of 2.02 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 YDW-150 at $97/yr runs a little cheaper and the Keystone KSTAD504G at $97/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 YDW-150PM's $97/yr adds up to roughly $776 in electricity alone, before purchase price or repairs.
Also sold as: Waykar, Kesnos, Yaufey, Fehom YDY-150.
By the numbers
The Waykar; Kesnos; Yaufey; Fehom YDW-150PM 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 $97/yr, here is what the Waykar; Kesnos; Yaufey; Fehom YDW-150PM 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 YDW-150PM costs about $970. That is roughly $330 more than the class median, which would run closer to $640 over the same ten years.
How the Waykar; Kesnos; Yaufey; Fehom YDW-150PM compares
The dehumidifier class we track runs from $19 to $521 a year. At $97/yr, it runs about $33 a year above the class median of $64, and it is about $78 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 50 pints/day, the Waykar; Kesnos; Yaufey; Fehom YDW-150PM is a large dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, 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. Its IEF of 2.02, above the class median of 2.01, reflects integrated energy factor: a higher figure means it wrings more useful work out of every kilowatt-hour, so it is the efficiency lever to weigh against raw size.
- 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 YDW-150PM cheap to run?
Not especially. At $97 a year it ranks #425 of 519 dehumidifier models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Waykar; Kesnos; Yaufey; Fehom YDW-150PM cost per month?
Roughly $8.07/mo, spreading the $97/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 522 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $97 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 YDW-150PM for its size?
70th 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.
