Model
Waykar CHWA120A
Rank #281 means 280 of the 519 dehumidifier models we track cost less to run each year; the 92nd efficiency percentile means it uses less energy for its size than 92% of those models.
What does the Waykar CHWA120A cost to run per year?
The Waykar CHWA120A holds rank #281 of 519 on running cost, at about $68 a year, an unremarkable but typical figure for the class. Few dehumidifier models we track beat it on size-adjusted efficiency; it edges out 92% of the class once capacity is normalized. Its IEF of 2.01 reflects integrated energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Garvee G-AD35PT at $68/yr runs a little cheaper and the Lg DT351BWR0 at $69/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 CHWA120A's $68/yr adds up to roughly $544 in electricity alone, before purchase price or repairs.
Also sold as: Aux ADT35V1.
By the numbers
The Waykar CHWA120A 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 $68/yr, here is what the Waykar CHWA120A 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 CHWA120A costs about $680. That is roughly $40 more than the class median, which would run closer to $640 over the same ten years.
How the Waykar CHWA120A compares
The dehumidifier class we track runs from $19 to $521 a year. At $68/yr, it runs about $4 a year above the class median of $64, and it is about $49 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 36.9 pints/day, the Waykar CHWA120A is a mid-size dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, 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. Its IEF of 2.01, 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). IEF measures liters of water removed per kilowatt-hour; a higher IEF means less energy per pint of moisture removed for a given capacity.
- Water removal capacity (pints/day). A dehumidifier rated to remove more pints per day is built for a larger space or a more humid room, and generally draws more power to do it.
- Humidistat accuracy. A unit with a more precise humidistat cycles the compressor off once the target humidity is reached, rather than running continuously.
Common questions
Is the Waykar CHWA120A cheap to run?
Roughly, yes. Its $68/yr figure is close to the class median, ranking #281 of 519, neither a bargain nor a splurge on running cost.
How much does the Waykar CHWA120A cost per month?
About $5.71 a month, which is the $68 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 369 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $68 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Waykar CHWA120A for its size?
92nd percentile once size is factored in, a fairly typical result for the class.
