Model
Waykar CHWA80A
Rank #96 means 95 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 CHWA80A cost to run per year?
At $48 a year to run, the Waykar CHWA80A is among the cheapest dehumidifier models we track, ranking #96 of 519. Once capacity is factored in, its 70th efficiency percentile puts it ahead of most peers in its class. The IEF figure of 1.9 on this model captures integrated energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Zunmos AS-CSJ72XK-5WT-OL at $48/yr runs a little cheaper and the Waykar CHWA80B at $48/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 CHWA80A's $48/yr adds up to roughly $384 in electricity alone, before purchase price or repairs.
Also sold as: Waykar CHWA80B, Waykar CHWA80E.
By the numbers
The Waykar CHWA80A 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 $48/yr, here is what the Waykar CHWA80A 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 CHWA80A costs about $480. That is roughly $160 less than the class median, which would run closer to $640 over the same ten years.
How the Waykar CHWA80A compares
The dehumidifier class we track runs from $19 to $521 a year. At $48/yr, it runs about $16 a year cheaper than the class median of $64, and it is about $29 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 24.91 pints/day, the Waykar CHWA80A 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, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class. Beyond size, its IEF of 1.9, 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 CHWA80A cheap to run?
Yes, relatively. At $48 a year it ranks #96 of 519 dehumidifier models we track, in the cheaper part of its class to run.
How much does the Waykar CHWA80A cost per month?
Roughly $4.02/mo, spreading the $48/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 260 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $48 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Waykar CHWA80A 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.
