Model
Waykar CHWA80E
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 CHWA80E cost to run per year?
The Waykar CHWA80E costs about $48 a year to run and sits near the top of the cheapest-to-run leaderboard, rank #96 of 519. Its 70th size-adjusted efficiency percentile is a step ahead of the class median, though not among the very top results. Its IEF of 1.9 reflects integrated energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Waykar CHWA80B at $48/yr runs a little cheaper and the Ludatido PD10C2-25 at $49/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 CHWA80E's $48/yr adds up to roughly $384 in electricity alone, before purchase price or repairs.
Also sold as: Waykar CHWA80A.
By the numbers
The Waykar CHWA80E 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 CHWA80E 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 CHWA80E 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 CHWA80E 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 CHWA80E 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 1.9, below 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 CHWA80E 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 CHWA80E 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 CHWA80E 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.
