Model
Aeocky RHEA-RCS25(Y)-N4-3-25
Rank #188 means 187 of the 519 dehumidifier models we track cost less to run each year; the 35th efficiency percentile means it uses less energy for its size than 35% of those models.
What does the Aeocky RHEA-RCS25(Y)-N4-3-25 cost to run per year?
Ranking #188 of 519, the Aeocky RHEA-RCS25(Y)-N4-3-25 is in the cheaper half of its class to run, at about $53 a year. Normalized for capacity, it beats only 35% of dehumidifier models we track, a below-average efficiency result. At a IEF of 1.86, its integrated energy factor is the single figure that best explains how it earns its running-cost number.
Immediately around it on the leaderboard, the Moiswell Defender SP60R at $53/yr runs a little cheaper and the Easykey AQUA-RCS25 (Y)-N4-3-25 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 Aeocky RHEA-RCS25(Y)-N4-3-25's $53/yr adds up to roughly $424 in electricity alone, before purchase price or repairs.
Also sold as: Arecovas AR-DF006.
By the numbers
The Aeocky RHEA-RCS25(Y)-N4-3-25 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 $53/yr, here is what the Aeocky RHEA-RCS25(Y)-N4-3-25 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Aeocky RHEA-RCS25(Y)-N4-3-25 costs about $530. That is roughly $110 less than the class median, which would run closer to $640 over the same ten years.
How the Aeocky RHEA-RCS25(Y)-N4-3-25 compares
The dehumidifier class we track runs from $19 to $521 a year. At $53/yr, it runs about $11 a year cheaper than the class median of $64, and it is about $34 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 24.5 pints/day, the Aeocky RHEA-RCS25(Y)-N4-3-25 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 1.86, 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 Aeocky RHEA-RCS25(Y)-N4-3-25 cheap to run?
Yes, relatively. At $53 a year it ranks #188 of 519 dehumidifier models we track, in the cheaper part of its class to run.
How much does the Aeocky RHEA-RCS25(Y)-N4-3-25 cost per month?
Roughly $4.41/mo, spreading the $53/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 285 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $53 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Aeocky RHEA-RCS25(Y)-N4-3-25 for its size?
35th percentile once size is factored in, a fairly typical result for the class.
