Model
Aeocky RHEA-RCS32(Y)-N4-3
Rank #246 means 245 of the 519 dehumidifier models we track cost less to run each year; the 48th efficiency percentile means it uses less energy for its size than 48% of those models.
What does the Aeocky RHEA-RCS32(Y)-N4-3 cost to run per year?
Do the math and the Aeocky RHEA-RCS32(Y)-N4-3's $63/yr puts it at rank #246 of 519, right around the class average. Adjusted for size, it is more efficient than 48% of dehumidifier models we track, a middling result. The IEF figure of 2.09 on this model captures integrated energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Arecovas AR-DF005 at $63/yr runs a little cheaper and the Yoau; Shinco; Uhome SDZ1-120P at $63/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-RCS32(Y)-N4-3's $63/yr adds up to roughly $504 in electricity alone, before purchase price or repairs.
By the numbers
The Aeocky RHEA-RCS32(Y)-N4-3 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 $63/yr, here is what the Aeocky RHEA-RCS32(Y)-N4-3 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-RCS32(Y)-N4-3 costs about $630. That is roughly $10 less than the class median, which would run closer to $640 over the same ten years.
How the Aeocky RHEA-RCS32(Y)-N4-3 compares
The dehumidifier class we track runs from $19 to $521 a year. At $63/yr, it runs about $1 a year cheaper than the class median of $64, and it is about $44 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 32 pints/day, the Aeocky RHEA-RCS32(Y)-N4-3 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, putting it squarely in the middle of the class on the size lever that drives most of the cost. The IEF of 2.09 on this model, above the class median of 2.01, measures integrated energy factor; it is the number to compare directly against another model's IEF if capacity is similar.
- 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-RCS32(Y)-N4-3 cheap to run?
It is about average. At $63 a year it ranks #246 of 519 dehumidifier models we track, close to the middle of its class on running cost.
How much does the Aeocky RHEA-RCS32(Y)-N4-3 cost per month?
Roughly $5.24/mo, spreading the $63/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 339 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $63 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Aeocky RHEA-RCS32(Y)-N4-3 for its size?
48th percentile once size is factored in, a fairly typical result for the class.
