What does the Aeocky RHEA PRO-RCS50(Y)-N4-3-25 cost to run per year?

Ranking #332 of 519, the Aeocky RHEA PRO-RCS50(Y)-N4-3-25 sits in the pricier half of its class to run, at about $80 a year. Normalized for capacity, it ranks ahead of 93% of dehumidifier models we track on efficiency, a genuinely strong showing. The IEF figure of 2.21 on this model captures integrated energy factor, the main efficiency lever ENERGY STAR tracks for this class.

Immediately around it on the leaderboard, the Pelonis PAD40C1AWTS at $80/yr runs a little cheaper and the Aeocky LEO PRO-RCS50(Y)-N4-3(B)-25 at $81/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 PRO-RCS50(Y)-N4-3-25's $80/yr adds up to roughly $640 in electricity alone, before purchase price or repairs.

What it costs you over time

Running cost is an every-year number, so it compounds. At $80/yr, here is what the Aeocky RHEA PRO-RCS50(Y)-N4-3-25 adds up to before purchase price, water, or repairs enter the math.

1 year$80
5 years$400
10 years$800

Left running for a decade at today's US average rate, the Aeocky RHEA PRO-RCS50(Y)-N4-3-25 costs about $800. That is roughly $160 more than the class median, which would run closer to $640 over the same ten years.

How the Aeocky RHEA PRO-RCS50(Y)-N4-3-25 compares

The dehumidifier class we track runs from $19 to $521 a year. At $80/yr, it runs about $16 a year above the class median of $64, and it is about $61 a year more than the cheapest dehumidifier to run at $19.

What drives its running cost

At 44.34 pints/day, the Aeocky RHEA PRO-RCS50(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, 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. Beyond size, its IEF of 2.21, above 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 PRO-RCS50(Y)-N4-3-25 cheap to run?

Not especially. At $80 a year it ranks #332 of 519 dehumidifier models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.

How much does the Aeocky RHEA PRO-RCS50(Y)-N4-3-25 cost per month?

Roughly $6.68/mo, spreading the $80/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 432 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $80 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.

How efficient is the Aeocky RHEA PRO-RCS50(Y)-N4-3-25 for its size?

93rd 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.
