Model
Deciuu LIBRA-RCS32(Y)-N4-3(B)
Rank #238 means 237 of the 519 dehumidifier models we track cost less to run each year; the 73rd efficiency percentile means it uses less energy for its size than 73% of those models.
What does the Deciuu LIBRA-RCS32(Y)-N4-3(B) cost to run per year?
Do the math and the Deciuu LIBRA-RCS32(Y)-N4-3(B)'s $62/yr puts it at rank #238 of 519, right around the class average. Adjusted for size, it is more efficient than 73% of dehumidifier models we track, a solidly above-average result. Its IEF of 2.07 reflects integrated energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Rona DH2526RPB at $58/yr runs a little cheaper and the Deciuu LIBRA-RCS32(Y)-N4-3 at $62/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 Deciuu LIBRA-RCS32(Y)-N4-3(B)'s $62/yr adds up to roughly $496 in electricity alone, before purchase price or repairs.
By the numbers
The Deciuu LIBRA-RCS32(Y)-N4-3(B) 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 $62/yr, here is what the Deciuu LIBRA-RCS32(Y)-N4-3(B) adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Deciuu LIBRA-RCS32(Y)-N4-3(B) costs about $620. That is roughly $20 less than the class median, which would run closer to $640 over the same ten years.
How the Deciuu LIBRA-RCS32(Y)-N4-3(B) compares
The dehumidifier class we track runs from $19 to $521 a year. At $62/yr, it runs about $2 a year cheaper than the class median of $64, and it is about $43 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 32 pints/day, the Deciuu LIBRA-RCS32(Y)-N4-3(B) 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 2.07, above 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 Deciuu LIBRA-RCS32(Y)-N4-3(B) cheap to run?
It is about average. At $62 a year it ranks #238 of 519 dehumidifier models we track, close to the middle of its class on running cost.
How much does the Deciuu LIBRA-RCS32(Y)-N4-3(B) cost per month?
Roughly $5.15/mo, spreading the $62/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 333 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $62 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Deciuu LIBRA-RCS32(Y)-N4-3(B) for its size?
73rd percentile once size is factored in, a fairly typical result for the class.
