Model
Deciuu LIBRA-RCS25(Y)-N4-3(B)-25
Rank #168 means 167 of the 519 dehumidifier models we track cost less to run each year; the 36th efficiency percentile means it uses less energy for its size than 36% of those models.
What does the Deciuu LIBRA-RCS25(Y)-N4-3(B)-25 cost to run per year?
Ranking #168 of 519, the Deciuu LIBRA-RCS25(Y)-N4-3(B)-25 is in the cheaper half of its class to run, at about $53 a year. Normalized for capacity, it beats only 36% of dehumidifier models we track, a below-average efficiency result. At a IEF of 1.88, 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 Waykar CTH80D at $53/yr runs a little cheaper and the Aeroid TDP070-G100 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 Deciuu LIBRA-RCS25(Y)-N4-3(B)-25's $53/yr adds up to roughly $424 in electricity alone, before purchase price or repairs.
By the numbers
The Deciuu LIBRA-RCS25(Y)-N4-3(B)-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 Deciuu LIBRA-RCS25(Y)-N4-3(B)-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 Deciuu LIBRA-RCS25(Y)-N4-3(B)-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 Deciuu LIBRA-RCS25(Y)-N4-3(B)-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 24.72 pints/day, the Deciuu LIBRA-RCS25(Y)-N4-3(B)-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, putting it squarely in the middle of the class on the size lever that drives most of the cost. The IEF of 1.88 on this model, below 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 Deciuu LIBRA-RCS25(Y)-N4-3(B)-25 cheap to run?
Yes, relatively. At $53 a year it ranks #168 of 519 dehumidifier models we track, in the cheaper part of its class to run.
How much does the Deciuu LIBRA-RCS25(Y)-N4-3(B)-25 cost per month?
Roughly $4.39/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 284 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 Deciuu LIBRA-RCS25(Y)-N4-3(B)-25 for its size?
36th percentile once size is factored in, a fairly typical result for the class.
