Model
Airecoler Stellar SP10H
Rank #173 means 172 of the 519 dehumidifier models we track cost less to run each year; the 32nd efficiency percentile means it uses less energy for its size than 32% of those models.
What does the Airecoler Stellar SP10H cost to run per year?
At roughly $53 a year to run, ranking #173 of 519, the Airecoler Stellar SP10H costs less than the typical dehumidifier model we track. Size-adjusted, this model trails most of its class on efficiency, ahead of just 32% of dehumidifier models we track. Its IEF of 1.84 reflects integrated energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Airecoler Stellar SP10 at $53/yr runs a little cheaper and the Arecovas AR-DF006 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 Airecoler Stellar SP10H's $53/yr adds up to roughly $424 in electricity alone, before purchase price or repairs.
Also sold as: Airecoler Atlas T70.
By the numbers
The Airecoler Stellar SP10H 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 Airecoler Stellar SP10H adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Airecoler Stellar SP10H 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 Airecoler Stellar SP10H 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 24.43 pints/day, the Airecoler Stellar SP10H is a small dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is. Beyond size, its IEF of 1.84, 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). IEF measures liters of water removed per kilowatt-hour; a higher IEF means less energy per pint of moisture removed for a given capacity.
- Water removal capacity (pints/day). A dehumidifier rated to remove more pints per day is built for a larger space or a more humid room, and generally draws more power to do it.
- Humidistat accuracy. A unit with a more precise humidistat cycles the compressor off once the target humidity is reached, rather than running continuously.
Common questions
Is the Airecoler Stellar SP10H cheap to run?
Yes. Its $53/yr running cost puts it at rank #173 of 519, below what most dehumidifier models we track cost to run.
How much does the Airecoler Stellar SP10H cost per month?
About $4.41 a month, which is the $53 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 285 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $53 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Airecoler Stellar SP10H for its size?
32nd percentile once size is factored in, a fairly typical result for the class.
