Model
Senville SENDH-22AEN1X
Rank #136 means 135 of the 519 dehumidifier models we track cost less to run each year; the 7th efficiency percentile means it uses less energy for its size than 7% of those models.
What does the Senville SENDH-22AEN1X cost to run per year?
At about $52 a year, the Senville SENDH-22AEN1X undercuts most dehumidifier models we track on running cost, rank #136 of 519. Its size-adjusted efficiency percentile of 7 means the low running cost, where it exists, is driven almost entirely by capacity rather than efficiency. Its IEF of 1.7 reflects integrated energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Perfect Aire 3PFD22 at $52/yr runs a little cheaper and the Yoau, Shinco, Uhome SDZ1-80P at $52/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 Senville SENDH-22AEN1X's $52/yr adds up to roughly $416 in electricity alone, before purchase price or repairs.
Also sold as: Comfort Aire BHD-22B.
By the numbers
The Senville SENDH-22AEN1X 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 $52/yr, here is what the Senville SENDH-22AEN1X adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Senville SENDH-22AEN1X costs about $520. That is roughly $120 less than the class median, which would run closer to $640 over the same ten years.
How the Senville SENDH-22AEN1X compares
The dehumidifier class we track runs from $19 to $521 a year. At $52/yr, it runs about $12 a year cheaper than the class median of $64, and it is about $33 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 22.31 pints/day, the Senville SENDH-22AEN1X 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. Its IEF of 1.7, below 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). 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 Senville SENDH-22AEN1X cheap to run?
Yes. Its $52/yr running cost puts it at rank #136 of 519, below what most dehumidifier models we track cost to run.
How much does the Senville SENDH-22AEN1X cost per month?
About $4.3 a month, which is the $52 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: 278 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $52 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Senville SENDH-22AEN1X for its size?
7th percentile once size is factored in, a fairly typical result for the class.
