Model
Coolworks TDUDP-22AEN8-BA7
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 Coolworks TDUDP-22AEN8-BA7 cost to run per year?
The Coolworks TDUDP-22AEN8-BA7 costs about $52 a year to run, which beats most of the 519 dehumidifier models we track; it ranks #136. Capacity-normalized, it ranks ahead of just 7% of dehumidifier models we track, a clearly below-average result. At a IEF of 1.7, 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 Omni Max OD22MTWBA1RCM at $52/yr runs a little cheaper and the Perfect Aire 3PFD22 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 Coolworks TDUDP-22AEN8-BA7'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 Coolworks TDUDP-22AEN8-BA7 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 Coolworks TDUDP-22AEN8-BA7 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Coolworks TDUDP-22AEN8-BA7 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 Coolworks TDUDP-22AEN8-BA7 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 Coolworks TDUDP-22AEN8-BA7 is a small dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture. Beyond size, its IEF of 1.7, 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 Coolworks TDUDP-22AEN8-BA7 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 Coolworks TDUDP-22AEN8-BA7 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 Coolworks TDUDP-22AEN8-BA7 for its size?
7th percentile once size is factored in, a fairly typical result for the class.
