Model
Costway ES10328US-WH
Rank #57 means 56 of the 519 dehumidifier models we track cost less to run each year; the 14th efficiency percentile means it uses less energy for its size than 14% of those models.
What does the Costway ES10328US-WH cost to run per year?
Rank #57 of 519 puts the Costway ES10328US-WH among the cheapest dehumidifier models we track to keep running, at roughly $35 a year. Capacity-normalized, it ranks ahead of just 14% of dehumidifier models we track, a clearly below-average result. Its IEF of 1.75 reflects integrated energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Dguam V2 at $34/yr runs a little cheaper and the Glowells PD12A at $36/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 Costway ES10328US-WH's $35/yr adds up to roughly $280 in electricity alone, before purchase price or repairs.
By the numbers
The Costway ES10328US-WH 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 $35/yr, here is what the Costway ES10328US-WH adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Costway ES10328US-WH costs about $350. That is roughly $290 less than the class median, which would run closer to $640 over the same ten years.
How the Costway ES10328US-WH compares
The dehumidifier class we track runs from $19 to $521 a year. At $35/yr, it runs about $29 a year cheaper than the class median of $64, and it is about $16 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 15.5 pints/day, the Costway ES10328US-WH 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 1.75, 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 Costway ES10328US-WH cheap to run?
Yes. Its $35/yr running cost puts it at rank #57 of 519, below what most dehumidifier models we track cost to run.
How much does the Costway ES10328US-WH cost per month?
About $2.95 a month, which is the $35 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: 191 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $35 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Costway ES10328US-WH for its size?
14th percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
