Model
Lg DT251BWR0
Rank #232 means 231 of the 519 dehumidifier models we track cost less to run each year; the 15th efficiency percentile means it uses less energy for its size than 15% of those models.
What does the Lg DT251BWR0 cost to run per year?
Among the 519 dehumidifier models we track, the Lg DT251BWR0's $57/yr running cost ranks it #232, close to dead center. Size-adjusted, this model ranks near the bottom of its class on efficiency, ahead of just 15% of dehumidifier models we track. The IEF figure of 1.71 on this model captures integrated energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Ge ADSE25W**# at $57/yr runs a little cheaper and the Hisense ADH25K26 at $58/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 Lg DT251BWR0's $57/yr adds up to roughly $456 in electricity alone, before purchase price or repairs.
By the numbers
The Lg DT251BWR0 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 $57/yr, here is what the Lg DT251BWR0 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Lg DT251BWR0 costs about $570. That is roughly $70 less than the class median, which would run closer to $640 over the same ten years.
How the Lg DT251BWR0 compares
The dehumidifier class we track runs from $19 to $521 a year. At $57/yr, it runs about $7 a year cheaper than the class median of $64, and it is about $38 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 24.99 pints/day, the Lg DT251BWR0 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, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class. Its IEF of 1.71, 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 Lg DT251BWR0 cheap to run?
Roughly, yes. Its $57/yr figure is close to the class median, ranking #232 of 519, neither a bargain nor a splurge on running cost.
How much does the Lg DT251BWR0 cost per month?
About $4.75 a month, which is the $57 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: 307 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $57 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Lg DT251BWR0 for its size?
15th percentile once size is factored in, a fairly typical result for the class.
