Model
Lg DT351BWR0
Rank #284 means 283 of the 519 dehumidifier models we track cost less to run each year; the 59th efficiency percentile means it uses less energy for its size than 59% of those models.
What does the Lg DT351BWR0 cost to run per year?
Do the math and the Lg DT351BWR0's $69/yr puts it at rank #284 of 519, right around the class average. Adjusted for size, it is more efficient than 59% of dehumidifier models we track, a middling result. The IEF figure of 2.01 on this model captures integrated energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Waykar CHWA120A at $68/yr runs a little cheaper and the Fehom JD025L-120 at $70/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 DT351BWR0's $69/yr adds up to roughly $552 in electricity alone, before purchase price or repairs.
By the numbers
The Lg DT351BWR0 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 $69/yr, here is what the Lg DT351BWR0 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 DT351BWR0 costs about $690. That is roughly $50 more than the class median, which would run closer to $640 over the same ten years.
How the Lg DT351BWR0 compares
The dehumidifier class we track runs from $19 to $521 a year. At $69/yr, it runs about $5 a year above the class median of $64, and it is about $50 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 35.3 pints/day, the Lg DT351BWR0 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, putting it squarely in the middle of the class on the size lever that drives most of the cost. The IEF of 2.01 on this model, above the class median of 2.01, measures integrated energy factor; it is the number to compare directly against another model's IEF if capacity is similar.
- Integrated Energy Factor (IEF). Two dehumidifiers rated for the same pints per day can carry very different IEF figures, and IEF is what actually separates their running costs.
- Water removal capacity (pints/day). Pints-per-day rating scales with the space it is built for, and that rating is the first driver of how much power the compressor needs.
- Humidistat accuracy. How tightly a humidistat holds its target humidity determines how much of the day the compressor actually runs, on top of the unit's rated capacity and IEF.
Common questions
Is the Lg DT351BWR0 cheap to run?
It is about average. At $69 a year it ranks #284 of 519 dehumidifier models we track, close to the middle of its class on running cost.
How much does the Lg DT351BWR0 cost per month?
Roughly $5.75/mo, spreading the $69/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 372 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $69 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg DT351BWR0 for its size?
59th percentile once size is factored in, a fairly typical result for the class.
