Model
Wellsle YDL12P
Rank #328 means 327 of the 519 dehumidifier models we track cost less to run each year; the 0th efficiency percentile means it uses less energy for its size than 0% of those models.
What does the Wellsle YDL12P cost to run per year?
At about $77 a year, the Wellsle YDL12P costs more to run than most dehumidifier models we track, rank #328 of 519. Efficiency-wise, once size is accounted for, almost the entire class outperforms it, at just the 0th percentile. The IEF figure of 1.85 on this model captures integrated energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Midea MDUDP-35AEN8-BB0 at $72/yr runs a little cheaper and the Santa Fe 4047100 at $78/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 Wellsle YDL12P's $77/yr adds up to roughly $616 in electricity alone, before purchase price or repairs.
By the numbers
The Wellsle YDL12P 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 $77/yr, here is what the Wellsle YDL12P adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Wellsle YDL12P costs about $770. That is roughly $130 more than the class median, which would run closer to $640 over the same ten years.
How the Wellsle YDL12P compares
The dehumidifier class we track runs from $19 to $521 a year. At $77/yr, it runs about $13 a year above the class median of $64, and it is about $58 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 12 pints/day, the Wellsle YDL12P is a small dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, and smaller dehumidifier models generally cost less to run for the same job, all else being equal. Beyond size, its IEF of 1.85, 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 Wellsle YDL12P cheap to run?
Its $77/yr running cost, rank #328 of 519, is above what most dehumidifier models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Wellsle YDL12P cost per month?
About $6.39 a month, which is the $77 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: 413 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $77 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Wellsle YDL12P for its size?
0th 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.
