Model
Wellsle YDL24P
Rank #509 means 508 of the 519 dehumidifier models we track cost less to run each year; the 1st efficiency percentile means it uses less energy for its size than 1% of those models.
What does the Wellsle YDL24P cost to run per year?
Almost nothing we track in this class costs more to run than the Wellsle YDL24P: about $147 a year, rank #509 of 519. Normalized for capacity, it beats only 1% of dehumidifier models we track, the weakest tier this efficiency ranking produces. At a IEF of 2.01, 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 Costway ES10429US-WH at $145/yr runs a little cheaper and the Aprilaire E100 at $152/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 YDL24P's $147/yr adds up to roughly $1176 in electricity alone, before purchase price or repairs.
By the numbers
The Wellsle YDL24P 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 $147/yr, here is what the Wellsle YDL24P 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 YDL24P costs about $1470. That is roughly $830 more than the class median, which would run closer to $640 over the same ten years.
How the Wellsle YDL24P compares
The dehumidifier class we track runs from $19 to $521 a year. At $147/yr, it runs about $83 a year above the class median of $64, and it is about $128 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 25 pints/day, the Wellsle YDL24P 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. 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 Wellsle YDL24P cheap to run?
Not especially. At $147 a year it ranks #509 of 519 dehumidifier models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Wellsle YDL24P cost per month?
Roughly $12.23/mo, spreading the $147/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 791 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $147 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Wellsle YDL24P for its size?
1st 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.
