Model
Quilo QLDAD50PWK
Rank #358 means 357 of the 519 dehumidifier models we track cost less to run each year; the 90th efficiency percentile means it uses less energy for its size than 90% of those models.
What does the Quilo QLDAD50PWK cost to run per year?
At $94 a year to run, the Quilo QLDAD50PWK runs more expensively than most models in its class, ranking #358 of 519 dehumidifier models we track. Efficiency-wise, once capacity is accounted for, it beats 90% of the class, a solidly strong result rather than a size-driven fluke. 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 Zafro D026W-50Pt3M at $94/yr runs a little cheaper and the Quilo QLDAD50WK at $94/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 Quilo QLDAD50PWK's $94/yr adds up to roughly $752 in electricity alone, before purchase price or repairs.
Also sold as: Aux ADT50V1.
By the numbers
The Quilo QLDAD50PWK 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 $94/yr, here is what the Quilo QLDAD50PWK adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Quilo QLDAD50PWK costs about $940. That is roughly $300 more than the class median, which would run closer to $640 over the same ten years.
How the Quilo QLDAD50PWK compares
The dehumidifier class we track runs from $19 to $521 a year. At $94/yr, it runs about $30 a year above the class median of $64, and it is about $75 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 49.67 pints/day, the Quilo QLDAD50PWK is a large dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, size is usually the single biggest lever behind a running-cost figure, and at this end of the range there is more capacity to service, which tends to push the number up. Beyond size, its IEF of 2.01, above 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). 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 Quilo QLDAD50PWK cheap to run?
Not especially. At $94 a year it ranks #358 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 Quilo QLDAD50PWK cost per month?
Roughly $7.8/mo, spreading the $94/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 504 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $94 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Quilo QLDAD50PWK for its size?
90th percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
