Model
Hisense OSD3526
Rank #272 means 271 of the 519 dehumidifier models we track cost less to run each year; the 81st efficiency percentile means it uses less energy for its size than 81% of those models.
What does the Hisense OSD3526 cost to run per year?
The Hisense OSD3526 costs about $67 a year to run, a middle-of-the-pack figure at rank #272 of 519. Efficiency-wise, once capacity is accounted for, it beats 81% 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 Hisense HD3526 at $67/yr runs a little cheaper and the Bosch Dry 4000 at $68/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 Hisense OSD3526's $67/yr adds up to roughly $536 in electricity alone, before purchase price or repairs.

By the numbers
The Hisense OSD3526 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 $67/yr, here is what the Hisense OSD3526 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Hisense OSD3526 costs about $670. That is roughly $30 more than the class median, which would run closer to $640 over the same ten years.
How the Hisense OSD3526 compares
The dehumidifier class we track runs from $19 to $521 a year. At $67/yr, it runs about $3 a year above the class median of $64, and it is about $48 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 35.32 pints/day, the Hisense OSD3526 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. 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 Hisense OSD3526 cheap to run?
It is about average. At $67 a year it ranks #272 of 519 dehumidifier models we track, close to the middle of its class on running cost.
How much does the Hisense OSD3526 cost per month?
Roughly $5.61/mo, spreading the $67/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 363 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $67 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Hisense OSD3526 for its size?
81st percentile once size is factored in, a fairly typical result for the class.
