Model
Vissani VAD25S1BWTS
Rank #162 means 161 of the 519 dehumidifier models we track cost less to run each year; the 62nd efficiency percentile means it uses less energy for its size than 62% of those models.
What does the Vissani VAD25S1BWTS cost to run per year?
At $53 a year to run, the Vissani VAD25S1BWTS runs cheaper than most models in its class, ranking #162 of 519 dehumidifier models we track. Its 62th size-adjusted efficiency percentile is a step ahead of the class median, though not among the very top results. 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 Vissani VAD25S1AWTS at $53/yr runs a little cheaper and the Waykar CTH80D at $53/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 Vissani VAD25S1BWTS's $53/yr adds up to roughly $424 in electricity alone, before purchase price or repairs.
Also sold as: Midea MDUDA-25AEN8-BB0F.
By the numbers
The Vissani VAD25S1BWTS 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 $53/yr, here is what the Vissani VAD25S1BWTS adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Vissani VAD25S1BWTS costs about $530. That is roughly $110 less than the class median, which would run closer to $640 over the same ten years.
How the Vissani VAD25S1BWTS compares
The dehumidifier class we track runs from $19 to $521 a year. At $53/yr, it runs about $11 a year cheaper than the class median of $64, and it is about $34 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 26.87 pints/day, the Vissani VAD25S1BWTS 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 Vissani VAD25S1BWTS cheap to run?
Yes, relatively. At $53 a year it ranks #162 of 519 dehumidifier models we track, in the cheaper part of its class to run.
How much does the Vissani VAD25S1BWTS cost per month?
Roughly $4.38/mo, spreading the $53/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 283 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $53 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Vissani VAD25S1BWTS for its size?
62nd percentile once size is factored in, a fairly typical result for the class.
