Model
Vissani VAD50S1AWTS
Rank #386 means 385 of the 519 dehumidifier models we track cost less to run each year; the 84th efficiency percentile means it uses less energy for its size than 84% of those models.
What does the Vissani VAD50S1AWTS cost to run per year?
The Vissani VAD50S1AWTS costs about $95 a year to run, more than most of the 519 dehumidifier models we track; it ranks #386. Its size-adjusted efficiency percentile of 84 sits well above the class median, a clearly above-average efficiency result. 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 VAD50PS1BWTS at $95/yr runs a little cheaper and the Vissani VAD50S1BWTS at $95/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 VAD50S1AWTS's $95/yr adds up to roughly $760 in electricity alone, before purchase price or repairs.
Also sold as: Black+Decker BDM50WCDA.
By the numbers
The Vissani VAD50S1AWTS 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 $95/yr, here is what the Vissani VAD50S1AWTS 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 VAD50S1AWTS costs about $950. That is roughly $310 more than the class median, which would run closer to $640 over the same ten years.
How the Vissani VAD50S1AWTS compares
The dehumidifier class we track runs from $19 to $521 a year. At $95/yr, it runs about $31 a year above the class median of $64, and it is about $76 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 49.95 pints/day, the Vissani VAD50S1AWTS is a large dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, among dehumidifier models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal. Its IEF of 2.01, above the class median of 2.01, reflects integrated energy factor: a higher figure means it wrings more useful work out of every kilowatt-hour, so it is the efficiency lever to weigh against raw size.
- 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 Vissani VAD50S1AWTS cheap to run?
Its $95/yr running cost, rank #386 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 Vissani VAD50S1AWTS cost per month?
About $7.92 a month, which is the $95 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: 512 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $95 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Vissani VAD50S1AWTS for its size?
84th 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.
