Model
Vissani VAD50S1BWTS
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 VAD50S1BWTS cost to run per year?
At $95 a year to run, the Vissani VAD50S1BWTS runs more expensively than most models in its class, ranking #386 of 519 dehumidifier models we track. Once capacity is factored in, it outperforms 84% of the dehumidifier models we track on efficiency, not just on headline running cost. 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 VAD50S1AWTS at $95/yr runs a little cheaper and the Vissani VADA50A5HWT 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 VAD50S1BWTS'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 VAD50S1BWTS 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 VAD50S1BWTS 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 VAD50S1BWTS 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 VAD50S1BWTS 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 VAD50S1BWTS 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). 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 VAD50S1BWTS cheap to run?
Not especially. At $95 a year it ranks #386 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 Vissani VAD50S1BWTS cost per month?
Roughly $7.92/mo, spreading the $95/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 512 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $95 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Vissani VAD50S1BWTS 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.
