Model
Danby DDR020BJ2WDB
Rank #136 means 135 of the 519 dehumidifier models we track cost less to run each year; the 7th efficiency percentile means it uses less energy for its size than 7% of those models.
What does the Danby DDR020BJ2WDB cost to run per year?
Ranking #136 of 519, the Danby DDR020BJ2WDB is in the cheaper half of its class to run, at about $52 a year. Normalized for capacity, it beats only 7% of dehumidifier models we track, one of the weaker efficiency results we track for the class. At a IEF of 1.7, 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 Keystone KSTAD224F at $52/yr runs a little cheaper and the Midea MAD22C1AWS at $52/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 Danby DDR020BJ2WDB's $52/yr adds up to roughly $416 in electricity alone, before purchase price or repairs.
Also sold as: Comfort Aire BHD-22B.
By the numbers
The Danby DDR020BJ2WDB 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 $52/yr, here is what the Danby DDR020BJ2WDB adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Danby DDR020BJ2WDB costs about $520. That is roughly $120 less than the class median, which would run closer to $640 over the same ten years.
How the Danby DDR020BJ2WDB compares
The dehumidifier class we track runs from $19 to $521 a year. At $52/yr, it runs about $12 a year cheaper than the class median of $64, and it is about $33 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 22.31 pints/day, the Danby DDR020BJ2WDB is a small dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is. The IEF of 1.7 on this model, below the class median of 2.01, measures integrated energy factor; it is the number to compare directly against another model's IEF if capacity is similar.
- 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 Danby DDR020BJ2WDB cheap to run?
Yes, relatively. At $52 a year it ranks #136 of 519 dehumidifier models we track, in the cheaper part of its class to run.
How much does the Danby DDR020BJ2WDB cost per month?
Roughly $4.3/mo, spreading the $52/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 278 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $52 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Danby DDR020BJ2WDB for its size?
7th percentile once size is factored in, a fairly typical result for the class.
