Model
Gianna AS-CSJ72XK-2WT-OL
Rank #3 means 2 of the 519 dehumidifier models we track cost less to run each year; the 35th efficiency percentile means it uses less energy for its size than 35% of those models.
What does the Gianna AS-CSJ72XK-2WT-OL cost to run per year?
Almost nothing we track in this class costs less to run than the Gianna AS-CSJ72XK-2WT-OL: about $19 a year, rank #3 of 519. Adjusted for size, it is only more efficient than 35% of dehumidifier models we track, so part of its running cost comes from its capacity rather than efficiency alone. At a IEF of 1.93, 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 Edx AS-CSJ72XK-2WT-OL at $19/yr runs a little cheaper and the Iululu AS-CSJ72XK-2WT-OL at $19/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 Gianna AS-CSJ72XK-2WT-OL's $19/yr adds up to roughly $152 in electricity alone, before purchase price or repairs. At rank #3 of 519, it is one of the single cheapest dehumidifier models we track to run, in the top one percent on cost.
Also sold as: Concetta AS-CSJ72XK-2WT-OL.
By the numbers
The Gianna AS-CSJ72XK-2WT-OL 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 $19/yr, here is what the Gianna AS-CSJ72XK-2WT-OL adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Gianna AS-CSJ72XK-2WT-OL costs about $190. That is roughly $450 less than the class median, which would run closer to $640 over the same ten years.
How the Gianna AS-CSJ72XK-2WT-OL compares
The dehumidifier class we track runs from $19 to $521 a year. At $19/yr, it runs about $45 a year cheaper than the class median of $64, and it is the cheapest dehumidifier to run in the class among the models we track.
What drives its running cost
At 9 pints/day, the Gianna AS-CSJ72XK-2WT-OL is a small dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture. The IEF of 1.93 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 Gianna AS-CSJ72XK-2WT-OL cheap to run?
Yes, relatively. At $19 a year it ranks #3 of 519 dehumidifier models we track, in the cheaper part of its class to run.
How much does the Gianna AS-CSJ72XK-2WT-OL cost per month?
Roughly $1.62/mo, spreading the $19/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 105 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $19 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Gianna AS-CSJ72XK-2WT-OL for its size?
35th percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
