Model
Keystone KSTAD354G
Rank #325 means 324 of the 519 dehumidifier models we track cost less to run each year; the 49th efficiency percentile means it uses less energy for its size than 49% of those models.
What does the Keystone KSTAD354G cost to run per year?
Among the 519 dehumidifier models we track, the Keystone KSTAD354G's $72/yr running cost ranks it #325, in the above-average-cost group. Efficiency-wise, once size is accounted for, it sits right around the class median, ahead of 49% of the models we track. The IEF figure of 2.01 on this model captures integrated energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Black+Decker BDM36WCDA at $71/yr runs a little cheaper and the Amazon Basics B0GR2L3R49 at $72/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 Keystone KSTAD354G's $72/yr adds up to roughly $576 in electricity alone, before purchase price or repairs.
Also sold as: Amazon Basics B0GR2L3R49.
By the numbers
The Keystone KSTAD354G 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 $72/yr, here is what the Keystone KSTAD354G adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Keystone KSTAD354G costs about $720. That is roughly $80 more than the class median, which would run closer to $640 over the same ten years.
How the Keystone KSTAD354G compares
The dehumidifier class we track runs from $19 to $521 a year. At $72/yr, it runs about $8 a year above the class median of $64, and it is about $53 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 36.71 pints/day, the Keystone KSTAD354G 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). 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 Keystone KSTAD354G cheap to run?
Its $72/yr running cost, rank #325 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 Keystone KSTAD354G cost per month?
About $6 a month, which is the $72 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: 388 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $72 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Keystone KSTAD354G for its size?
49th 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.
