Model
Dguam V2
Rank #56 means 55 of the 519 dehumidifier models we track cost less to run each year; the 22nd efficiency percentile means it uses less energy for its size than 22% of those models.
What does the Dguam V2 cost to run per year?
The Dguam V2 runs for about $34 a year, landing it near the bottom of the cost table at rank #56 of 519 dehumidifier models we track. Its size-adjusted efficiency percentile of 22 suggests its capacity is doing more work than its efficiency to keep the headline cost down. At a IEF of 1.8, 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 Jack&Rose DH02 at $34/yr runs a little cheaper and the Costway ES10328US-WH at $35/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 Dguam V2's $34/yr adds up to roughly $272 in electricity alone, before purchase price or repairs.
By the numbers
The Dguam V2 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 $34/yr, here is what the Dguam V2 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Dguam V2 costs about $340. That is roughly $300 less than the class median, which would run closer to $640 over the same ten years.
How the Dguam V2 compares
The dehumidifier class we track runs from $19 to $521 a year. At $34/yr, it runs about $30 a year cheaper than the class median of $64, and it is about $15 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 15.29 pints/day, the Dguam V2 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. Its IEF of 1.8, below 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 Dguam V2 cheap to run?
Yes. Its $34/yr running cost puts it at rank #56 of 519, below what most dehumidifier models we track cost to run.
How much does the Dguam V2 cost per month?
About $2.83 a month, which is the $34 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: 183 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $34 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Dguam V2 for its size?
22nd 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.
