Model
Deye DYD-P30
Rank #78 means 77 of the 519 dehumidifier models we track cost less to run each year; the 88th efficiency percentile means it uses less energy for its size than 88% of those models.
What does the Deye DYD-P30 cost to run per year?
Rank #78 of 519 puts the Deye DYD-P30 among the cheapest dehumidifier models we track to keep running, at roughly $48 a year. Few dehumidifier models we track beat it on size-adjusted efficiency; it edges out 88% of the class once capacity is normalized. At a IEF of 2.03, 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 Midea MDUDMA-20AEN8-BA7 at $46/yr runs a little cheaper and the Aeronova ADC018 at $48/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 Deye DYD-P30's $48/yr adds up to roughly $384 in electricity alone, before purchase price or repairs.
By the numbers
The Deye DYD-P30 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 $48/yr, here is what the Deye DYD-P30 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Deye DYD-P30 costs about $480. That is roughly $160 less than the class median, which would run closer to $640 over the same ten years.
How the Deye DYD-P30 compares
The dehumidifier class we track runs from $19 to $521 a year. At $48/yr, it runs about $16 a year cheaper than the class median of $64, and it is about $29 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 25 pints/day, the Deye DYD-P30 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. Its IEF of 2.03, 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). 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 Deye DYD-P30 cheap to run?
Yes. Its $48/yr running cost puts it at rank #78 of 519, below what most dehumidifier models we track cost to run.
How much does the Deye DYD-P30 cost per month?
About $3.96 a month, which is the $48 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: 256 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $48 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Deye DYD-P30 for its size?
88th 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.
