Model
Waykar PD160B-PRO
Rank #35 means 34 of the 519 dehumidifier models we track cost less to run each year; the 3rd efficiency percentile means it uses less energy for its size than 3% of those models.
What does the Waykar PD160B-PRO cost to run per year?
The Waykar PD160B-PRO runs for about $27 a year, landing it near the bottom of the cost table at rank #35 of 519 dehumidifier models we track. Its size-adjusted efficiency percentile of 3 means its running cost, whatever it is, owes almost nothing to efficiency and almost everything to capacity. The IEF figure of 1.91 on this model captures integrated energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Asahwo PD22SA at $26/yr runs a little cheaper and the Waykar PD160B-PRO-A at $27/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 Waykar PD160B-PRO's $27/yr adds up to roughly $216 in electricity alone, before purchase price or repairs.
Also sold as: Waykar PD160B-PRO-A, Waykar PD160B-PRO-B, Waykar PD160B-PRO-G.
By the numbers
The Waykar PD160B-PRO 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 $27/yr, here is what the Waykar PD160B-PRO adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Waykar PD160B-PRO costs about $270. That is roughly $370 less than the class median, which would run closer to $640 over the same ten years.
How the Waykar PD160B-PRO compares
The dehumidifier class we track runs from $19 to $521 a year. At $27/yr, it runs about $37 a year cheaper than the class median of $64, and it is about $8 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 10.16 pints/day, the Waykar PD160B-PRO 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. Its IEF of 1.91, 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 Waykar PD160B-PRO cheap to run?
Yes. Its $27/yr running cost puts it at rank #35 of 519, below what most dehumidifier models we track cost to run.
How much does the Waykar PD160B-PRO cost per month?
About $2.23 a month, which is the $27 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: 144 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $27 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Waykar PD160B-PRO for its size?
3rd 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.
