Model
Waykar CHWA150B
Rank #350 means 349 of the 519 dehumidifier models we track cost less to run each year; the 91st efficiency percentile means it uses less energy for its size than 91% of those models.
What does the Waykar CHWA150B cost to run per year?
Among the 519 dehumidifier models we track, the Waykar CHWA150B's $93/yr running cost ranks it #350, in the above-average-cost group. Its size-adjusted efficiency percentile of 91 sits well above the class median, a clearly above-average efficiency result. Its IEF of 2.01 reflects integrated energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Yoau; Shinco; Uhome YDZ1-50P/6P at $88/yr runs a little cheaper and the Waykar CHWA150E at $93/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 CHWA150B's $93/yr adds up to roughly $744 in electricity alone, before purchase price or repairs.
Also sold as: Waykar CHWA150E, Waykar CHWA150PB, Waykar CHWA150PE.
By the numbers
The Waykar CHWA150B 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 $93/yr, here is what the Waykar CHWA150B 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 CHWA150B costs about $930. That is roughly $290 more than the class median, which would run closer to $640 over the same ten years.
How the Waykar CHWA150B compares
The dehumidifier class we track runs from $19 to $521 a year. At $93/yr, it runs about $29 a year above the class median of $64, and it is about $74 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 49.52 pints/day, the Waykar CHWA150B is a large dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, and larger dehumidifier models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light. 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 Waykar CHWA150B cheap to run?
Its $93/yr running cost, rank #350 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 Waykar CHWA150B cost per month?
About $7.72 a month, which is the $93 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: 499 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $93 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Waykar CHWA150B for its size?
91st 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.
