Model
Waykar CTH150B
Rank #399 means 398 of the 519 dehumidifier models we track cost less to run each year; the 76th efficiency percentile means it uses less energy for its size than 76% of those models.
What does the Waykar CTH150B cost to run per year?
Among the 519 dehumidifier models we track, the Waykar CTH150B's $96/yr running cost ranks it #399, in the above-average-cost group. Its size-adjusted efficiency percentile of 76 is comfortably above the class median. 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 Waykar CTH150A at $96/yr runs a little cheaper and the Waykar CTH150PA at $96/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 CTH150B's $96/yr adds up to roughly $768 in electricity alone, before purchase price or repairs.
Also sold as: Duracomfort DH50PB.
By the numbers
The Waykar CTH150B 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 $96/yr, here is what the Waykar CTH150B 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 CTH150B costs about $960. That is roughly $320 more than the class median, which would run closer to $640 over the same ten years.
How the Waykar CTH150B compares
The dehumidifier class we track runs from $19 to $521 a year. At $96/yr, it runs about $32 a year above the class median of $64, and it is about $77 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 49.66 pints/day, the Waykar CTH150B 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 CTH150B cheap to run?
Its $96/yr running cost, rank #399 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 CTH150B cost per month?
About $7.98 a month, which is the $96 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: 516 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $96 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Waykar CTH150B for its size?
76th 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.
