Model
Sahauhy WTE120P-035P
Rank #285 means 284 of the 519 dehumidifier models we track cost less to run each year; the 67th efficiency percentile means it uses less energy for its size than 67% of those models.
What does the Sahauhy WTE120P-035P cost to run per year?
Ranking #285 of 519, the Sahauhy WTE120P-035P runs at roughly $70 a year, neither the cheapest nor the priciest in its class. Adjusted for size, it is more efficient than 67% of dehumidifier models we track, a solidly above-average result. 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 Sahauhy WTE120A-035T at $70/yr runs a little cheaper and the Waykar JD025CE-120 at $70/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 Sahauhy WTE120P-035P's $70/yr adds up to roughly $560 in electricity alone, before purchase price or repairs.
Also sold as: Fehom JD025L-120.
By the numbers
The Sahauhy WTE120P-035P 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 $70/yr, here is what the Sahauhy WTE120P-035P adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Sahauhy WTE120P-035P costs about $700. That is roughly $60 more than the class median, which would run closer to $640 over the same ten years.
How the Sahauhy WTE120P-035P compares
The dehumidifier class we track runs from $19 to $521 a year. At $70/yr, it runs about $6 a year above the class median of $64, and it is about $51 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 35.78 pints/day, the Sahauhy WTE120P-035P 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, putting it squarely in the middle of the class on the size lever that drives most of the cost. 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). Two dehumidifiers rated for the same pints per day can carry very different IEF figures, and IEF is what actually separates their running costs.
- Water removal capacity (pints/day). Pints-per-day rating scales with the space it is built for, and that rating is the first driver of how much power the compressor needs.
- Humidistat accuracy. How tightly a humidistat holds its target humidity determines how much of the day the compressor actually runs, on top of the unit's rated capacity and IEF.
Common questions
Is the Sahauhy WTE120P-035P cheap to run?
It is about average. At $70 a year it ranks #285 of 519 dehumidifier models we track, close to the middle of its class on running cost.
How much does the Sahauhy WTE120P-035P cost per month?
Roughly $5.8/mo, spreading the $70/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 375 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $70 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Sahauhy WTE120P-035P for its size?
67th percentile once size is factored in, a fairly typical result for the class.
