Model
Gasbye DryPrime-35-BP
Rank #292 means 291 of the 519 dehumidifier models we track cost less to run each year; the 79th efficiency percentile means it uses less energy for its size than 79% of those models.
What does the Gasbye DryPrime-35-BP cost to run per year?
Ranking #292 of 519, the Gasbye DryPrime-35-BP runs at roughly $70 a year, neither the cheapest nor the priciest in its class. Adjusted for size, it is more efficient than 79% of dehumidifier models we track, a solidly above-average result. At a IEF of 2.01, 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 MDUDMB-35AEN8-BB0F at $70/yr runs a little cheaper and the Abestorm Guardian SN55S 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 Gasbye DryPrime-35-BP's $70/yr adds up to roughly $560 in electricity alone, before purchase price or repairs.
Also sold as: Friedrich D35C1A.
By the numbers
The Gasbye DryPrime-35-BP 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 Gasbye DryPrime-35-BP adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Gasbye DryPrime-35-BP 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 Gasbye DryPrime-35-BP 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 36.53 pints/day, the Gasbye DryPrime-35-BP 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 2.01, 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). 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 Gasbye DryPrime-35-BP cheap to run?
It is about average. At $70 a year it ranks #292 of 519 dehumidifier models we track, close to the middle of its class on running cost.
How much does the Gasbye DryPrime-35-BP cost per month?
Roughly $5.85/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 378 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 Gasbye DryPrime-35-BP for its size?
79th percentile once size is factored in, a fairly typical result for the class.
