Model
Megalight PD-HPC750-WT
Rank #337 means 336 of the 519 dehumidifier models we track cost less to run each year; the 96th efficiency percentile means it uses less energy for its size than 96% of those models.
What does the Megalight PD-HPC750-WT cost to run per year?
At roughly $88 a year to run, ranking #337 of 519, the Megalight PD-HPC750-WT costs more than the typical dehumidifier model we track. Its size-adjusted efficiency percentile of 96 means the low running cost is not just a function of size; almost nothing in the class beats it on efficiency once capacity is accounted for. At a IEF of 2.2, 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 Waykar CTH150PD at $87/yr runs a little cheaper and the Yoau, Shinco, Uhome YDZ-50P/S6 at $88/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 Megalight PD-HPC750-WT's $88/yr adds up to roughly $704 in electricity alone, before purchase price or repairs.
By the numbers
The Megalight PD-HPC750-WT 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 $88/yr, here is what the Megalight PD-HPC750-WT adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Megalight PD-HPC750-WT costs about $880. That is roughly $240 more than the class median, which would run closer to $640 over the same ten years.
How the Megalight PD-HPC750-WT compares
The dehumidifier class we track runs from $19 to $521 a year. At $88/yr, it runs about $24 a year above the class median of $64, and it is about $69 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 49.43 pints/day, the Megalight PD-HPC750-WT 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. Beyond size, its IEF of 2.2, 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 Megalight PD-HPC750-WT cheap to run?
Its $88/yr running cost, rank #337 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 Megalight PD-HPC750-WT cost per month?
About $7.3 a month, which is the $88 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: 472 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $88 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Megalight PD-HPC750-WT for its size?
96th 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.
