Model
Tcl T50DC3S
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 Tcl T50DC3S cost to run per year?
The Tcl T50DC3S is a relatively costly runner for its class: about $96 a year, rank #399 of 519. Its 76th size-adjusted efficiency percentile is a step ahead of the class median, though not among the very top results. Its IEF of 2.01 reflects integrated energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Tcl H50D46W at $96/yr runs a little cheaper and the Tcl T50DC3SP 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 Tcl T50DC3S'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 Tcl T50DC3S 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 Tcl T50DC3S adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Tcl T50DC3S 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 Tcl T50DC3S 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 Tcl T50DC3S is a large dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, among dehumidifier models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal. 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 Tcl T50DC3S cheap to run?
Not especially. At $96 a year it ranks #399 of 519 dehumidifier models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Tcl T50DC3S cost per month?
Roughly $7.98/mo, spreading the $96/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 516 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $96 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Tcl T50DC3S 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.
