Model
Truarctic TDFH4524HSW
Rank #101 means 100 of the 615 clothes dryer models we track cost less to run each year; the 3rd efficiency percentile means it uses less energy for its size than 3% of those models.
What does the Truarctic TDFH4524HSW cost to run per year?
Among the 615 clothes dryer models we track, the Truarctic TDFH4524HSW's $81/yr running cost ranks it #101, comfortably in the cheap-to-run group. Efficiency-wise, once size is accounted for, almost the entire class outperforms it, at just the 3th percentile. Its CEF of 5.5 reflects combined energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Premium Levella PHD450HW at $81/yr runs a little cheaper and the Truarctic TDFH4524HST at $81/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A clothes dryer typically stays in service for somewhere around 13 years; over that span, the Truarctic TDFH4524HSW's $81/yr adds up to roughly $1053 in electricity alone, before purchase price or repairs.
Also sold as: Hisense DH5S452BB.
By the numbers
The Truarctic TDFH4524HSW 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 $81/yr, here is what the Truarctic TDFH4524HSW adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Truarctic TDFH4524HSW costs about $810. That is roughly $320 less than the class median, which would run closer to $1130 over the same ten years.
How the Truarctic TDFH4524HSW compares
The clothes dryer class we track runs from $23 to $128 a year. At $81/yr, it runs about $32 a year cheaper than the class median of $113, and it is about $58 a year more than the cheapest clothes dryer to run at $23.
What drives its running cost
At 4.5 cu ft, the Truarctic TDFH4524HSW is a small clothes dryer for its class, which spans 3.8 to 9.2 cu ft with a median of 7.4 cu ft, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is. Beyond size, its CEF of 5.5, above the class median of 3.93, is the class's own efficiency yardstick, combined energy factor, and it is what separates two similarly sized models with different running costs.
- Heat source and Combined Energy Factor (CEF). Heat-pump dryers recycle heat instead of generating it fresh with a resistance coil, and typically use meaningfully less electricity per load than a conventional resistance dryer, at the cost of a longer cycle; CEF is the federal figure that captures this.
- Drum capacity. A larger drum can dry a bigger load per cycle, but it also usually needs more energy per cycle to heat the extra air volume.
Common questions
Is the Truarctic TDFH4524HSW cheap to run?
Yes. Its $81/yr running cost puts it at rank #101 of 615, below what most clothes dryer models we track cost to run.
How much does the Truarctic TDFH4524HSW cost per month?
About $6.73 a month, which is the $81 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: 435 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $81 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Truarctic TDFH4524HSW for its size?
3rd percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
