Asko T3HW.U
Rank #16 means 15 of the 615 clothes dryer models we track cost less to run each year; the 97th efficiency percentile means it uses less energy for its size than 97% of those models.
What does the Asko T3HW.U cost to run per year?
Rank #16 of 615 puts the Asko T3HW.U at the very top of the cheapest-to-run leaderboard for its class, at roughly $26 a year. Few clothes dryer models we track are more efficient for their size than this one; its size-adjusted efficiency percentile of 97 is near the top of the class. At a CEF of 6, its combined energy factor is the single figure that best explains how it earns its running-cost number.
Immediately around it on the leaderboard, the Lg WKHC152H*A at $25/yr runs a little cheaper and the Samsung DV22N685*H* at $27/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 Asko T3HW.U's $26/yr adds up to roughly $338 in electricity alone, before purchase price or repairs.
By the numbers
The Asko T3HW.U 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 $26/yr, here is what the Asko T3HW.U adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Asko T3HW.U costs about $260. That is roughly $870 less than the class median, which would run closer to $1130 over the same ten years.
How the Asko T3HW.U compares
The clothes dryer class we track runs from $23 to $128 a year. At $26/yr, it runs about $87 a year cheaper than the class median of $113, and it is about $3 a year more than the cheapest clothes dryer to run at $23.
What drives its running cost
At 4.2 cu ft, the Asko T3HW.U 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, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture. Its CEF of 6, above the class median of 3.93, reflects combined 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.
- 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 Asko T3HW.U cheap to run?
Yes. Its $26/yr running cost puts it at rank #16 of 615, below what most clothes dryer models we track cost to run.
How much does the Asko T3HW.U cost per month?
About $2.2 a month, which is the $26 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: 142 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $26 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Asko T3HW.U for its size?
97th 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.
