Model
Miele TXI680WP
Rank #13 means 12 of the 615 clothes dryer models we track cost less to run each year; the 98th efficiency percentile means it uses less energy for its size than 98% of those models.
What does the Miele TXI680WP cost to run per year?
Rank #13 of 615 puts the Miele TXI680WP at the very top of the cheapest-to-run leaderboard for its class, at roughly $25 a year. Its size-adjusted efficiency percentile of 98 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. The CEF figure of 6.37 on this model captures combined energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Miele TWI680WP at $25/yr runs a little cheaper and the Miele TWD360WP at $25/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 Miele TXI680WP's $25/yr adds up to roughly $325 in electricity alone, before purchase price or repairs.
Also sold as: Miele TWD160WP.
By the numbers
The Miele TXI680WP 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 $25/yr, here is what the Miele TXI680WP adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Miele TXI680WP costs about $250. That is roughly $880 less than the class median, which would run closer to $1130 over the same ten years.
How the Miele TXI680WP compares
The clothes dryer class we track runs from $23 to $128 a year. At $25/yr, it runs about $88 a year cheaper than the class median of $113, and it is about $2 a year more than the cheapest clothes dryer to run at $23.
What drives its running cost
At 4.1 cu ft, the Miele TXI680WP 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. The CEF of 6.37 on this model, above the class median of 3.93, measures combined energy factor; it is the number to compare directly against another model's CEF if capacity is similar.
- 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 Miele TXI680WP cheap to run?
Yes. Its $25/yr running cost puts it at rank #13 of 615, below what most clothes dryer models we track cost to run.
How much does the Miele TXI680WP cost per month?
About $2.06 a month, which is the $25 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: 133 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $25 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Miele TXI680WP for its size?
98th 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.
