Model
Kenmore 405.8227##
Rank #374 means 373 of the 615 clothes dryer models we track cost less to run each year; the 80th efficiency percentile means it uses less energy for its size than 80% of those models.
What does the Kenmore 405.8227## cost to run per year?
At about $113 a year, the Kenmore 405.8227## costs more to run than most clothes dryer models we track, rank #374 of 615. Few clothes dryer models we track beat it on size-adjusted efficiency; it edges out 80% of the class once capacity is normalized. At a CEF of 3.93, 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 Kenmore 405.8228## at $113/yr runs a little cheaper and the Aeg DHP240 at $113/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 Kenmore 405.8227##'s $113/yr adds up to roughly $1469 in electricity alone, before purchase price or repairs.
Also sold as: Crosley CFDMHE8105AW.
By the numbers
The Kenmore 405.8227## 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 $113/yr, here is what the Kenmore 405.8227## adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Kenmore 405.8227## costs about $1130. That is roughly $0 less than the class median, which would run closer to $1130 over the same ten years.
How the Kenmore 405.8227## compares
The clothes dryer class we track runs from $23 to $128 a year. At $113/yr, it sits right on the class median of $113, and it is about $90 a year more than the cheapest clothes dryer to run at $23.
What drives its running cost
At 8 cu ft, the Kenmore 405.8227## is a large clothes dryer for its class, which spans 3.8 to 9.2 cu ft with a median of 7.4 cu ft, and larger clothes dryer models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light. Beyond size, its CEF of 3.93, 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 Kenmore 405.8227## cheap to run?
Its $113/yr running cost, rank #374 of 615, is above what most clothes dryer models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Kenmore 405.8227## cost per month?
About $9.4 a month, which is the $113 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: 608 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $113 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Kenmore 405.8227## for its size?
80th 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.
