Model
Lg DLHC8402*
Rank #45 means 44 of the 615 clothes dryer models we track cost less to run each year; the 96th efficiency percentile means it uses less energy for its size than 96% of those models.
What does the Lg DLHC8402* cost to run per year?
The Lg DLHC8402* holds rank #45 of 615 on running cost, at about $48 a year, a genuinely cheap result for the class. Few clothes dryer models we track are more efficient for their size than this one; its size-adjusted efficiency percentile of 96 is near the top of the class. At a CEF of 9.3, 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 DLHC3602* at $48/yr runs a little cheaper and the Asko T411HS.W.U at $49/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 Lg DLHC8402*'s $48/yr adds up to roughly $624 in electricity alone, before purchase price or repairs.
By the numbers
The Lg DLHC8402* 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 $48/yr, here is what the Lg DLHC8402* adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Lg DLHC8402* costs about $480. That is roughly $650 less than the class median, which would run closer to $1130 over the same ten years.
How the Lg DLHC8402* compares
The clothes dryer class we track runs from $23 to $128 a year. At $48/yr, it runs about $65 a year cheaper than the class median of $113, and it is about $25 a year more than the cheapest clothes dryer to run at $23.
What drives its running cost
At 7.3 cu ft, the Lg DLHC8402* 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. Beyond size, its CEF of 9.3, 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 Lg DLHC8402* cheap to run?
Yes. Its $48/yr running cost puts it at rank #45 of 615, below what most clothes dryer models we track cost to run.
How much does the Lg DLHC8402* cost per month?
About $3.97 a month, which is the $48 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: 257 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $48 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Lg DLHC8402* for its size?
96th 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.
