Model
Lg WKHC152H*A
Rank #8 means 7 of the 615 clothes dryer models we track cost less to run each year; the 99th efficiency percentile means it uses less energy for its size than 99% of those models.
What does the Lg WKHC152H*A cost to run per year?
Rank #8 of 615 puts the Lg WKHC152H*A at the very top of the cheapest-to-run leaderboard for its class, at roughly $25 a year. Size-adjusted, this model beats 99% of clothes dryer models we track on efficiency, a standout even among the class's efficient models. At a CEF of 6.4, 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 Miele TXD160WP at $25/yr runs a little cheaper and the Asko T3HW.U at $26/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 WKHC152H*A's $25/yr adds up to roughly $325 in electricity alone, before purchase price or repairs.
Also sold as: Lg DLHC1455*.
By the numbers
The Lg WKHC152H*A 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 Lg WKHC152H*A 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 WKHC152H*A 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 Lg WKHC152H*A 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 4.2 cu ft, the Lg WKHC152H*A 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 6.4, 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 WKHC152H*A cheap to run?
Yes. Its $25/yr running cost puts it at rank #8 of 615, below what most clothes dryer models we track cost to run.
How much does the Lg WKHC152H*A 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 Lg WKHC152H*A for its size?
99th 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.
