Model
Summit LDES248
Rank #79 means 78 of the 615 clothes dryer models we track cost less to run each year; the 72nd efficiency percentile means it uses less energy for its size than 72% of those models.
What does the Summit LDES248 cost to run per year?
Do the math and the Summit LDES248's $59/yr puts it at rank #79 of 615, one of the more affordable clothes dryer models we track to keep running. Adjusted for size, it is more efficient than 72% of clothes dryer models we track, a solidly above-average result. At a CEF of 2.68, 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 Marathon MVD420W at $59/yr runs a little cheaper and the Summit SLDC2404 at $59/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 Summit LDES248's $59/yr adds up to roughly $767 in electricity alone, before purchase price or repairs.
Also sold as: Aeg DC240.
By the numbers
The Summit LDES248 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 $59/yr, here is what the Summit LDES248 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Summit LDES248 costs about $590. That is roughly $540 less than the class median, which would run closer to $1130 over the same ten years.
How the Summit LDES248 compares
The clothes dryer class we track runs from $23 to $128 a year. At $59/yr, it runs about $54 a year cheaper than the class median of $113, and it is about $36 a year more than the cheapest clothes dryer to run at $23.
What drives its running cost
At 4 cu ft, the Summit LDES248 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 2.68, below 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). CEF combines drying performance with standby and off-mode energy use; for a given drum size, a higher CEF means less energy per pound of laundry dried, and heat-pump models usually post the highest figures in the class.
- Drum capacity. Drum capacity sets how much laundry one cycle can hold, and heating a bigger volume of air generally costs more energy per cycle.
Common questions
Is the Summit LDES248 cheap to run?
Yes, relatively. At $59 a year it ranks #79 of 615 clothes dryer models we track, in the cheaper part of its class to run.
How much does the Summit LDES248 cost per month?
Roughly $4.9/mo, spreading the $59/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 317 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $59 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Summit LDES248 for its size?
72nd 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.
