Smeg DH24UWH
Rank #32 means 31 of the 615 clothes dryer models we track cost less to run each year; the 93rd efficiency percentile means it uses less energy for its size than 93% of those models.
What does the Smeg DH24UWH cost to run per year?
Among the 615 clothes dryer models we track, the Smeg DH24UWH's $42/yr running cost ranks it #32, comfortably in the cheap-to-run group. Few clothes dryer models we track beat it on size-adjusted efficiency; it edges out 93% of the class once capacity is normalized. At a CEF of 10.5, 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 Beko HPD24414W3 at $40/yr runs a little cheaper and the Whirlpool WHD5090G** at $43/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 Smeg DH24UWH's $42/yr adds up to roughly $546 in electricity alone, before purchase price or repairs.
By the numbers
The Smeg DH24UWH 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 $42/yr, here is what the Smeg DH24UWH adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Smeg DH24UWH costs about $420. That is roughly $710 less than the class median, which would run closer to $1130 over the same ten years.
How the Smeg DH24UWH compares
The clothes dryer class we track runs from $23 to $128 a year. At $42/yr, it runs about $71 a year cheaper than the class median of $113, and it is about $19 a year more than the cheapest clothes dryer to run at $23.
What drives its running cost
At 4.5 cu ft, the Smeg DH24UWH 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 10.5, 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 Smeg DH24UWH cheap to run?
Yes. Its $42/yr running cost puts it at rank #32 of 615, below what most clothes dryer models we track cost to run.
How much does the Smeg DH24UWH cost per month?
About $3.53 a month, which is the $42 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: 228 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $42 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Smeg DH24UWH for its size?
93rd 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.
