Model
Midea MLHW52S7AWW
Rank #203 means 202 of the 388 washing machine models we track cost less to run each year; the 58th efficiency percentile means it uses less energy for its size than 58% of those models.
What does the Midea MLHW52S7AWW cost to run per year?
The Midea MLHW52S7AWW costs about $21 a year to run, a fairly typical figure for the class; it ranks #203 of 388. Capacity-normalized, it ranks ahead of 58% of washing machine models we track, right in the class's middle band. The IMEF figure of 2.76 on this model captures integrated modified energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Midea MLHW52S7AGG at $21/yr runs a little cheaper and the Miele WWD160 at $22/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A washing machine typically stays in service for somewhere around 10 years; over that span, the Midea MLHW52S7AWW's $21/yr adds up to roughly $210 in electricity alone, before purchase price or repairs.
Also sold as: Midea MLH45N1AWW.
By the numbers
The Midea MLHW52S7AWW 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 $21/yr, here is what the Midea MLHW52S7AWW adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Midea MLHW52S7AWW costs about $210. That is roughly $10 more than the class median, which would run closer to $200 over the same ten years.
How the Midea MLHW52S7AWW compares
The washing machine class we track runs from $7 to $58 a year. At $21/yr, it runs about $1 a year above the class median of $20, and it is about $14 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 4.5 cu ft, the Midea MLHW52S7AWW is a mid-size washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, putting it squarely in the middle of the class on the size lever that drives most of the cost. Beyond size, its IMEF of 2.76, above the class median of 2.76, is the class's own efficiency yardstick, integrated modified energy factor, and it is what separates two similarly sized models with different running costs.
- Spin and wash efficiency (IMEF). IMEF is this class's core efficiency yardstick; two washers with the same drum size can carry meaningfully different IMEF figures and running costs.
- Drum volume. A larger-capacity washer can wash more per load, which can lower cost per pound of laundry, but it also draws more water and energy per cycle if you are not filling it.
- Water heating. Most washers rely on your home's hot water supply, but internal-heater sanitize or hot-wash cycles use meaningfully more electricity than a cold or warm wash.
Common questions
Is the Midea MLHW52S7AWW cheap to run?
Roughly, yes. Its $21/yr figure is close to the class median, ranking #203 of 388, neither a bargain nor a splurge on running cost.
How much does the Midea MLHW52S7AWW cost per month?
About $1.73 a month, which is the $21 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: 112 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $21 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Midea MLHW52S7AWW for its size?
58th percentile once size is factored in, a fairly typical result for the class.
