Model
Bosch WAW285H1UC
Rank #46 means 45 of the 388 washing machine models we track cost less to run each year; the 23rd efficiency percentile means it uses less energy for its size than 23% of those models.
What does the Bosch WAW285H1UC cost to run per year?
The Bosch WAW285H1UC runs for about $16 a year, landing it near the bottom of the cost table at rank #46 of 388 washing machine models we track. Its size-adjusted efficiency percentile of 23 suggests its capacity is doing more work than its efficiency to keep the headline cost down. The IMEF figure of 2.2 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 Blomberg WM72200W at $16/yr runs a little cheaper and the Electrolux ELFW7437*** at $16/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 Bosch WAW285H1UC's $16/yr adds up to roughly $160 in electricity alone, before purchase price or repairs.
By the numbers
The Bosch WAW285H1UC 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 $16/yr, here is what the Bosch WAW285H1UC adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Bosch WAW285H1UC costs about $160. That is roughly $40 less than the class median, which would run closer to $200 over the same ten years.
How the Bosch WAW285H1UC compares
The washing machine class we track runs from $7 to $58 a year. At $16/yr, it runs about $4 a year cheaper than the class median of $20, and it is about $9 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 2.2 cu ft, the Bosch WAW285H1UC is a small washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, and smaller washing machine models generally cost less to run for the same job, all else being equal. Its IMEF of 2.2, below the class median of 2.76, reflects integrated modified energy factor: a higher figure means it wrings more useful work out of every kilowatt-hour, so it is the efficiency lever to weigh against raw size.
- 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 Bosch WAW285H1UC cheap to run?
Yes. Its $16/yr running cost puts it at rank #46 of 388, below what most washing machine models we track cost to run.
How much does the Bosch WAW285H1UC cost per month?
About $1.3 a month, which is the $16 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: 84 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $16 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Bosch WAW285H1UC for its size?
23rd percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
