Model
Big Chill BC24DW
Rank #104 means 103 of the 709 dishwasher models we track cost less to run each year; the 44th efficiency percentile means it uses less energy for its size than 44% of those models.
What does the Big Chill BC24DW cost to run per year?
Do the math and the Big Chill BC24DW's $42/yr puts it at rank #104 of 709, one of the more affordable dishwasher models we track to keep running. It uses 26.7% less energy than the U.S. federal standard model in its class, which would cost about $57/yr to run, a saving of roughly $15 a year. Normalized for capacity, it beats 44% of dishwasher models we track, an average result for the class. At 12 place settings, it is a small dishwasher for the class, which runs 2 to 18 place settings; size and efficiency are the two levers behind the figure above, and this dataset does not carry a separate efficiency-factor column for this class.
Immediately around it on the leaderboard, the Beko DUT36520*** at $42/yr runs a little cheaper and the Blomberg DWT 52800 **** at $42/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A dishwasher typically stays in service for somewhere around 9 years; over that span, the Big Chill BC24DW's $42/yr adds up to roughly $378 in electricity alone, before purchase price or repairs.
Also sold as: Beko DDT38530***.
By the numbers
The Big Chill BC24DW 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 Big Chill BC24DW adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Big Chill BC24DW costs about $420. That is roughly $150 less than a standard model in its class, which would run closer to $570 over the same ten years.
How the Big Chill BC24DW compares
The dishwasher class we track runs from $15 to $45 a year. At $42/yr, it runs about $2 a year cheaper than the class median of $44, and it is about $27 a year more than the cheapest dishwasher to run at $15. Against the US federal standard model for its class at about $57/yr, the Big Chill BC24DW uses 26.7% less energy.
What drives its running cost
At 12 place settings, the Big Chill BC24DW is a small dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, 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.
- Place-setting capacity. A larger dishwasher heats more water per cycle, so bigger capacity generally means a higher annual energy figure, independent of how efficient the unit is.
- Water heating. The booster heater that brings water up to sanitizing temperature is usually the single largest electrical load in a dishwasher's cycle.
- Cycle length and drying method. Cycle selection, eco versus heavy, air-dry versus heated-dry, moves real running cost more than most owners realize for a given capacity.
Common questions
Is the Big Chill BC24DW cheap to run?
Yes, relatively. At $42 a year it ranks #104 of 709 dishwasher models we track, in the cheaper part of its class to run.
How much does the Big Chill BC24DW cost per month?
Roughly $3.48/mo, spreading the $42/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 225 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $42 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Big Chill BC24DW for its size?
44th 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.
