Thor Kitchen DW24X8BA99
Rank #384 means 383 of the 709 dishwasher models we track cost less to run each year; the 64th efficiency percentile means it uses less energy for its size than 64% of those models.
What does the Thor Kitchen DW24X8BA99 cost to run per year?
The Thor Kitchen DW24X8BA99 holds rank #384 of 709 on running cost, at about $45 a year, an unremarkable but typical figure for the class. It uses 21.8% less energy than the U.S. federal standard model in its class, which would cost about $57/yr to run, a saving of roughly $12 a year. Efficiency-wise, once size is accounted for, it edges out 64% of the class, a modestly above-average showing. This class has no published efficiency-factor figure beyond annual kWh itself, so at 15 place settings (the class spans 2 to 18), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Thor Kitchen DW24X8BA00 at $45/yr runs a little cheaper and the Thor Kitchen TDW24C7 at $45/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 Thor Kitchen DW24X8BA99's $45/yr adds up to roughly $405 in electricity alone, before purchase price or repairs.

What drives its running cost
At 15 place settings, the Thor Kitchen DW24X8BA99 is a mid-size dishwasher for its class, which spans 2 to 18 place settings with a median of 14 place settings, putting it squarely in the middle of the class on the size lever that drives most of the cost.
- Place-setting capacity. Place-setting capacity is the main driver of how much water a cycle has to heat, and heating that water is most of a dishwasher's electricity use.
- Water heating. Most dishwashers have a booster heater that raises incoming water to sanitizing temperature; this heating step, not the pump or motor, accounts for most of a cycle's electricity use.
- Cycle length and drying method. Heavy or sanitize cycles run longer and hotter than a normal or eco cycle, and heated-dry options cost more to run than air-dry or condensation drying.
