Senville SENDH-22AEN1X: running cost
ENERGY STAR certifies the Senville SENDH-22AEN1X at 278 kWh/yr, one of the cheaper models in its category to run for its category.
That $52 is priced at 18.8¢/kWh, the average of all 51 state rates this site tracks. Your own state's rate is one click away.
Efficient, or not, for a dehumidifier
Against the category average of 378 kWh/yr, this model uses 26.5% less, ranking 152 of 546 dehumidifiers tracked here for running cost. That average is drawn from all 546 dehumidifiers ENERGY STAR currently certifies, not an outside number, a $19/year gap from this model at the national rate. Full sourcing is in the sourcing notes.
Right next to it on the list
A rank or two either side of the Senville SENDH-22AEN1X: Seasons SD22CA1 ($52/yr, 278 kWh/yr), then LEVOIT LDH-H251S-WUS ($53/yr, 281 kWh/yr).
Within the Senville lineup
The Senville SENDH-22AEN1X is the only dehumidifier from Senville that ENERGY STAR currently certifies, so there's no same-brand model to weigh it against here, only the full dehumidifier category.
Lifespan
NAHB's Study of Life Expectancy of Home Components does not publish a figure for dehumidifiers, so no lifetime cost is shown here rather than a guessed one. The annual and monthly figures above stand on their own.
Weighing a replacement
Efficient as certified dehumidifiers go, $52/year is a reasonable baseline if you're comparing what else is on the market.
Worth comparing a few current certified models before deciding.
If you're keeping it
At $52/year just to run, a dehumidifier is worth protecting against an unplanned repair bill on top of that.
Where this number comes from
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. The full Dehumidifier category page shows all 546 dehumidifiers ranked by cost; the state-rate guide covers the half of this number that isn't the appliance.
