Efficient, or not, for a dehumidifier
Against the category average of 378 kWh/yr, this model uses 52.1% less, ranking 54 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 $37/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 Patiosunny PS1415DH50WT: OLIXIS AS-CSJ72XK-4D5WT-OL ($34/yr, 181 kWh/yr), then SMUG AS-CSJ72XK-4D5WT-OL ($34/yr, 181 kWh/yr).
Within the Patiosunny lineup
The Patiosunny PS1415DH50WT is the only dehumidifier from Patiosunny 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, $34/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
$34/year to run is the predictable cost of the Patiosunny PS1415DH50WT; a protection plan covers the unpredictable one, a repair bill.
