Wellsle YDL12P: running cost
The Wellsle YDL12P is certified by ENERGY STAR at 413 kWh a year, more expensive than most models in its category to run among dehumidifiers currently certified.
That $78 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
The category average is 378 kWh/yr; this model runs 9.3% above it, ranking 353 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 $7/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 Wellsle YDL12P: Midea MDUDP-35AEN8-BB0 ($73/yr, 388 kWh/yr), then Santa Fe 4047100 ($79/yr, 419 kWh/yr).
Within the Wellsle lineup
Ranked 2 of Wellsle's 3 certified dehumidifiers, this sits between the PD21MA ($34/yr, the brand's cheapest) and the YDL24P ($149/yr, its priciest).
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.
Shopping for a new one
The Wellsle YDL12P runs above its category average. If the dehumidifier you actually own is older still, likely well past ENERGY STAR's efficiency baseline when it was made, a current certified model could cost meaningfully less than this model's $78/year every year.

If you're keeping it
A dehumidifier like the Wellsle YDL12P is a real household expense whether or not it needs replacing yet; a protection plan is one way to budget for a repair rather than a full replacement.
