What sits beside it in the ranking
ZAFRO D026W-50Pt3M ($95/yr, 504 kWh/yr) costs a little more to run than the Waykar CHWA150PA. Waykar CHWA150A ($95/yr, 504 kWh/yr) costs a little less.
Same brand, different models
Waykar makes 39 ENERGY STAR certified dehumidifiers; this one ranks 33 of 39 for running cost, between the brand's cheapest, the CTH30A at $22/yr, and its priciest, the CTH150PB at $97/yr.
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
Running above the category average, $95/year is exactly the kind of number that makes a newer, more efficient model pay for itself faster.

Protecting what you have
Whether or not the Waykar CHWA150PA ever needs replacing, a repair is the more common failure for a dehumidifier, one a protection plan budgets for ahead of time.
