Waykar CTH120A: running cost
At 343 kWh/yr, the Waykar CTH120A's ENERGY STAR certification puts it cheaper than most models in its category to run against every other certified dehumidifier.
That $64 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.
How the Waykar CTH120A compares to other dehumidifiers
Against the category average of 378 kWh/yr, this model uses 9.3% less, ranking 284 of 546 dehumidifiers tracked here for running cost. 546 certified dehumidifiers, one average, about $7/year of daylight between it and this model; the full methodology has the rest.
Neighbouring models
Right next to the Waykar CTH120A on that list: TCL W32D93 ($64/yr, 343 kWh/yr) runs slightly less, while Waykar CTH120B ($64/yr, 343 kWh/yr) runs slightly more.
Same brand, different models
Ranked 19 of Waykar's 39 certified dehumidifiers, this sits between the CTH30A ($22/yr, the brand's cheapest) and the CTH150PB ($97/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.
Weighing a replacement
Efficient as certified dehumidifiers go, $64/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
A dehumidifier like the Waykar CTH120A 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.
How this was checked
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. Ranked 284 of 546, the Waykar CTH120A sits in the middle of the dehumidifier category, see the guide to why your state changes this number for the other half of the math.
