TCL H50D46W against the category
That's 36.5% above the dehumidifier category average of 378 kWh/yr, and ranks 427 of 546 certified dehumidifiers for annual running cost, 1 being cheapest. The category average comes from every dehumidifier ENERGY STAR currently certifies (546 models), not an outside benchmark, about $26/year above that average at the national rate. See the methodology page.
What sits beside it in the ranking
TCL T50DC3S ($97/yr, 516 kWh/yr) costs a little more to run than the TCL H50D46W. TCL H50D44W ($97/yr, 516 kWh/yr) costs a little less.
Same brand, different models
TCL makes 16 ENERGY STAR certified dehumidifiers; this one ranks 10 of 16 for running cost, between the brand's cheapest, the T25DC9R at $53/yr, and its priciest, the T50DC9SPB at $100/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.
Shopping for a new one
At $97/year, this is on the expensive side for a dehumidifier; the cheapest certified model in this category runs about $20/year, worth knowing before buying either the TCL H50D46W or its replacement.
Worth comparing a few current certified models before deciding.
Protecting what you have
Whether or not the TCL H50D46W ever needs replacing, a repair is the more common failure for a dehumidifier, one a protection plan budgets for ahead of time.
Sourcing
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. Ranked 427 of 546, the TCL H50D46W 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.
