Bosch Dry 4000 against the category
That's 3.4% below the dehumidifier category average of 378 kWh/yr, and ranks 301 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 $2/year below that average at the national rate. See the methodology page.
What sits beside it in the ranking
AUX ADT35V1 ($69/yr, 369 kWh/yr) costs a little more to run than the Bosch Dry 4000. Noma iQ 043-8847-6 ($68/yr, 363 kWh/yr) costs a little less.
Same brand, different models
Among Bosch's 2 certified dehumidifiers, this is the priciest to run, $17/year over the Dry 2000, the brand's cheapest.
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.
Is it worth replacing?
The Bosch Dry 4000 is already efficient for its category at $69/year. If you're shopping and comparing options, this is roughly what a well-chosen new dehumidifier costs to run.
Compare current ENERGY STAR certified dehumidifiers before buying.
Protecting what you have
A dehumidifier like the Bosch Dry 4000 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.
Sourcing
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. Ranked 301 of 546, the Bosch Dry 4000 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.
