Model
Honeywell Home DHM065R4000/U
Rank #357 means 356 of the 519 dehumidifier models we track cost less to run each year; the 96th efficiency percentile means it uses less energy for its size than 96% of those models.
What does the Honeywell Home DHM065R4000/U cost to run per year?
The Honeywell Home DHM065R4000/U is a relatively costly runner for its class: about $93 a year, rank #357 of 519. Once capacity is factored in, it outperforms 96% of the dehumidifier models we track on efficiency, near the very top of the normalized ranking. At a IEF of 2.23, its integrated energy factor is the single figure that best explains how it earns its running-cost number.
Immediately around it on the leaderboard, the Aeric AERD501PF at $93/yr runs a little cheaper and the Aux ADT50V1 at $94/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A dehumidifier typically stays in service for somewhere around 8 years; over that span, the Honeywell Home DHM065R4000/U's $93/yr adds up to roughly $744 in electricity alone, before purchase price or repairs.
By the numbers
The Honeywell Home DHM065R4000/U normalized against its whole class, so each figure means something.
What it costs you over time
Running cost is an every-year number, so it compounds. At $93/yr, here is what the Honeywell Home DHM065R4000/U adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Honeywell Home DHM065R4000/U costs about $930. That is roughly $290 more than the class median, which would run closer to $640 over the same ten years.
How the Honeywell Home DHM065R4000/U compares
The dehumidifier class we track runs from $19 to $521 a year. At $93/yr, it runs about $29 a year above the class median of $64, and it is about $74 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 52.09 pints/day, the Honeywell Home DHM065R4000/U is a large dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, and larger dehumidifier models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light. The IEF of 2.23 on this model, above the class median of 2.01, measures integrated energy factor; it is the number to compare directly against another model's IEF if capacity is similar.
- Integrated Energy Factor (IEF). Two dehumidifiers rated for the same pints per day can carry very different IEF figures, and IEF is what actually separates their running costs.
- Water removal capacity (pints/day). Pints-per-day rating scales with the space it is built for, and that rating is the first driver of how much power the compressor needs.
- Humidistat accuracy. How tightly a humidistat holds its target humidity determines how much of the day the compressor actually runs, on top of the unit's rated capacity and IEF.
Common questions
Is the Honeywell Home DHM065R4000/U cheap to run?
Not especially. At $93 a year it ranks #357 of 519 dehumidifier models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Honeywell Home DHM065R4000/U cost per month?
Roughly $7.78/mo, spreading the $93/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 503 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $93 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Honeywell Home DHM065R4000/U for its size?
96th percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
