Re: [DIY] Dehumidifiers

 

Laren - Of course you are correct...!

I said I was omitting tiny details, the likes of which we might thrive
upon, but would drive many a layperson, bonkers.

2 brands, one 600 watts and one 650...
The 600w MIGHT be more efficient, and ALSO remove more water.
It is likely it will cost more. Or more efficient and remove the same
or almost the same amount of water.

But if a 500 w and a 700w, while likely a 700 will be more
efficient, it may or may not be so...

You might ask the salesman what size sells most often here.
Size, not brand, etc. THEN ask brand. Might even check
consumer guide. Ask about warranty details, too.


Humidity, the size of your house, etc, all come into play.
A lot more money may or may not be a wise investment.
If a 700w runs 15 minutes and shuts off and turns on and
off, it will be somewhat short lived.,, As compared to a 600w
that runs 20 minutes and rest for 20.

The 700, in THIS example, uses 7/6s as much electricity.
Both run the same amount of time. If the 600 is adequate,
*all else being equal,* or nearly, get the 600. If the 600 is
hugely less efficient, it's a bad deal. It will run far longer
to do the same water removal. Take paper and pen to this
job.

Maybe report the numbers here, and we can give a better
opinion. It's hard to describe the better, of two invisible things.

Hi Bill; Efficiencies vary greatly, so that is not always true. A dehumidifier is basically an air condeitioner that puts its heat back into the room. Energy efficiency of dehumidifiers is measured in liters of water removed per kilowatt-hour (L/kWh). Even amoung Energy Star models, efficiencies vary from a low of 1.2L/kWh up to 4.17/kWh. a variation that indicates nearly 3 1/2 times the efficiency. (uses less than 29% as much energy for the same amount of moisture removed) Non Energy Star models will use even more energy than the worst of the Energy Star models. Larger capacity models are easier to make energy efficient.
