I've been using DampRid bags and canisters over the last 2 months to suck as much moisture as I could out of my Catalina 250. I plan to continue this on an ongoing basis, especially on the hard in winter when I don't have continuous shore power available.

But today I found an interesting little 4 pint/day electronic "small room" dehumidifier at Home Depot for under $50. I bought it out of curiosity, but have not opened the box yet. The brand name is "Perfect Home," apparently a house brand that HD uses for sundries like furniture casters. They don't even have it listed on their website, so I can't get full specs. But the display unit had a 12 v brick adapter (didn't bother to check wattage). This unit looks similar to some other Peltier dehumidifiers available online.

If I do decide to keep it I will use it at the dock, and use the DampRid on the hard.

Have any of you tried any of these little dehumidifiers? Are they just junk, or do they have usefulness for a confined space like found in a 25' boat?

I realize that conventional wisdom is to buy two of the Nicro solar vents (on blowing in, the other blowing out), but on such a small boat I really don't have much horizontal cabintop space to locate them.

They had dehumidifier-water coolers when we were in Bermuda. I can't recall if they were solar-powered, as well, but wouldn't THAT be a cool watermaker to carry on board?

We used a mini dehumidifier (though looking more substantial than this one) and it worked for a while but had to be replaced under warranty.. when the next failed in a relatively short time we gave up and now run a Sears unit through the winter and shoulder months - impressively dry below (here on the wet coast), books and paper still crisp.

That thing looks supiciously like a HUMIDIFIER, not a DE-HUMIDIFIER...
It's not. The label was too tall to fit on my scanner. Something about the words "small room dehumidifier," printed above the part that I scanned, suggests that it's probably not a humidifier.

I opened the box & tested in my garage last night. Fan a little noisy, but not too bad. This morning it had a couple oz of water. I'm taking it to the boat tonight. I'll try to get some pics at some point.

nice little machine
By Brad from Des Moines, IA on 9/12/2009
Comments about EVA DRY Eva-Dry® Petite Electric Dehumidifier (EDV-1100):

I bought this dehumidifier for a basement room with carpet that is approximately 12x15 feet. It does a good job of keeping the room dry, even when the rest of the basement is not. It takes about two days to fill, and I find emptying to be very easy. The small size is nice because I can tuck it out of the way.
I wouldn't call it whisper quiet, but it's not bad. We also have a space heater/fan that we run during the winter, and this dehumidifier is quieter than that.

Pros:Compact, Effective, Lightweight
Best Uses:Dank Basement, Summer Humidity
Primary use:personal
Bottom Line:Yes, I would recommend this to a friend

Works Great!
By George from Portland, OR on 12/1/2008
Comments about EVA DRY Eva-Dry® Petite Electric Dehumidifier (EDV-1100):

Unit is just the right size for the forward cabin. Maintains humidity at about 45%. If your boat is over 25 feet or so a larger or second unit will probably be required.

Pros:Compact, Effective, Lightweight
Cons:Noisy for living space, Power light is bright
Best Uses:On a sailboat
Describe Yourself:Boat owner
Primary use:personal
Bottom Line:Yes, I would recommend this to a friend

Small but useful
By Susan from Oakland, CA on 1/19/2008
Comments about EVA DRY Eva-Dry® Petite Electric Dehumidifier (EDV-1100):

This dehumidifer has been very useful and it's working great.
The water tank fills up quickly in my basement so I have to continue to
empty it out. Probably would be better for smaller spaces.

Pros:Compact, Effective, Lightweight
Best Uses:Bathroom, Dank Basement
Describe Yourself:Homeowner
Primary use:personal
Bottom Line:Yes, I would recommend this to a friend

Best Uses:Summer Humidity, Used in walk in closet.
Describe Yourself:Homeowner
Primary use:personal
Bottom Line:No, I would not recommend this to a friend

I went to the boat for the first time in a few days. I checked the dehumidifier, and the reservoir was about half full - about a pint of water. This thing has no humidistat - it just runs constantly. I am quite pleased with this, as it is a little more than the DampRid canister was accumulating. And it's pure water instead of the DampRid's corrosive brine that I don't like having anywhere near my galley hardware. Plus, it seems to be sized to hold about a week's worth of condensate. It's too early to tell about long-term durability, and of course whether the amount is actually enough to make a difference vs. a "drop in the bucket" (so to speak). But so far it is meeting my expectations for a little $50 accessory.

No pics yet. It is a tall, skinny device (see specs on scan above), so potentially prone to tipping on a boat. I have it wedged between the front bulkhead of my aft berth and the berth cushion so that it will not tip. There still is no listing on the Home Depot website, so you need to go to the store to see it.

The dehumidifier has been in for a few weeks, and continues to remove about a quart of water per week. I have removed all the Damp-Rid stuff - glad not to have the corrosive liquid leaking out from the countertop canister, and the awful perfume smell from their closet hangers.

Someone asked for some pictures, and I finally got a couple. The first shows what the front of the unit looks like. But since the water reservoir and on-off switch are both on the back, I velcro-ed the thing, facing backwards, to the forward fiddle of my galley storage shelf (see second pic):

Thanks for the update! Did you say it can run on 12VDC? In a post you said the display model had a 12VDC wall cube but your pic seems to have a 110VAC cord.

Either way, I think I need one of these!

The cord in the pic looks like a 120v cord, but it's actually carrying 12v from the power brick. If you wanted 12v operation, I suspect that you could easily tap into that cord with a 3-way switch (A-B-off) to provide a selectable power source. That would be much more efficient than using an inverter to go 12 VDC → 120VAC → 12 VDC.

I have no interest in 12v operation at this time. Either I'm at the dock with shore power, or I'm sailing with the companionway open. If you're at a mooring ball I can see how you might run this off a solar cell, although the power brick is rated at 60w IIRC, so you'll need a hefty cell.

Be aware that the internal fan is a little noisy, and the thing puts out some heat, so operating while you are in the cabin for an overnight might not be preferable. I just use it for while I'm away during the week.

No I would wire it directly from my 12VDC circuit panel. I have only one spare circuit from my 120VAC panel, but several spares from my 12VDC panel. I would just run it when the battery charger is powered up from shore power.

Thanks!

I have a similar unit (the Eva Dry) as mentioned above. It's been working fine for the past several months and the container can fill in several days here in the PNW. It's very, very quiet, so I guess better than the Home Despot brand above. I'm going to rig up a tube at the top of the container so it will just pump the moisture into my sink drain and also use a timer so it won't be running 24/7.

Just curious, why don't you leave it running in the sink... it looks like if you removed the tank, it would just dump water directly into the sink. ;) Or if that makes you nervous....rig a hose to the output pipe that appears to be inside the tank, and then leave it sitting on the counter with the hose in the sink.

Would it be possible to put it over or in a larger bucket that could be drained out of the boat. That would be perfect for those of us that don't get down to the boat every weekend during the winter?

The dehumidifier has both a sensor to ensure that the tank is in place, as well as a float switch to turn it off when the tank fills up. So the best way to drain directly into the sink would be to install a tiny "through-hull fitting" in the back of the tank and attach a tube to run to the sink (or just put it in the sink).

I had been planning to do this, but it is way down on my very long list of more important safety improvements. Plus, lately I've been there to empty it out at least a couple times a week.

My basement dehumidifier is rigged to empty into a sump so I don't have to empty the tank. Unfortunately I have had two of them fail in the last 5 years, and they ran for [weeks? months? years?] before I noticed. (I discovered the most recent failure when I stuck it in my boat and got no condensation in the pan for a couple weeks.) So I try to run everything off the tank for at least a couple muggy weeks out of the year so I can gauge the rate of moisture removal.

I have been running a small dehumidifier much like yours in my 26 foot sailboat here in Melbourne, Florida for the past two months. The temps and humidity here have been terrible for the past month or so. I drilled a hole about 1/3 up from the bottom in the plastic reservoir and put it in the sink. I figure I can put a cork in it if I need to. Anyway, it is running like a champ! I closed off the nicro vent and the bilge has been dry for a while now. I think this was one of my "way better" ideas. Good luck with your unit.

I have been wanting to put in a nicro vent for awhile, and this was my stop-gap measure while I figure it out. I have a good place to put one vent, but you need both in and out vents to make it work right. I do not have a really good place to put a second vent - unless I remove a redundant bulkhead compass (shown in the upper left of my profile pic) and replace it with a cowl vent. But this stopgap measure may be better anyway. My bilge has always been bone dry, but I have an outboard, so no packing gland to worry about.
