fridgidaire dehumidifiers

I got tired of watching my 25 pint dehumidifier fail to keep up in my new room so I went and upgraded to the 50 pint. I could not believe how inefficient the 25 pint one was. uses 410W's for 25 pints well the 50 pint only uses 615W's. I was pretty excited at the store thinking this dehumidifier will keep my humidity under control without using more energy.

Once I got it home and working I realized it was gonna save me ALOT more. Not only is it more efficient it also produces a TON less heat. What is lost in efficiency on the 25 pint model is apparently all transferred to heat. During lights out my room was running the AC just from 25 pint dehumidifier when it was under freezing out. I am using the 50 pint now and the AC isn't even close to running.

Then during lights on under 32 degrees my AC was kicking even with the air cooled hoods running. Now its not running at all and I even had to turn down the temperature on the light exhaust as the room was getting down under 80(normally keep it at 86).


Just thought I would put this out there for those people who might benefit from upgrading. The 70 pint is also nice and more efficient then the 50 but not as far off.

Thanks, my two rooms just went sealed so dehuey's are needed even in winter. I was wondering how I would keep up come summertime.

How much did the Frigidaire cost, and are they still a quality brand?

The 50 pint wasn't that expensive at all I think it was about a 184 at lowes. I have been happy so far with the new one. The old one just put off to much heat(25). I quess I really won't know until those 95 degree and humidity days roll around. Not matter what brand you get watch out for the efficiency of the models because of the excess heat.

Damn bro, your story sounds exactly like mine. I got tired of my little 25pt running all day so I went to Lowes a week ago and bought a Frigidaire 70pt for $254.
What a difference! It is so quiet that I thought the compressor wasn't coming on, lol.
I let my room go up to 85% humidity and it brought it down to 45% (where I set it) in minutes, and stays there all day/night.
Granted, it's no Sante Fe but for the home grower it is a pretty damn good unit.

As soon as I got home and had it running I instantly regretted not getting the 70 lol.

From what I saw those Lg look okay as far as efficiency. The entire reason I posted this was so people who had the smaller inefficient dehumidifiers would see this. I know for 99% of growers who enclose there rooms heat is always a fight. For me it became an issue because I don't like my window AC unit to run in the winter lights on or off during normal temperatures. I attributed my excess heat in lights off to the new room and its good insulation. Now I sit and watch the dehumidifier cycle off and on as I watch the room temperature rise and fall.

I wish I had the money for one of those santa fe units. Every KW you pull out of your room is less electricity you are gonna use.

You can't even find dehey's in my parts these days, they won't put them back on the shelves until spring. Right now It's all humidifiers and space heaters.

I see a Frigidaire, or two, in my future.

Do you guys get to plumb the drain on yours, or do you have to empty them all the time? Has anyone used a condensate pump?

I got my dehumidifier at lowes they carry them all year where I am at. Call around your local hardware stores and you might get lucky. If not you could always order one online from one of those stores.

I don't plumb mine to a drain. My dehumidifier is elevated on a small platform in my room. The hose drains into a container underneath the platform. I just use that water on my plants.

i was under the assumption that dehuey water should be drained and not used because it is distilled... i have checked ppms on the water coming out and it is around 30... so it cant be that bad right?! Thanks for the info on the dehuey.. i have a lg 30 pint right now and it just isnt keeping up. running pretty much 24/7 to keep it at 50%... its old and i got it for 50 of of cl. i drain mine via a 1/2 " hole i punched in the front of the condensate bucket. i had my hose hooked directly to their drain and it kept overflowing... i rekon not enough pressure to push it thru my 10ft of 1/2" tubing before it gets to the drain. Mine is hung up almost @ the ceiling.

Upgrade that 30 pint and you will see a big heat reduction. You can use the water from a dehumidifier as long as its not leeching hard into your water. I use the dehumidifier water along with RO water but I am currently switching from the RO water to regular tap water. I will start mixing the tap water with the dehumidifier water which will take down my high EC water a bit and move up the EC on the dehumidifier water.

As long as the hose continually travels downhill to the drain without any kinks it shouldn't overfill your bucket. I usually put some plumbers tape around the male threads just incase. One other thing I do is I don't use my AC or dehumidifier filters. Instead I just spray down the coils once a week with clean water. For me it helps them run a little better although some people might not agree.

I would love one of those 110 pint santa fe units. It uses less electricity then the 70 pint per day frigidaire.

My portable AC died yesterday... but I find that the central air
in the house will keep tent at 78F/55%RH, without it when lights are on.. go figure.

Problem is lights out.. RH is 65%-68%, I'd like it lower...
The portable AC was digital on/off and would not restart with a timer, or after a power outage,
it must be turned on manually. Is it the same with this Dehuey?
Do the controls need to be analog for use with a timer or controller?

And can one duct out the exhaust/heat? I already have a hole in the wall
for the AC exhaust.

This unit will restart after power failures. The first 3 minutes after restart it won't start condensing. If you put it on a timer you will be fine. Every dehumidifier I have seen was meant to exhaust in the area it is in. The hot air off of the dehumidifier has a low RH. Whats important is that you get an efficient one so that it produces alot less heat.

Good news, thanks.

There is a thread by hoosierdaddy : https://www.icmag.com/ic/showthread.php?t=95491&highlight=air+conditioner

that tells how to box up a windwo shaker, pulling air and taking air from outside the room, in my case that would be the garage..
the grow room being in a bedroom. I could do without condensate,
although I've learned how to deal with it but more heat I do not need. The house central air, alone, I'm finding, set at 71F keeps the tent 77-78F but RH is 65-68%.. and last half of bloom coming, I want 50%.

Is it configured so that I could I box up the dehumidifiers exhaust and duct it outside?

The window AC unit box is great but not really applicable for a dehumidifier. With a window AC unit the outside coils transfer the heat from the inside coils and the box takes the heat farther away from the room. This would mainly be for people who are trying to keep hot air away from the outside of there room or security or what not.

With a dehumidifier the hot air from the coil is what lowers the humidity in the room. As the air passes over the coils it pulls moisture from the air and heats it a little bit. If there is a way around this or a special unit I haven't heard of it yet. Even though an AC unit and dehumidifier operate on the same scientific principle they function way different.

I am kinda curious though do you have a sealed room? If you don't have a sealed room a dehumidifier is really a mute point. If your room is sealed and running CO2 then the room would be able to handle the slightly elevated heat coming from a dehumidifier. Every situation is different.
