Dehumidifier in cabin

aero3113

Has anyone stuck a home dehumidifier in their cabin? I had one sitting in my basement not being used so I figured I’ll give it a try. I don’t have any smells or mold issues but I did put damp rid containers in that pick up some moisture. I set it to 45%, curious what the water bin will look like in a few hours.

We used to run one on my dads sailboats all summer long, leave on the dock when we go sailing, huge difference. Since the AC is a huge dehumidifier I’ve never ran one on my power boats but if I had your set up I definitely would do that in the spring....

@Liberty44140 , do you run your AC 24/7 throughout the summer, even when your not using the boat?

I often leave it in humidity mode when I leave for the week. In that mode it comes on every 4 hours and if the temp has risen it lowers the temp 2 degrees, helps a lot with humidity during the week.

I run one of the air circulating fans for rv and boats and that seems to do a good job.

Is humidity mode the fan icon on the control panel?

aero3113

I’m pretty sure this is the same control panel that’s in my 330.

I did not realize there was a humidity mode.

I just read that if you press all three buttons (heat, cool and fan) it puts it in humidity mode. Is this true? Definitely nice to know it can do this.

Think it was the fan and power botton at the same time for 3 seconds. I will check with admiral when I get home.

Close but no banana:

HUMIDITY MODE:

While the system is on, press the POWER and the DOWN buttons simultaneously to enter the humidity or moisture control mode. The characters "HU-1" will appear in the temperature display. Every four hours, the fan is started and air is circulated for thirty minutes. During this time the air temperature is sampled and entered into memory. The cooling cycle is then started and continues until the temperature is lowered 28F. The compressor is allowed a maximum of one hour running time to reach the desired temperature. Four hours after the temperature is satisfied or the compressor times out, the cycle is repeated. During the cycle, the cool LED will be lit when the compressor is running. Humidity mode is provided to maintain a specific temperature and humidity range when the vessel is unoccupied for extended periods of time.

Yep Ian nailed it. Hit those two buttons, and you see the HU1 and you are in humidity mode. Yes I had the same controller as you. Works well. Something is off on that though as it lowers the temp 2 degrees, not 28 lol! Maybe it’s 2.8, I don’t know. Then when I get to the boat on power it off, wait a few seconds and then power on and it’s back to AC...

Aqua_Aura

So every 4 hours it will turn on and lower the temp 2 degrees then turn off?

Liberty44140

Yea but it will run a max of 1 hour so if it takes more than an hour to bring it down then it may not
come down a full 2 degrees

I have a home one i keep running all the time. It sits on the counter with a hose to drain to the sink. Personally i think it makes a huge difference.

I know a few people that do that. Seems crazy to me as it could spring a leak, but these guys don't seem to care..

A lot of members at me club leave their AC running all the time. I put mine on dehumidifier mode when I am not there.

Always see boats at the marina with what I assume is a/c discharge...but maybe it is dehumidifier mode running...I trailer and use damp rid which makes a huge difference...

McGarnicle

I use humidity mode but thinking about getting a dehumidifier and let it drain into the sink while the boat is sitting 

aero3113

I’ve thought about leaving it in the cabin on the countertop and drain into the sink while in the water. But make sure you secure it, would hate for it to fall off. I just don’t know if I want the extra hassle of removing it each trip.

I run my air conditioner in humidity mode when am not on the boat. It seems to help. 

aero3113

About 20 hours of run time and there’s a decent amount of water in the bin. Not humid at all but started to rain this morning. Hopefully it’s pulling moisture out of the boat where needed.

davidbrooks

This is the one i have for my cabin.  I also bought it with the 4 yr addl Amazon warranty so when it breaks i can just get a new one.  https://www.amazon.com/gp/product/B06XS7694G/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

With my boat on a lift, I just put out some damp rid at the end of the weekends.  Seems to do the trick.  The admiral has quite the nose, so she'll let me know at first sign of dampness.

I need a solar one!

4 days and over a gallon in the catch bucket.

Wouldn’t you pull the same amount of water out of the air in your back yard at this time of year?

aero3113

I’m not 100% sure, the boat is shrink wrapped and the door and hatches are closed. Its been in the 40’s with not much heat here.

aero3113

Curious to see how it will look on Thursday.

aero3113

A week later and there is less water in the bin. I want to say that the floating ball is about 1.5 inches lower then last weeks picture (bad pic below). Again I don’t know if it’s pulling out of the air or boat. The weather has pretty much been the same for the past two weeks. I think if the water is significantly lower again next Thursday it’s definitely drying out the boat.

Charleston I can pull a gallon out of my house, mid-summer, in 4 hours. We don't need a hurricane water supply, just a genny and a dehumidifier...
