I need a de-humidifer

[mchero]

Like to hear from full timers who have purchased a de-humidifier for winter. Don't want a full size due to amp draw but don't want too small to be ineffective.
Like to hear from others using de-humidifiers.
Purchased a small Eva-Dry but its not working well. Sending back.

Suggestions?

Thanks

I need one too. Here is a site called the air geeks that advise the best of the quiet ones.

RELATIVE humidity is just that.

Relative

It is a different universe to reduce humidity from 70% to 50% when the temperature is 50F rather than 80%

A 500 watt unit could do it. A waste of time and money to try it on 200 watts.

Add it up.

When looking at Amp draw, remember that those small boutique dehumidifiers are not as efficient in operation as the cheapest full size residential unit. Looking at the specs, you would need at least 6 of those units to match the efficiency of a small standard residential unit. So in practice, a single small efficient standard residential dehumidifier will cost less to purchase, use less electricity compared to several of those mini table top units, and it will do a much better job keeping you comfortable with less hassles and need for attention.

GordonThree 80% of rated output on a continuous load. But RV's because they "plug in" are exempt.

Burned plugs are the end result of going over that 80% figure.

Though I have had a 30 amp female Cameco burn when it was drawing less that 15 amps. (shore power was only 15 amps).

Absolutely! To each their own rig thank you.

Good point S Davis. Thanks for the reply.

You will get some heating from a dehumidifier as well.

Hmm, I guess to each their own.

I use a 1200w heater, a 600w heater, a 90 pint GE dehumidifier, a Sam's ice maker, all while running my fridge on electric.

30 amps is 3600 watts although the government says we must derate this some percentage.

Now if it's time to run MW or toaster, I turn the 1200w heater off first

Chemical desiccant based units might work for storage but not in a lived in coach.

Not going to rely on the E.M.S or switching devices on/off.

Not going to use the on board furnaces. As you should know the are VERY inefficient. Will use extend-a-stay and a ventless propane heater ONLY during daytime hours.

Thanks for all the suggestions! Good info!

Have always had a 30 pint dehumidifier in all our boats and RV's. Unless conditions warrant it, we take them off when using the boat/RV.

We use an electric water collecting unit often kept in the shower. Best investment ever. We can dry laundry over night. Condensation does not exist in our hybrid. Bought at Home Depot

We have a GE 30 pint that during periods of high humidity we dump twice a day! We very seldom have any moisture on the windows, and if we do it is just a small strip along the edge. We winter on the Oregon Coast.

Have you already tried the roof vent plus most distant window from vent plus electric heater by the window? (oil filled preferred).

OP's signature says they have 1000 watts solar, and I'm sure a generator on top of that.

I've used this Frigidairein a room at my work that had poor AC. Temp wasn't a big problem but humidity was. It held a 600 square foot room at 50% in TN in the summer.

My preference is the type WITHOUT a pump. Pump failure would be ugly. All you need is a slightly elevated spot where it can drain continually, either to plumbing or outdoors.

+10 on that. With a dehumidifier, the bigger, the better.
