Does anyone have any experience with the dehumidifiers that use the Peltier technology? They are smaller than compressor based models with lower yields, but I'm wondering if one of the larger ones might not work to help make the coach more comfortable in the humid summertime. We have used a large 70 pt compressor type dehumidifier at the house for years and it really makes the house much more comfortable. I could use a small 30 pt unit in the coach, but I don't want the noise nor the extra heat that's generated. So the smaller Peltier units look interesting as they should run silently. I see one unit that is supposed to remove up to 25 oz of water a day. Just wondering if anyone has tried one.

I live in Florida and can easily collect 1/2 to 1 gallon of water per day in the hot and humid summers there using the larger noisy dehumidifier. I think it will depend on the humidity levels in your location. I hope this helps.

25 oz a day (about 2 sodas) isn't going to make much a dent in the coach environment. Maybe a closed closet storing winter clothing that you rarely access during hot, humid summer at best. Open the coach door once and any gain on interior humidity levels will be lost.

A peltier does make for a good, small, active heat sink or a small closed area dehumidifier but in a coach you're going to need a lot of them to be effective. It's a pretty cool concept that will probably replace freon based heating and cooling someday once efficiency and capacity is improved.

I just bought an Ivation "mid size" Peltier dehumidifier from Amazon this week. We are wintering in our RV in Flagstaff, AZ so I cannot judge how it might work in the deep South in the summer (we are having a big snowstorm right now). However, I have noticed the windshield gets considerably less condensation with the dehumidifier than without. It is 14" tall and fits on the kitchen counter under the upper cabinets. It's fan makes minimal noise.
