RE: [Cal_Boats] Dehumidifiers!

Yes, John, I also had one that did not shut down when it froze up. It would then overheat from the ice obstruction. I was afraid to leave it on. There was this handy dumpster… :- ] As far as longevity goes, one would think that a dehumidifier is meant for a humid environment. Right? However, I think the environment they build for is more like a basement than a boat. I’m sure someone will sell a marine dehumidifier for five times as much money, if not ten.

My home dehumidifier would turn off the cooling and run the fan until the ice melted off of the coils then resume. It stopped doing that and now runs nonstop with frozen coils. I've stopped using it and haven't gotten rid of it due to the cheapest recycling payment of $25 to get rid of it is 20 miles away. The closer one wants $75.

They use a compressor to cool a coil of tubing, and moisture condenses on the coil. When the ambient temperature drops too much, the moisture freezes on the cooled coil. When too much ice builds up, the device stops working. They have some sort of sensor to shut off when the thing freezes up. Chris Campbell

Does that make it half price? http://www.defender.com/product.jsp?path=-1|6880|48359|328481&id=183451 I see that one has its performance specified -- at 80 degrees F @ 60% relative humidity I am beginning to think the market for these things is Florida in the summer, not San Francisco in the winter. Maybe I will go back to the ventilation theory. That theory says that the best you can do is to keep the boat at the same humidity as outside by moving air around and if you close it up, it will go to 100%. Those little heaters with fans are not trying to heat the air, they are trying to create convection currents to move the air around. Back to the drawing board. Great discussion, btw. Allen

Allen, the nominal on that part is 300 cubic feet. Even the inside of a CAL 20 is bigger than that?

I think that is probably close to what mine is. But doesn't matter, I am not spending $500 on one that might freeze up. Back to the vent idea.
