I've had my Eva-Dry 2200 dehumidifier for a bit over a month now, and since I just got the monthly statement from the marina thought I would share the data points on the experience so far of running it on the boat to keep the internal moisture down.
First of all, it appears to add about $3 a month to my electric bill at the marina (we are charged separately for electricity), running 24/7. I can live with that.
Second, there have been reports of it overheating. To be more specific, the transformer (which steps it down from 120V AC to 12V DC) gets very warm. But it has never gotten so hot that I cannot hold it in my hand. I would most certainly recommend that the transformer have good ventilation, however. I keep it on top of a metal stove top, with plenty of air flow around it. I suspect that the 6-amp draw is right at the engineering limit of the transformer. I do not trash Chinese stuff necessarily, but they do not appear to do the over-engineering that I am used with with American-made stuff. If it says 12 volts at 6 amps then that is probably all that it is capable of doing. (I have a 30-amp 12-volt power supply at home which is doing nothing since I got inactive on ham radio, so may just use that instead).
