For ...You can run many of the dehumidifiers on 12V. For about $10-15 on Amazon you can get a 12V timer. That is how I run the sump pump on my F-24 (also a float--either will start it). I have a very shallow bilge, so running the pump 1 minute per day has worked for me. My PDQ had 300W of solar and a robust 120V system that was always on, so running the dehumidifier on 120V was easy. If I were running a dehumidifier on a mooring on a smaller boat, like my F-24, I would use a 12V timer.<br /><br />Another option is a day/night switch, and only run the dehumidifier after dark. It will be more efficient and pull more water a night, when it is cooler. In the winter, this is also best, because the cabin will go above freezing during the day, allowing defrosting. You can get these in 12V also, and that might be even better, but I have not tested.<br />https://www.amazon.com/Diitao-Automatic-Photocell-Adjustable-Photoswitch/dp/B0BB6YQ9D7/ref=sr_1_16?crid=1TYE0XQ8LVJL7&keywords=day+night+12v&qid=1687730896&sprefix=day+night+12v%2Caps%2C91&sr=8-16<br /><br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5399150767029697926.post-79736238396505866722023-06-24T20:09:28.713-04:002023-06-24T20:09:28.713-04:00Hi Drew, Just read your article in Practical -sail...Hi Drew, Just read your article in Practical -sailor about using a dehumidifier while on a mooring. You say you use it on a timer so that it only runs at night. The photo shows the timer plugged into a 110v outlet. Since you're on a mooring, I assume that you're running an inverter to power the timer, as well as the Eva unit. So, the inverter draws power to make 110v, the timer uses a tiny bit of power and then the Eva uses some (50-70w?). Do you have an estimate of the total draw when Eva is running and the draw of the inverter and timer during the day when Eva is off? My Aims inverter draws 50w, the same as my frig (frig only cycles on about 40% of the time). The inverter is usually turned on for the microwave and TV, otherwise it's off. Is there a 12v dehumidifier and timer? Thanks for your insight.Anonymousnoreply@blogger.com
