====== Excessive humidity ====== | |
| |
Excessive humidity causes multiple problems for RVers: mold/mildew, damage to electronics from water condensate, discomfort, and diminution of insulative properties of items like sleeping bags. | |
| |
| |
Common causes of high humidity / condensation include: | |
* living fulltime in the RV | |
* humid weather | |
* propane appliances | |

[[http://amzn.to/2h8QeIO|{{ https://images-na.ssl-images-amazon.com/images/I/41j242B4RdL._AC_US160_.jpg}}]]Humidity due to constant habitation can be reduced with increased ventilation, as with [[hvac:roof vent|roof vent]]. | |
| |
Humidity due to use of [[fuel:propane]] or [[fuel:butane]] can be reduced with increased ventilation and the use of more efficient propane appliances. | |

In some cases [[http://amzn.to/2h8QeIO|a dehumidifier]] may be necessary. Bitty recommends [[http://amzn.to/2gWtXyB|the Eva-dry Edv-1100]].((http://www.cheaprvliving.com/forums/Thread-Condensation-AGAIN?pid=109733#pid109733)) Some users drain the receptacle into a sink or other drain.((http://forums.sailboatowners.com/index.php?threads/12v-dehumidifier.167895/#post-1170395)) | |
Eva-Dry confirms the [[https://www.eva-dry.com/dehumidifiers/edv-12v-power-cord/|12v adapter for this model]] passes 12v and not 9v;((https://boondockplan.wordpress.com/2016/12/06/eva-dry-12v-humidifadapter/)) this should make it easier to wire from [[electrical:12v:intro|house power]]. | |
| |
Peltier devices are power-hungry and run constantly; the dehumidifier might best be used as an [[electrical:solar:nonessential|opportunity load]]. | |
