DIY Solar RV Heater – Hot Air Collection for your RV

This post was updated on March 15th, 2024

When it comes to figuring out ways to implement a RV heater the options are endless and the inefficiency of most of those options are the stuff of legend. Today I want to introduce you to a very creative and interesting do it yourself idea for creating a solar powered RV heater that you can make with mostly low cost easily attainable items. In this video the application is for a brick and mortar home but the principle will apply to your RV as well. It should also mean that you wont need as many or a large of units to get the job done. The producer of the video guide mentions that for an RV heater you should consider a series of “mini solar panels” that could be used along with small computer fans to force the air in. When there is enough sun to make the fans run then there is enough sun to heat your RV. If you decide to move forward with this you will be entitled to free heat for the life of your RV compliments of the sun! Video below.
