DIY Video:How to build an awesome Roof Top Portable ABS Pipe Hot Water Heater/Shower . Great for Camping/ Outdoors


    This video shows the build of a DIY solar powered, pressurized, roof top water heater and shower.This is done using an ABS 4 inch pipe, 6 feet long, which would give me a capacity of 15 Litres or 4 US gallons.This is an easy and inexpensive project that required minimal tools and just some basic plumbing parts.I started by installing the shutoff valve. I wanted the drain to be as low as possible in the pipe to avoid necessity of having to tilt the system. To ensure the valve retaining nut did not interfere with the pipe once it is glued into the, I positioned the nut away from the wall of the cap using a bolt, which is the same thickness as the wall of the pipe.I drilled out a 2” threaded cap and tapped in a radiator valve drain plug that I picked up at the local automotive parts store. This valve will allow me to release pressure from the tank should that be necessary without opening the drain shutoff. Also when open, this will allow a gravity fed system through the drain valve should for some reason I not have access to the air compressor.As a final step to improve thermal absorption of solar energy, I painted the surface with flat black paint. First I lightly buffed all the ABS surfaces with steel wool soaked Methol Hydrate. Then applied one coat of spray primer followed by two coats of flat black paint.

      This video series shows step by step the build and installation of a Simple Solar Air Heating Collectors that uses no electricity or batteries made from salvaged materials.The air enters at the center bottom of the collector, where an aluminum baffle spreads the flow across the width of the collector on the glazing side of the screen absorber. The air rises up between the glazing and the absorber, and eventually finds its way through the three layers of screen absorber and flows to the back side of the collector. The air then flows up the back side of the collector to the exit vent located at the top of the collector.
