PVC clip 19mm for solar heater
Description
This summer i made a cheap solar heater for my pool. instead of using expensive rubber hoses i used cheap 19mm flexible pvc pipes. The pvc pipes are attached to a wooden panel using 3d printed clips. These can be printed from leftover pieces of PETG since they dont need a lot of filament. The solar heater worked flaweless trough the summer with about 3kw heating on a sunny day. PVC degrades when exposed to direct sunlight. The mat black spray paint protects the PVC and absorbs the heat at the same time. Easy to build, High efficiency, and cheaper then commercial solar products. The full build progress can be seen in this video: https://youtu.be/ZG2ll4oFxZo
