Free Hot Water for Life? My DIY Solar Coil Heater

Forget expensive gas or electricity. I’ve cracked the code to unlimited free hot showers using a simple DIY solar coil heater. Off-grid in Portugal, we use "low-tech" science, (black pipe and sunshine), to get boiling hot water for zero Euros. In this video, I show you the system that’s been giving us hot showers for 5 years, even on some sunny Portuguese winter days. In this video, I show you how I put it together, and how it works. I didn’t cram every detail into this video, but if you’d like a full how-to tutorial, drop a comment below and I’ll make one. 🛠️ Materials used: – ~50 meters of 25mm black poly pipe – Wood for the frame (free/scrap) – pipes, fittings & connectors – Sunshine & Low Tech Awesomeness 🎥 Shot off-grid with second-hand tools, limited means, and big dreams.
