Hi,
Am working to DIY homemade solar water heating project. Am looking for which type of material or water tank/bottle I need to use to store the hot water, which was maximum capacity to store hot water for long hours and must have resistance for external temperature in winter season. Am not much technical guy but I do believe that such material's container would be easily available in market, or what is the best way to design a homemade hot water resistant tank.
