This weekly report discusses the progress made in studying heaters. It includes: 1) An overview of how heaters work by producing heat from an electric current passing through resistive wire that can withstand high temperatures. 2) The components of heaters including insulating magnesium oxide, metal casings, and insulation testers. 3) Details on studying copper pot heaters and their ability to maintain constant temperature and continuous boiling. 4) The next steps are to better understand the operation and function of water heaters.
