This is a really Good Idea. I Would of loved to know what temp the water is on the other side. Something for people to note this was not connected to the Main water supply, because the flow would be to fast and the temps would be much lower. My opinion on how to improve the design, a) add more coils, b)the shape should be a pyramid c)lower the coils as close as possible to the flame d)use a self igniter control valve e)Use a plastic or rubber insulator instead of metal. Overall a very good build, and something we should consider making. Another note is the TESLA water resistor valve, this could help connect is to a powerful water main line yet heat up the water enough, the out flow would be slower of course.
