I'm a plumber by trade so I have access to old copper and steel hot water cylinders but no welding torches. Also I'm very capable with sheet metal but I've heard galv isn't ideal. I don't want to use the wrong materials that are dangerous. Does it need to be insulated? What are the best heating methods? I'm from new Zealand and we don't use charcoal much here so I'm thinking a wood fire or an element. Any advice or ideas would be great
