cuian01 0 Report post Posted September 12, 2008 I found that there are two types of storage water heater, 1, box shape, 2. cylinder shape. Some salesmen told me that the cylinder type is better with stainless steel water tank, more durable. and some others told me that the box shape is much cheaper with sort of high-tech water tank. Have you ever used any of those storage water heaters? What's your idea and experience? Thanks Share this post Link to post Share on other sites
