Tap water pressure is released from the vents, then water pressure when u take shower is gravity from top roof to your shower tap, so the most important thing on this type is to make sure vents open to air always. Otherwise the tank will be damaged because of high pressure from tap water. This type is the cheapest one among all our products, because it is simple structure, easy handling, higher efficiency from directly heating water through vacuum tube, we can call it open and thermosiphon system.
