1. It is a common type of our products, non pressure means the tank can't bear pressure directly from tap water, so we make vents through which to release pressure. Tap water pressure is released from the vents, then water pressure when you take shower comes from the gravity from top roof to your shower tap, so the most important thing for this type is to make sure vents are always open to air. Otherwise the tank will be damaged because of high pressure from tap water.
2. This type is the cheapest one among all our products. Because of its simple structure, easy handling, higher efficiency from directly heating water through vacuum tubes, we can call it open and thermosiphon system.
