Non-pressurized solar water heater is such kind of a most economical system with high efficiency at the same time. It works depending on the gravity of water, so it's much better to be installed on the slope or flat roof as top as possible to get enough hydraulic pressure. A simple assistant tank can be equipped for tap water refill automatically or with an intelligent controller to control the startup of auxiliary heating device at the same time.
