Product Description

Non-pressured solar water heater Water Tank: 1, SUS****2B Inner tank 2, Polyurethane foam insulation 3, Stainless or aluminum support 4, Trivalent element evacuated tube 5, Electromagnetism or ball valve(optional) 6, Electrical boost heater (optional) Working principle: 1, The high quality vacuum tubed absorb the solar autraviolet ray, then heat the cold water in the vacuum tube 2, The hot water rise in the top of the water tank , and the cold water sink to bottom then heat by solar collector.So the whole system is always circilating continuously 3, The electromagnetism or ball valve can perform the water supply automatically, the water in the tank is not sufficient, the electromagnetism valve will open its valve, the tap water flow in the water tank, if the water is full, it will close the valve automatically Feature: The DENO-P*1 type has the stainless shell, so it can be used in the acid rain area, the A**1 has aluminum alloy, the support is very light, Besides, it has *5years long life span, and the vacuum tubes can work individually, so if the only one of them can't work , it won't influence on the ***** spare parts can be changed freely, it is suitable for the many resident buildings.
