太阳能热水器

Characteristic: 1. The tank inside the building, the hot water loses less energy than the normal one. 2. The heater collector and the water tank is separated, that makes the system combine with the building perfectly, which will reduce the sightseeing for the building and environment around. 3. Back up with electric heater so that in the day without sunshine hot water can also be used. 4. Can be combined with gas or electric heater. 5. Max. Pressure: 12bar; Operating Pressure: 6 bar. 6. It can be used for other function, such as waring.Specification: 1. Inner tank: SUS304 2B food grade stainless steel. 2. Outer tank: White color steel or Stainless steel. 3. Insulation:? 55--60mm imported PU. 4. Copper coil: 15m each, diameter 12mm, thickness 1mm. 5. Heatpipe: Ati-freeze: -35C 6. Capacity: 100L, 150L, 200L, 250L, 300L, 400L, 500L Working principle: The collector absorbs solar energy and transmits it to the water tank through circulation. When the temperature of the collector reaches the set value, the controller starts the circulation pump automatically. The circulation pump makes heat-conducting liquid circulate automatically. Then the heat-conducting liquid transfers heat to water by heat exchanger in the tank to heat the water.
