Copper Coil Solar Heater for Hot Water

solar heater Style NO.GSIH-052 Copper Coil Solar Heater for Hot Water Feature: 1.These tanks can be used in combination with existing electric/gas mains pressure water heaters, or even as stand alone low pressure hot water systems with the addition of electric elements or external gas boosting. Ideal for use as low pressure thermal stores, the pre-heating is available with the addition internal coil heat exchanger. 2."Pre-heating" solar water heater provide mains pressure via a high efficiency copper coil heat exchanger located within the tank. The way in which the mains pressure solar collector heats water is the same as the non-pressure solar collector. Rather than using the water in the tank directly as the non-pressure does, the type uses a 40m copper coil. A heat exchanger inside the tank provides more than 1.2m ² of heat transfer area. 3.When cold water flows through the coil it absorbs heat from the water inside the pre-heating tank. The tank is therefore a thermal store. 4.Working principles The main body of Solar Energy Water Heater pre-heated solar system consists of four parts, vacuum tubes, heat preservation tank , assistant tank and support frame. The chief heat-collected part is the vacuum tubes (infrared-reflection layer, absorbance layer, anti-reflection layer), which are made up of two borosilicate glass tubes using full automatic equipment and advanced international magnetron sputtering technology. 5.The outside of the inner tube is coated with aluminum nitride layer or stainless aluminum nitride, which can endure a temperature up to 350°C. The coating absorbs sunlight exclusively (absorptance≥0.92, emittance≤0.09, 80°C). 6.The vacuum tubes absorb sunlight and convert the solar energy into power. Due to the thermo-siphon effect, the hot water in the vacuum tubes flows into the tank and the cold water enters into the vacuum tubes.

Installation must be completed by qualified plumbing professionals. 3. Before installation, please check the collectors first. If the bottom of tube is silver, the tube is good. If a tube has a white or clear bottom, it is damaged and should be replaced. Please exchange them this way: Unfasten and remove the plasic cap on the bottom, then pull the broken tubes out along with the direction of the collector, then replace a good tube and install the cap. Please do not to damage the copper heat pipes inside the glass tubes. 4. Do not expose the tubes to sunlight, otherwise the inner tube and heat transfer fin will become very hot. The outer glass surface will not become hot. Avoid exposing the collector to sunlight until the liquids are inside the manifold. 5. If two or more collector units are used on the roof, please use connectors to connect the collectors, so that the connecting is durable and solid, without any leakage of water.
