 How to buy solar water heaters
Should have a complete product specification, warranty card, logo, and so on the box, the appearance of fine products, reasonable structure, excellent material, fine workmanship and good after-sales service to ensure that there is.

       How to buy the water heater
General bath takes about 35kg-50kg per person of hot water (45 ℃). As a result of non-conventional solar energy, the event will not be able to produce hot water on rainy days, so the election to double the amount of water on the water heater, hot water heat will be sunny to rainy days the use of storage. In case of two consecutive days, the choice of dual-use photo-based, to ensure all-weather, all-year use of hot water are.

       Choose what kind of pipeline
As a result of water heaters are often placed on the roof, the house with a certain degree of pressure, high temperature hot water in summer (up to about 90 ℃), the outdoor temperature low (up to -10 ℃ below), and so on the actual situation, so the best selection of cross-linking Aluminum or composite reinforced plastic pipe or tube. With pressure, high temperature, low temperature-resistant, non-toxic tasteless, small heat capacity, heat loss, the characteristics of frozen winter is not easy. Galvanized pipe heat capacity, heat loss, water easily rust, pipes freeze in winter, it should not be optional.

       How water heater inspection
Water heater should be installed before the sun-and no place to the south, west Shaopian 10 degrees. Water tanks, pipes, valves and joints should be no leakage phenomenon. Not out of line pipe insulation, the phenomenon of missing packages. Water tank and vacuum tube plug the appropriate location of the vacuum tube  no damage, leakage, the phenomenon of white.

       How to raise the water temperature
       1. Do a good job up and down the water pipe insulation.
       2. Selection of small thermal conductivity of aluminum-plastic pipe and tube, such as cross-linking.
       3. Select high-capacity or lengthen the vacuum tube water heaters, hot water to stay in order to improve the basis of water temperature.
       4. Bath in the evening immediately after the Sheung Shui to keep water tanks full for the night to prevent me and a half high water temperature, the upper part of the night when the air cooling cycle.
       5. Man released after the water a little more water, hot water after the expansion of the water from the pipe back to the spillway.
       6. Even the two-day sun, sun or semi-box water 1 day, the temperature increase.
       7. Shower room temperature on the low side, Yuba or heaters can be used to increase room temperature. Bath at a low temperature, add more water to warm up.
       8. The use of electric heating devices, make up over access to water supply, power supply cut off after bathing.
