The specific installation location of the solar water heater should follow the following principles:
1) The solar water heater to be installed should be placed in a convenient location. According to the current structure of the house, it. This is usually a flat roof or a sloping roof. Convenient fixation is the main factor in selecting the location. Choose a roof location that is closer to the designated flue, air outlet or pipe well.
2) The installation location of the solar water heater should be within the lightning protection zone of the building. Particular attention should be given to places subject to frequent thunderstorms if the building does not have facilities such as. lightning rods, lightning protection facilities should be added.
3) The solar water heater must be placed in a sufficiently sunny place and with a long exposure time,but it cannot block the lighting of adjacent solar water heaters.
4) Other requirements not covered should be implemented in accordance with the provisions of the solar water heater installation instructions and the requirements of local properties and users. The principle is to ensure that the solar water heater is placed safely. and operates normally without violating current regulations.
Solar water heaters have been recognized by the public as a clean and pollution-free heating method, and various problems have always arisen during their use. A solar water heater called Black Porcelain that uses ceramic materials instead of conventional glass vacuum tubes and metal flat plates as heat collectors. There is no need to worry about pipe explosions, frozen pipes in winter, long-term air drying, reduced lifespan and. question of theefficiency of heat collection.
Solar water heater installation requirements and steps
The installation of solar water heaters is usually carried out by professionals, but the quality of current professionals varies, as well as the manufacturing quality of certain workers. is not good. Okay, homeowners can also gain knowledge about solar water heater installation diagrams in advance, to ensure construction quality. Next, let's learn the installation diagrams of solar water heaters and the installation precautions of solar water heaters with the editor. .
1. Installation Steps of Solar Water Heater Installation Diagram
1. The solar water heater should be installed in an unshaded place, with the main body facing the sun (around 10 degrees due to ambient temperature). south or west), and fixed firmly to prevent the water heater from being knocked overby strong and violent winds;
2. The assembly sequence of the main body of the solar water heater: first assemble the support frame, then install the insulated water tank, then install the vacuum collector tube, and finally install the diffuse reflector (reflective grid)
3. When installing the vacuum collector tube, first snap the tailstock into the tailstock; plate, then apply a little lubricant such as detergent to the outer wall of the annular opening of the vacuum collector tube, and put on the dust ring. Then align the axis of the vacuum tube with the axis of the vacuum tube hole in the water tank, slowly screw it into the water tank, and then carefully screw it back onto the tailstock. When installing the water heater, you must first install the two outermost vacuum collector tubes of the insulated water barrel, adjust the gap between the vacuum tubes and the holes of thewater tank to make them uniform, then install the remaining vacuum tubes
4. After the main body of the water heater is assembled, the installation of the pipeline can be carried out. There are five holes on the covers on both sides of the insulated water tank. You can flexibly choose the installation method according to actual needs, but no matter which installation method you need to do. Install the ventilation pipe correctly, with ventilation at the top and overflow at the bottom to avoid inflation or deflation of the water tank due to poor ventilation
5. The vacuum collector tube is air-dried without water to prevent the vacuum collector tube from bursting when cold water suddenly enters it at high temperature. If the water heater is installed under the hot sun, you can use a parasol to provide shade or fill the vacuum collection tube with water and turn on the water immediately.nt once all installations are completed. It is recommended that the water supply time be at night or in the morning when the temperature is not too high.
6. To ensure that the water heater can be used normally in the cold winter. It is recommended that water supply pipes be insulated or drained to prevent pipes from freezing and cracks affecting use;
2 Precautions for installing solar water heaters
1. low temperature and short solar sunshine in winter, when installing solar water heater, exterior pipes. The exhaust overflow pipe and exhaust overflow pipe should be covered with rubber-plastic insulation pipes first, and then insulated with thicker polystyrene materials to prevent water from freezing, which makes hot and cold water flow up and down smoothly, and even damage the tank of thesolar water heater.
2. If the pipeline does not pass through the flue but outside the building, the pipeline should be fixed on the side wall of the building to ensure safety and aesthetics when connecting the pipe fittings at the corner of the building. water. of the solar thermal water heater, use a wrench or pipe wrench to hold the faucet before attaching other fittings.
3. Pay attention to weather conditions, especially temperature. If the temperature is not too low, if there is still hot water in the water tank after using water that night, refill it immediately; the temperature is relatively low at this time, the water must be refilled the next day; if the weather is bad the next day, raining or snowing, the water should be refilled according to the water situation at home and try not to do so. fill it with water.
The above is the schematic diagramsolar water heater installation and solar water heater installation precautions presented by the editor of Lightning Home Repair. Solar water heaters can use hot water without using electricity, so they are welcomed by many homeowners. In order to use Practical, please pay attention to the build quality during installation. If you want to know
Installation angle of solar water heater
1. /p>
1. The installation of solar energy requires that the structure of the house has a sunny side and does not block the facade.
2. Determine the installation position so that the horizontal distance between the collector and the water tank is less than 250cm; greater than 20 cm, and the copper pipe connecting the two must always maintain an upward trend without being affected or obstructed by buildings.
3. Make sure there is enoughspace for the sensor to be installed towards the south, east, south, east, west or west of the building to ensure continuous sunlight. solar energy time is not low. At 4 a.m.
4. Pay attention to the structure of the balcony. Design the interior pipelines in advance before installation to ensure that the interior is in perfect condition after installation.
2. Solar water heater installation - installation steps
1. RootDetermine the installation location of the solar collector depending on the sensor size of the selected solar water heater. (Solar energy is generally installed on the balcony)
2. Determine the installation location of the solar water tank according to the actual situation on the balcony .
3. According to the installation location of the solar water tank, determine the location of the power socket and outletused for cold and hot water pipes on the balcony.
The installation angle of the solar water heater mainly refers to the installation angle of the sensor. The orientation of the sensor is best due to south and can be changed within 10° east or west. facing south, ensuring no blocking of sunlight and increasing sunshine time. When installing, you can first use a compass to find the true south position and mark it.
When selecting the installation tilt angle, if it is used all year round, the tilt angle can be equal to the local latitude; if used in summer, the tilt angle is the local latitude minus 10°; ; if used in winter, the local latitude angle plus 10° can be considered °, the requirements for the inclination angle of the solar water heater installation are not static.
Solar water heatersres fully absorb the sun's energy and convert the sun's light energy into thermal energy to heat the water temperature. When choosing the installation location of the solar water heater, you should choose a place with sufficient energy. sunlight and where it can be fixed. It is best not to install it in winter blocked by buildings and trees, generally choose vacant places such as balconies, roofs and roofs.
