How to install a solar water heater? Solar water heater installation steps

Solar water heaters are now spread all over the town, and its practicality and contribution are inexplicable. For people in remote areas, it is more likely to choose to buy them and install them themselves. Sometimes there are loopholes that may affect the performance of water heaters or cause serious accidents. So how do you install a solar water heater? The following decoration home decoration network Xiaobian will bring you the solar water heater installation steps for your reference.

How to install a solar water heater?

Solar water heater installation steps 1 , preparation:

(1) Prepare construction tools such as screwdrivers, wrenches, electric drills, etc.

(2) Open the water heater package and check whether the accessories are complete according to the packing list. The number of vacuum tubes is complete and intact; whether the electric heating is intact; whether the water tank body has dents; whether the supporting accessories are complete; only the control package is intact.

Solar water heater installation steps 2 , mounting bracket:

(1) Installation location selection. Generally choose the roof, the direction is to go north to the south, forward to the south (5) ~ 10 °, to ensure that there is no obstruction. The household pipeline should also be reduced, which can increase the sunshine time.

(2) Assemble the bracket. When installing, you should follow the instructions to assemble the front and back panels together, then use the wrench to tighten the screws without loosening. Then, the front and rear sides of the installation are diagonally supported to provide structural reinforcement.

(3) After installing the water tank and the vacuum tube, check all the screws and tighten them.

Solar water heater installation steps 3, fixed bracket:

Generally, cement piers, expansion bolts or wire rope fixing brackets are used. Of course, it is necessary to select the best fixing method for the roof. Wire rope fixing method: put the steel wire rope or large steel bar on the left and right frame of the front bracket and the left and right u -rings of the barrel bracket , and tighten with nuts, and stretch the four wire ropes or steel bars connected to the water heater in the four corners of the water heater, in the parapet or other Select the appropriate location, drill the expansion hook, and firmly connect the wire rope or steel bar to the corresponding expansion hook U -ring.

Solar water heater installation steps 4, install the water tank:

(1) Installation of electric heating. First open the dustproof cover of the electric heating port, loosen the screw inside, and then pry the bottom plug, check the built-in sealing rubber ring to see if it is tight, then put the built-in electric heating rod into it, and then restore it after pressing. Tighten the bolts.

(2) First place the water tank on the assembled bucket support, bolt the water tank to the bucket bracket, and tighten the connection nut between the bracket and the bucket bracket so that the two ends of the water tank are equal to the left and right ends of the bracket, and the center line of the vacuum tube is The front brackets are parallel in plane, and then the silicone sealing ring is placed in the inner barrel flange to be flattened.

Solar water heater installation steps 5, install vacuum tube:

(1) Installation of the stem. Install the vacuum tube holder first, and install the lower part of the collector tube, and install the tube holder at the specified position of the bracket.

(2) Intubation. First check the sealed silicone ring in the inner tank of the insulation tank, and then check whether the tail of the vacuum tube is damaged. Then check the transparency of the coating like mercury and check whether the nozzle has machining burrs and roundness. The outer tube of the vacuum tube is sealed into the vacuum tube and is about 1 (5) cm . The soap tube is used to fully wet the tube mouth. The right end of the vacuum tube is used to protect the tail end of the vacuum tube. The second is to facilitate the intubation force. Insert the vacuum tube in the direction of the vertical nozzle, push it evenly into the water tank with force, insert it and return it to the tube seat, so that all the vacuum tubes are installed in turn.

Solar water heater installation steps 6, connected to the hot water pipe:

(1) Entangling the tape at the inlet and outlet, then attaching the pipe fittings and linking the special pipes for solar energy;

(2) The electric heating cable is closely attached to the outer wall of the pipe, and is fastened with a sticky tie;

(3) Install the sensor in the water level meter hole of the water tank mall, and use a thick polyethylene rubber tube to keep the outside of the pipe;

(4) The water in the solar water tank is connected by tap water.

Solar water heater installation steps 7, wiring:

(1) Electric heating wiring. The red line is the live line, the two-color line is the ground line, and the other one is the zero line. Peeling, revealing about 2cm of copper wire, and putting on a heat-shrinkable tube for insulation and dustproof. Then connect the power cable with the three wires to the color, and then securely connect them with the waterproof insulating tape from the outside to avoid short circuit.

(2) Electric heating cable connection. Cut a bevel on the port of the electric heating cable so that its distance between the two lines is relatively far to avoid short-circuiting the link. Entangled with insulating tape to make it fully insulated, and align the end of the electric heating cable with the end of the tube, and fix it on the official road with insulating tape to make it close to the pipe wall. The other end is the intelligent controller terminal. If there is a booster pump, the pump wiring is connected in parallel with the electric heating.

Solar water heater installation steps 8, install intelligent controller:

(1) Positioning. On the indoor side wall, punch holes, then insert the plastic expansion tube, and fix the fixed base of the measuring instrument on the wall surface;

(2) The signal line of the sensor and the signal line of the control box are docked according to the mark, and inserted firmly;

(3) The thermostatic mixing solenoid valve should be installed horizontally, and the wiring of the solenoid valve should be connected to the terminal block on the control box.

Solar water heater installation steps 9, commissioning operation:

After installation, power on the controller and run. If there is no problem, clean up the tools and clean. Finally, calculate and record the indoor installation parts and quantity, and check with the owner. If there is no error, please sign and approve the user.
