How to Install a Home Solar Water Heater Return Water

The steps for installing the return water of the domestic solar water heater are as follows: 1. Determine the location of the water return pipe: Before installing the solar water heater, you must determine the location of the water return pipe. The return pipe must be located under the water heater so that the water heater can circulate water properly. 2. Install the return pipe: Connect the return pipe to the return inlet of the water heater. The return pipe should be tightly connected to the return port of the water heater to prevent water leakage. 3. Install a return valve: Install a return valve on the return pipe so that when the water heater needs to be repaired or cleaned, the return valve can be closed to prevent water from flowing back. 4. Connect the water return pipe: Connect the water return pipe to the return water inlet under the water tank of the water heater. The return pipe must be tightly coConnected to the return port of the water tank to prevent water leakage. 5. Test the return pipe: Once the installation is complete, turn on the faucet and check if the return pipe is working properly. If there are leaks or other problems, they must be repaired in time. Notes: 1. When installing return water pipes, relevant safety regulations must be followed to ensure safety. 2. Before installing the return pipe, you must carefully read the installation instructions of the solar water heater to understand the relevant installation requirements. 3. When installing return pipes, appropriate tools and materials should be used to ensure installation quality.

How to install the water circuit of the solar water heater?

1. When laying pipes and installing valves, you must first take a look at the gas interface and the input interface.eed and water outlet at the installation site, usually directly. hot on the left and cold on the right. Do not close them during installation. The main water inlet valve and the air inlet valve of the house are the only way to avoid the phenomenon of "water flooding the golden mountain".

2. Unpack the water heater packaging. Regardless of which channel you purchased the water heater from, you need to unpack it first to see if the accessories inside are complete. Of course, if you don't know much. about this, it is best to ask a professional Inspection staff, in addition, you can also rely on the manufacturer's accessories instructions. Typically, there is an expansion coil, flue, elbow, and shower head. However, the configurations of different manufacturers may be different, so it is best to ask clearly.

3. Pipe installationsmoke evacuation. This step consists of installing the smoke evacuation pipe. You should pay attention to it, otherwise it will pose a security threat for future use. Generally, the smoke extraction port is designed by the developer and the location is reserved. If there is none, then you must make an inclined opening yourself, high towards the inside and low towards the outside. In order to facilitate the adjustment of the water heater after hanging it on the wall, you must first install the flue pipe. You also need to pay attention to the metal material between the exhaust pipe and the wall, due to the temperature of the exhaust. The pipe is high when the water heater is used, and the plastic cover will be burned and even cause other hidden dangers.

4. Installing the gas valve. This step requires connecting the air inlet hose to the gas meter. Be sure to close the air inlet valve prbefore installation. Generally speaking, house gas should be supplied to both the stove and the water heater, so a three-way valve should be connected to the gas outlet of the gas meter. However, because the angle valve is difficult to operate, it is recommended to use a ball valve. Particular attention should be paid to the connecting pipes. Place rubber seals to prevent air leaks.

5. Preparing for drilling holes before installing the water heater on the wall depends on the location of the flue pipe. Measure the installation position of the water heater and make a recording on the wall. Use an electric drill to drill holes and drive in the plastic expansion tubes and screws. Install the gas water heater on the wall and connect the pipes. Hang the hot water device on the wall and seal the flue pipe with aluminum foil. Then connectthe water inlet pipe, the water outlet pipe and the gas pipe. prevent air and water leaks.

6. Test and inspect. After installation, check whether it can be used normally. The way to check for air leaks is to apply soapy water to the connection.

Installation of solar water heater: inside first then outside.

1. Indoor installation of solar water heater:

Select the position of the mixer, drill holes, fix the mixer, close the water valve and connect the tap water pipe. ; select the position of the shower head bracket, drill holes, fix the shower head frame, connect the shower head interface; connect the aluminum-plastic pipe of the water mixer; Depending on the situation, you can choose whether the aluminum-plastic pipe should be fixed with a seat clip; select the installation position of the watch, drill holes, fix thebase of the watch and install the watch. Because aluminum-plastic pipes are afraid of freezing, and PEX pipes are deformed after being heated, aluminum-plastic pipes are used indoors and PEX pipes are used outdoors, and both Pipes are connected by valves.

2. Outdoor installation of solar water heaters:

When choosing the location of the roof, first consider not shading or trying to be as close as possible; special solar pipes, ventilation ducts and smoke ducts. If there is really no other way, I choose to connect it from the outside to the house from the roof. The shorter the outer pipes, the better, which is good for heat preservation.

After selecting the location for the water heater, install the bracket and water tank. The screws at the bottom of the water tank cannot be tightened to adjust the angle. Insert the sensorr from the exhaust port or overflow port at the top of the water tank, connect the PEX pipe of the lower water inlet and outlet interface and cover the sensor wires, electric heating wires and PEX pipes with insulating pipes. Measure the distance between the water heater and the inner aluminum-plastic pipe, cut the PEX pipe, connect the PEX pipe connected on the roof to the room, and use a POM valve to connect the PEX pipe and the aluminum-plastic pipe. Also connect the wires to the watch.

Put in the vacuum tube. Fill a plastic spray bottle with tap water and dish soap, the ratio is: water 10: dish soap 1. First spray water on the seal ring, spray some water on the top of a vacuum tube, put on the dust ring, spray water again, rotate it into the sealing ring, rotate it and pull it to the base. AOnce all the vacuum tubes are installed, open the watch and check the temperature. If it shows around 40 degrees and the water temperature is above 20 degrees, you can refill the water. Plug in the electric heater socket and check if the socket light is on. If it is on, it means that the electric heating is normal.

Observe if there is a water leak inside or outside. Otherwise, wrap the insulating pipe with aluminum foil tape or asphalt rag once the water is full. Tighten the screws at the bottom of the tank. In this way, the solar water heater is installed. If you want to install a solar water heater and it is a new house decoration, you need to install the solar water heater first and then use the indoor waterway.
