For pressurized and supercharged solar types, supercharged type is better.
1. Advantages and disadvantages of pressurized solar water heaters: Advantages: The principle is that when hot water comes out, cold water can be replenished into the water tank at any time and water can be supplied. at any time, the pressure of the water outlet is the same as that of tap water. Disadvantages: It consumes more electricity. Electric heating should be used frequently. The pressure type uses heat pipes for heating. Water is not leaking in the pipes. The transmission fluid is used to conduct the contact temperature of the heating plate. in the water tank barrel is very high. It is very alkaline in Beijing. It is easy to spread and burn.
2. Advantages of pressurized solar water heaters: Superconducting heat pipes conduct heat in one direction and have a low capacitythermal city, so the starting temperature is relatively low and the temperature rises very quickly. Superconducting heat pipes have strong low temperature resistance and do not freeze in ultra-low temperature environments. The inner tank of the pressure water tank is high-frequency welded and can be directly connected to the tap water system and work automatically. There is no shortage of vacuum tubes inside the pressurized solar water heater. Water greatly improves the thermal efficiency of the product, and the vacuum tube will not freeze or crack in cold weather. Even if only one pipe of the solar pressurized water heater breaks, the water heater can still work normally and it works fully automatically under pressure, which is very convenient. Disadvantages: The pressure water heater has a large surface area when installed and has a certain effectinsulation on the ground. The hot water pipe of the pressure water heater is very long, which wastes a lot of water each time it is used. The water heater heats the water when the sun shines all day. Hot water cannot be guaranteed at all times and comfort in this area is relatively poor. The lighting panel of the pressurized solar water heater is installed on the roof. Its installation on the roof will affect the overall beauty of the building, especially in high-end residential areas, which will damage the roof waterproofing layer over time.
How to install a booster pump for solar water heaters
Boosting a solar electric water heater means adding a booster pump to increase the water outlet pressure, so that you can wash more comfortably; the insulation cycle is less than When the set temperature is less than 5 degrees Celsius, electric heating cwill automatically start heating up to the set temperature and will automatically stop when the set temperature is reached. which circulates hot water in the pipes, so that the hot water can be discharged as soon as it is opened, the water point is further away from the water heater, it is necessary to add a pipe circulation pump , which will consume electricity and thermal energy.
The steps to install a solar water heater booster pump are as follows: 1. Determine the location of the booster pump: The booster pump should be installed on the outlet pipe of the heater -solar water, usually on the top or side of the water heater. 2. Prepare installation tools: You need to prepare wrenches, screwdrivers, tape and other tools. 3. Turn off the water source: Before installing the booster pump, you must turn off the water source to prevent a flowExcessive water flow will cause installation difficulties or burst water pipes. 4. Install the booster pump: install the booster pump on the outlet pipe of the solar water heater according to the instructions and secure it with screws. 5. Connect the power supply: Connect the power cord of the booster pump to the power outlet and make sure the power cord has good contact. 6. Test the booster pump: Turn on the water source and check if the booster pump is working normally. If there is any abnormality, it should be adjusted or replaced in time. 7. Complete the installation: After the installation is completed, you should check whether all the pipe connections are firm to ensure the normal operation of the booster pump. It should be noted that before installing the booster pumpBefore proceeding, you must understand the water outlet pressure of the solar water heaterand the load capacity of the booster pump to ensure safe use of the booster pump. At the same time, the installation location and pipeline connections of the booster pump should also be operated in accordance with the requirements of the instructions to avoid water leakage or other safety issues.
