There are two ways to solve the problem:
First, install a micro booster pump on the hot water pipe. Because the existence of the booster pump will accelerate the water flow in the hot water pipe, solving the problem of insufficient water flow. This type of booster pump has very low power and is relatively energy efficient.
Second, use a backup shower. The principle of a supercharged shower is: install an energy-saving pressurized water supply device at the end of the shower and communicate with the Venturi hole in the shower handle. When water enters the shower, outside air pressure forces the water to flow. faster, thereby increasing the speed by approximately 30% of the water outlet speed, which automatically increases the pressure by 30%.
Insufficient solar water pressure. Help
1. The chOrdinary solar water heaters are pressureless products and the pressure of the hot water outlet mainly depends on the size of the droplet. If the distance between the solar water outlet and the place of use is small, the hot water flow will be small and the pressure will be low when used. Especially for users who live on the top floor, they will feel it clearly when using. once again. The solution is to appropriately increase the height of the solar power to increase the height difference, or use larger diameter upper and lower water pipes.
2. The pipeline is long and has bends, which hinders the flow of hot water. The solution is to rearrange the pipes.
3. If there is a blockage at the water inlet or outlet or the upper and lower water pipes, the solution is for the after-sales service personnel to come to the house tor inspection.
How to use solar electric water heaters correctly
1. When refilling water when the weather is extremely hot and the water temperature is extremely high, you should use the water supply valve to limit the temperature. pressure and add water. It is strictly prohibited to add water after the water is used up. Fortunately, turn on the water before sunrise in the morning or two hours after sunset in the evening, to ensure the life of the water heater.
2. Each water heater has a vent at the top. It is normal for water to flow out when the water is full. It will stop after the water supply valve is closed. (This situation will not occur with water heaters equipped with temperature and water level indicators).
3. Electric heater: The power of the electric heater is 1500 W. If used on cloudy days or inwinter when the water temperature is not enough, do not plug it in for a long time. The power should be turned off when taking a shower. After plugging in, if the red light on the leak protection cap lights up, it means it is heating up, and if the green light lights up, it means the water temperature has reached 65°C.
4. When the temperature is not too low (7℃-5℃), after exhausting the water at night, there is still hot water left in the water heater (water in the vacuum tube), and it must be filled with water immediately. Reduce the internal water temperature of the water heater, reduce heat loss that night, and make full use of thermal energy.
5. If the temperature is particularly low, the water level in the water heater should be kept above 80%. If it is cloudy, please try to use water from the water heater and refill it immediately.
I think the requestof the poster can always be satisfied. Suppose the lift is increased by 5 meters (adding the 4 meter drop, the total is 9 meters, which is suitable for general use)
Consult the manufacturer for the maximum tube pressure water heater empty. (like 0.2MPa). Check the tap water pressure again (for example, 0.2 MPa).
Solution 1:
1. Install a pressure reducer on the water inlet pipe to reduce the tap water pressure to 0.05.MPa (5 meter head).
2. Install a 0.07 MPa safety valve on the overflow pipe (to protect solar energy in case of pressure reducer failure) and an automatic exhaust valve (or install a manual valve for first use ). Manual exhaust when not in use)
Note: Since it is difficult for ordinary pressure reducers to reduce pressure when no wateris used, the solar water replenishment valve must be closed when hot water is not used.
