1. When the weather is extremely hot and the water temperature is extremely high, you should use the water supply valve to limit the pressure and add water. It is strictly prohibited to add water after the water is used up. It is best to fill the water in the morning before sunrise 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 will not happen with water heaters equipped with temperature and water level indicators).
3. The power of the electric heater is 1500W. If it is used on cloudy days or in winter when the water temperature is not sufficient, do not plug it in for a long time. The power should be turned off when taking a showere. 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.
6. When taking a bath, if the water in the solar water heater is used up and the person has not rinsed it, you can run cold water for a few minutes and user the principle that cold water flows and hot water floats to drain the vacuum tube. When the hot water inside is expelled, you can continue to shower.
7. After taking a shower at night, if there is still half of the hot water near 70℃ in the water heater tank, in order to avoid excessive heat loss (the less water , the faster the heat). loss), the water temperature should also be adjusted according to the water temperature. Weather forecasts determine the amount of water supplied. If the weather is good tomorrow, the water will be full; if it rains tomorrow, the water will be 2/3 full.
Detailed information:
Solar water heaters convert solar energy into thermal energy and heat water from low temperature to high temperature to meet the usagetion of hot water by people in life and production. Solar water heaters are composed of heat collecting tubes, water storage tanks and associated accessories. The conversion of solar energy into thermal energy mainly relies on heat collecting tubes.
The temperature of the sunlight surface of the collector is high and the temperature of the back of the collector tube is low, and the water in the tube produces a temperature difference reaction. The principle of heat. floating water and flowing cold water are used to cause microcirculation of water to achieve the desired effect.
Solar water heaters have entered thousands of homes with their green, environmentally friendly and energy-saving features. Our community has always adhered to the concepts of low carbon, consumption reduction and environmental protection. idiotconstruction of houses, each home is designed and installed with solar water heaters.
Baidu Encyclopedia - Solar Water Heater
Over the weekend, a colleague from the company moved to a new house, so he invited us to his house for dinner. Although the decoration of the new house is very simple, it is very warm. Arriving at the balcony, I found a strange device after listening to the explanation. Only then did Shi realize that it was solar energy. Turns out I don't need a water heater at home now, so I started using this thing instead. It doesn't take up space and saves energy! It really is a good deal after all. But in my opinion, shouldn't solar power be placed on the roof?
This is the first time I see this kind of wall-mounted solar power. So, is this type of wall mounted solar power good? Everything has two sides, andWall-mounted solar energy is no exception.
Let’s first talk about the benefits of wall-mounted solar power. Compared with general vertical solar power, wall-mounted solar power is more space-saving. Generally, wall mounted solar will be installed on the balcony wall. Nowadays, the floors of residential buildings are generally relatively high. If the house is a small apartment with limited square footage, wall-mounted solar is a good choice.
Compared to electric water heaters and gas water heaters, wall-mounted solar energy is more economical and affordable. It mainly uses solar energy to provide hot water. As long as there is enough sunshine, you don't have to worry about running out of hot water at home. Although gas water heaters and electric water heaters have hot water at all times, their use incurs gas and electricity bills.
From pRead, wall-mounted solar water heaters are safer because they make full use of the working principle of solar energy. There are certain safety risks when using gas or electricity. solar water heaters are safe. The coefficient is relatively high.
So, with so many advantages, what are the disadvantages of wall-mounted solar?
Wall mounted solar installs both the water tank and the flat panel collector on the balcony. After all, the space of the balcony is limited as well as the bearing capacity of the balcony. The balcony wall is limited, so there are relatively high requirements for wall-mounted solar energy (its own weight and the size of the water tank, etc.).
Compared with ordinary solar energy, wall-mounted solar energy is more expensive and the installation process is more complicated. The installation of wall-mounted solar energy requires the agreement of the ownerire. The internal systems and accessories are more complex than traditional solar, so the price is also higher.
