Each has its own advantages and disadvantages. In terms of safety, the water storage type can be heated in advance and then unplugged before using hot water, which is very safe; the instant heating type needs to be turned on constantly to use hot water, which is poor safety; In terms of energy saving, the water storage type heats a large amount of water, and once it is not used, it will slowly cool down, and the entire water tank needs to be warmed up when used again with instant heating type; can be used when boiled, and it will be used when no water is needed. It uses electricity, relatively speaking, it saves electricity. In terms of power, although the water storage type needs to be preheated, the power is relatively small, while the instant heating type needs to heat the water instantly, the power doesit therefore be higher. Another point is that the water storage type can adjust the water temperature and flow, but the instant heating type will reduce the water flow as the water temperature increases. My personal suggestion is to use the water storage type, because it takes a long time to come out and the performance and technology are relatively guaranteed. But the most energy efficient and practical option is solar energy. Spend more money to buy better solar power, and you won't need electricity in normal use all year round!
Which is better, a solar water heater or an electric water heater?
An electric water heater is generally over 2,000 watts. When fully charged, it can boil water for several kilowatt hours per hour, costing one to two yuan. In summer it must be heated twice. the night. It uses energyie solar or photovoltaic. He can save about five yuan, or about 100 to 200 yuan per month, and one thousand yuan per year. Compared to the cost of solar energy, the savings can be recouped in one or two. years, the use of solar energy is therefore environmentally friendly and energy efficient. . .
I'm not a professional, so let me speak from my own experience: From the point of view of installation, use and maintenance, electric water heaters are best. From an environmental point of view, solar water heaters are better. If you want to choose a solar water heater, I would like to give some suggestions:
1. Choose one of better quality.
2. Choose one with a larger capacity. The capacity is preferably 2 to 3 times the water consumption of the day. Once the water runs out during the day, there will be no more hot water left in the. water heater, so that itcan quickly meet the water temperature needs the next day.
3. If the water heater is installed on the roof, the ground you live on should be as close to the top as possible. The pipeline is too long and there is too much cold water in the pipeline. You have to empty the cold water every time you use it. It is very pointless to drop it (the wall-mounted water heater is not as efficient as the one installed on the roof).
4. Scale should be removed after 3-5 years of use (depending on local water quality conditions).

Solar energy is not suitable for the southern climate, because the sunshine duration in Shixing is not long and the temperature water in springemps and in winter is far from what you need, if supplemented with power it will consume too much performance. The water temperature is too high in summer, but it is perfect in autumn! And the maintenance cost of solar energy is relatively high! Electric water heaters are divided into two types: instant heating type and water storage type. Instant heating type is more convenient to use. I recommend you to try itThe Riston constant speed thermal series water heater has a fast heating speed, can be washed immediately after being turned on, and can automatically detect water quality and automatically eliminate corrosion factors in the water to protect the inner tank and components, which can save a lot of maintenance costs.

Solar energy, don't take a shower if there is no sun, don'tdo not take a shower if the sun is not enough in winter, electric water heater, no restrictions Time and temperature, the principle is that electricity is necessary, I think electric water heaters are better

I think solar water heaters are better! My house is equipped with solar energy, which can basically meet the daily demand for hot water. It is not very convenient during the rainy season, but now solar energy can be used for electric heating, and the speed is also very fast! And the most important thing is that it is economical and ecological! However, one must choose the right manufacturer for the installation, and the most important thing is to check the after-sales service.
