Comparison between solar water heaters and electric water heaters
1) Easy installation: Solar hot water takes a long time to reach the room from the roof and needs to be installed in a place with enough time. sunlight, like a building. It is very inconvenient to install on the roof, balcony, etc. The electric water heater is small and beautiful and can be installed indoors.
2) Convenience: Solar water heaters need to wait a long time from the roof to indoors, and the water pressure is not enough, which will cause inconvenience for bathing. Electric water heaters heat up immediately when turned on. are compact and easy to install.

3) Price: Advantages of electric water heaters: hot water can be set at a constant temperature, the price is cheap and does not depend on the weather. Of course it consumes electricity, but you can turn it on just beforeto take a shower, so the power consumption should not be very obvious.
Solar water heater: It does not require electricity and is energy efficient, but it is highly dependent on the weather. It may not be very suitable for the rainy season in the south.
When taking a bath in your own backyard in a rural area, is it better to install solar energy or a water heater?
With the improvement of living standards, many rural areas have also undergone earth-shaking changes. People are increasingly concerned about cleanliness and hygiene and pay more and more attention to quality of life. The construction of public baths in rural areas should be based on local conditions, combined with actual local conditions and people's living habits. Taken together, the following factors should be considered:
1. mainly given the popularity of ground energyarea and natural gas. For example, in some areas, most families have already used solar energy and can bathe at home, but market space is limited.
2. In many places, public baths only have a "semi-annual market", that is, there is a market in winter. For example, many rural areas in the South have natural swimming beaches (ponds, rivers). ), and almost no one goes to public baths in summer.
3. Cost factors. Most rural bathhouses are renovated from their own houses, but detailed calculations must be made on the costs of water, electricity, natural gas (or coal), etc.
4. Positioning and pricing. The positioning of rural bathhouses is very clear, i.e. the large rural population, so everyone's affordability must be taken into account when pricing.
5. Sanitary conditions,The cleaning and disinfection of public baths must also be taken into account, as well as the discharge of waste water, etc.
When purchasing solar water heaters in Guangdong, you should pay attention to the fact that the thermal insulation performance should be consistent with the local climatic conditions. Design solutions for thermal insulation of products. in northeast China and Guangdong province are completely different. Of course, if you don't use it in all seasons, you don't care too much. You can even buy a solar water bag or find an oil drum with red paint on the outside and put it in. the roof and connect it to the hose to take a shower. At least in summer there is enough sun. This can guarantee safe boiling water every day. Many current Guangdong solar water heater products can be used in allaspects and can be used in both poles. Therefore, climatic differences are not a problem. Even in Manzhouli, the northernmost part of China, there must be one when used under conditions of. minus 40 degrees. Money can satisfy you. Additionally, as there is abundant sunshine in Manzhou, electric assistance can be very effective.
I used to use solar power, which is really good without electricity, but it can't be used when it rains, especially if it rains for a long time, then it doesn't work. There is really no way to take a shower, then in winter It is also impossible to take a bath frequently. The water always takes two or three days to wash, which is not enough for just one person in the family. I recently purchased a domestic water heater. It is very convenient to take a shower. I generally use solar energy to produce electricity.'electricity and I use an electric water heater on rainy days. can wash it directly at home. Although the electricity bill is high, you can still go to the public bath. If you have to pay for a bath, you might as well wash it at home. I live in a rural area, I think both are necessary and I can buy both.
From the perspective of the daily use cost of water heaters, Guangdong solar water heaters mainly use the kinetic energy of sunlight to heat water. In areas with long daylight hours and sufficient sunlight, there is no point in using them. them. Questions are better. If the family has a large population, the Guangdong solar water heater model is reasonable and the operation method is appropriate, the cost-effective effect is more obvious. It is no problem to save about 1,000 yuan a year. If you wishIf you want to be more cost-effective when using Guangdong solar water heaters, the choice of size and the use of purchased volume are also very important. Choose volume size based on family size. The volume size is chosen to ensure that a water tank can be heated at any given time of the day and the room temperature is set to between 60 and 70°C, which is sufficient for a family to take a shower. If the volume and temperature are selected in this way, the automatic heating function of Guangdong solar water heater will hardly be used. Rainy days are excluded.
Rural houses are generally not very high. Two or three stories are considered high. Guangdong solar water heaters are usually assembled on the roof. The inlet and outlet pipes of solar water heaters do not need to be too long. , unlike thisows of large cities. Multi-story water inlets and outlets consume a lot of water in rural areas, because the houses are not too high, it is easy to assemble with Guangdong solar water heaters, and it saves money. the water. and money. Guangdong's current solar water heater is full of water, enough for four or five people to take a shower, and the water temperature can be maintained for three days without cooling. The average farming family has only four or five people, and Guangdong. The solar water heater is just enough for a family to take a shower. For home water heaters and liquefied gas water heaters, one uses electricity and the other natural gas, which increases the cost of living compared to both. Guangdong solar water heaters are both economical and environmentally friendly.
