In the era when water heaters were not yet popular,The emergence of solar water heaters instantly solved the problem of "difficult bathing".At that time, the roofs of various communities were full of solar energy, even in rural homesA smash hit, the sale is called a hot one!
And, with the strong support of the state, solar water heaters are becoming more and more popular. But,Within a few years, the solar water heaters that used to be all over the roof disappeared overnight and faded out of sight.
When it comes to why solar water heaters canAll the rageIn fact, it was directly related to the economy at that time, so to speakA product of the times.
In the 90s, the economy of the cities was also very average, and the rural areas could be said to be very backward. At that time,It's really difficult to take a hot bath in winter.
In those days, it was good to take a bath once a week in the countryside. Boil very hot water before taking a bath, even at homeCook in a cauldron to boil hot water, then hang up the plastic bath tent first, put a bath basin in it, put a basin of hot water in it, let it heat up, and then take all the hot water kettles that can be placed next to it, and wash the bath in this way.
It can be said that it was very difficult to think about taking a bath back then. But,With the advent of solar water heaters, it has completely changed the status quo that there is no hot water for bathing, washing face, and washing dishes in rural areas, so that winter life has been changed.
When the solar water heater was just catching fire, who could use itJust like who had a TV in the village before, it can be said that it is a very worthy thing to show off.
Later, despite the improvement of living standards, people's requirements for life are getting higher and higher, and solar water heaters have also begun to popularize. It is used in almost every household in the countryside, and many people in the city.
But the good times didn't last long, because who would want toWhen I actually used it, it wasn't like that. And there isSubsidies for going to the countrysideOn the basis of this, solar water heaters have disappeared in the city, and they are not as popular as before in the countryside, so it can be said that they have "fallen off the altar".
For solar water heaters,It took only a few years from a smash hit to "falling off the altar"., so that the expansion of production scale of the business is not expected, which has also led to the closure of many solar businesses.
As for the most real reason? I'm talking about my real feelings after using a solar water heater for 2 years:
1. It is susceptible to weather factors
If you want a solar water heater to turn cold water into hot water, you have to rely on itSunlight to heat it up。In simple terms,On rainy and snowy days, solar water heaters cannot be heated, so they cannot be used.
But when it comes to winter,Southern cities are mostly cloudy and rainy, and the intensity of sunlight is not excessive, so solar heating is simply not enough to turn cold water into hot water.
If it is said that in the northern cities, the winter sun is not very suitable for solar energy at all, because the pipes will be frozen and burst, and electricity must be used to heat them, so the practicality is very poor.
The most speechless thing is,Migrant workers who have been working outside for a year, when they come home during the Spring Festival, there is no sun, and they can't use it at all, which is very sad. Even if you have hot water, you can't continue bathing once you run out, and you have to wait until the second time the sun shines, which is really troublesome.
2. Difficult to install
Solar water heaters must be installed in a location with direct sunlight, so it is best to install them on the roof of the building.
But for solar water heaters,Generally, the net weight is about 50 kg, and it is very inconvenient to transport from the ground to the roof.
When installing, it is very troublesome to fix because the roof has a waterproof design. If you encounter it, there isslope of the roof, then if you want to fix the solar shelf, it is even more troublesome.
In the following pipeline installation, it can be said to be very troublesome. Because to install the solar tube on the roof indoors, you need to get fromDedicated pipes through itThis pipe is often occupied by people, so it is very troublesome to say that it is very troublesome to pass through the pipe, and it will take several hours to get it right.
3. Waste of water
For solar water heaters, I want to beWhen hot water comes out of the tap, the cold water stored in the pipes must be drained first.
Every time you want to use hot water, you have to put cold water for a long time, which is a waste of tap water at home.
4. Unhealthy water quality
Once the solar water heater is installed, it isVery few people do cleaning and maintenance, which also causes a lot of limescale to form on the inner tank of the incubator.
When these scales accumulate to a certain extent, it will not only affect the heating time of the solar water heaterIt will also cause the hot water released to affect the health of the human body.
If you say that you will take a bath with hot water with limescale for a long time, first of allClogging the showerhead, resulting in an unsmooth water outflow. At the same time, letting this water come into contact with ** for a long time will also lead to a variety ofQuestion
5. The bath water temperature is unstable
In the winter, it is difficult to turn hot water into hot water through the sun, and you will find out when you take a bathThe water temperature is unstableAdjust the hot water position of the shower from time to time, otherwise it is difficult to reach the water temperature that you are satisfied with.
If you think it's just that the water temperature is unstable, you're wrong. Because in winter,If one person uses a solar water heater to wash the water heater in the bathroom, and someone in the kitchen turns on the faucet, the hot water in the bathroom instantly turns into cold water.
That is, solar water heatersOnly one faucet can be guaranteed to produce hot water, and two faucets cannot be guaranteed to produce hot water at the same timeThe reason is that the inlet and outlet water of the solar energy is a pipe, and the two positions open the faucet at the same time, which is equivalent to putting cold water on the solar water heater.
You can imagine what it would be like to take a bath in the bathroom and suddenly the hot water turns hot!
6. High degree of damage
For solar water heaters, maintenance can be a very headache.
This is due to the fact that the solar water heater is installed on the roof, due to the installation is not done well and suffers all year roundExposed to wind and sun, it is easily damaged to varying degrees.
When encountering extremely cold weather, such as strong winds, torrential rain, and even hail weather, it will be coveredBlowing down, pipe freezing and leakingand other phenomena, with a high degree of damage.
7. There are better water heater products to replace
The main reason why solar water heaters are no longer popular and "fall off the altar" isThere are so many alternatives.
Because as foreign products have entered the domestic market, people have seen more alternatives, likeElectric water heaters, gas water heaters, air energy water heaters, quick-heating water heaters, small kitchen treasures, electric heating faucetsWait a minute.
While people's living standards have been improved, they are no longer satisfied with the solar water heater to be affected by the weather, and they want the hot water at home to always be in the best state and heat with it.
At this time,Gas water heaters have entered thousands of households and have been recognized by more and more people。Even families who do not have the conditions to install gas water heaters will choose to use storage electric water heaters, because it is much easier to use than solar water heaters, no longer affected by the weather, and can be used at any time.
