Nowadays, when families renovate their bathroom, they often have only two options: one is to choose a water heater and the other is solar energy. In fact, both have their own advantages and disadvantages. There is no one better than the other. It all depends on the choice of each family.
Let’s talk about the water heater first. Most water heaters come in the form of water storage tanks. Easy to use, large water production, rapid heating and stable water temperature. Many ordinary households choose to install it. It is light, relatively inexpensive and takes up little space. There are many types of water heaters, and the hot water comes out very quickly and only takes a few minutes to heat up. ?
But in the same way, water heaters use electricity to maintain water temperature It uses a lot of electricity. Without electricityicity, heating is relatively slow; it is prone to scale and must be kept clean and hygienic for a period of time. Maintenance will be relatively frequent.
Let's talk about solar energy. Apart from the first installation, solar energy rarely causes problems in the future and electricity is no longer needed in subsequent periodsThus saving energy and money compared to water heaters . It is very environmentally friendly and has a long lifespan. It is very safe to use and will not cause poisoning or electric shock. The hot water in the water tank has a good temperature and is comfortable to use.
However, the disadvantages of solar energy are also obvious. The cost of the first installation is very high, and the water temperature after collecting the heat is always maintained at a constant temperature. If it is hot, the water tank will bea in a state of high temperature and pressure for a long time, which will promote aging and stripping of the seal ring and shorten the life of the water tank. So if you don't use it for a long time, you should find someone to drain it regularly or cover the solar. Another problem is that in winter, if the sun is not obvious, the water heater will easily run out of hot water.
How to make a solar water heater manually?
Solar water heaters are composed of vacuum collector tubes, insulated stainless steel water tanks, brackets, connecting pipes, etc.
1. Vacuum collector tube?
The collector is the heat collecting element of the system. Its function is equivalent to the electric heating tube of the electric water heater. Unlike electric water heaters and cgas water heater, solar collectors use radiant heat from the sun, so the heating time can only be when the sun is shining. “All-glass solar collector vacuum tubes are currently popular in the Chinese market. The structure is divided into outer tube, inner tube, selective absorption coating, getter, stainless steel clip, vacuum sandwich and other parts.
2. Insulated water tank
An insulated water tank is a container for storing hot water. Since solar water heaters can only work during the day and people usually use hot water at night, the hot water produced by the collector during the day must be stored in an insulated water tank. The volume per day is the total amount of hot water used at night.
3. Bracket
The solar water heater bracket is the supporting element of thesolar water tank and an important part of solar water heater.
4. Connecting pipes
The pipes that carry hot water from the collector to the insulated water tank and carry cold water from the insulated water tank to the Collectors are connected to the pipes to that the entire system forms a closed loop.
Use a drink can and spray it with black paint (also wrapped in a layer of black paper). Put it in the sun, it is the simplest and most primitive solar water heater.
Method 1: Use a drink can and spray it with black paint. Placed under the sun, it is the simplest and most primitive solar water heater.
Method 2: 1. Fill a plastic bottle (preferably a beverage bottle) with an appropriate amount of water. 2. Prepare some mirrors. 3. Place mirrors around the plastic bottle and place it on the flooreil. .According to the reflection principle, water can be heated.
Solar water heater is a heating device that converts solar energy into thermal energy. It can heat water from low temperature to high temperature to meet thermal needs. people in life and water production.
