Should I use a solar water heater?

Solar water heater is no stranger to many people, it is a device that heats water naturally without using the national grid. Solar water heater system can be installed anywhere for households and businesses to use, while making the most of the energy from sunlight and saving electricity consumption costs. . However, this device is still not completely popular, there are still many questions about whether to use a solar water heater or not? The following article will help you find the answer.

Solar water heater is an electrical device that uses energy from sunlight to heat the water inside the tank. The collector is responsible for collecting heat from sunlight to heat the water up to. 98 degrees Celsius. The degree of water heating depends on the intensity of sunlight and how to install the water heater to absorb the maximum sunlight.

Solar water heater works on the principle of natural heat convection. Accordingly, the device will take advantage of the ability to absorb solar energy through tempered glass, with a lenticular structure to increase heat absorption efficiency. In addition, the bottom layer of insulation increases the efficiency of water heating.

Solar energy is absorbed at the surface of the device to heat the water, due to thermal convection, the water in the insulator will increase, this process continues until the temperature in the tank equals the temperature. of water at the absorber.

Using hot water is a necessity for many households, so the use of solar water heaters is necessary, they save time heating water faster. In addition, let's see a few reasons to use a solar water heater below:

The system of getting electricity from solar energy is completely natural, so there is no cost for electricity consumption. However, you will have to pay initial investment costs for equipment installation.

Solar water heater is equipped with a flat plate protected by a layer of high-grade tempered glass for high durability, excellent heating efficiency. At the same time, this machine also has a heat-absorbing tube with a tight design, minimizing the accumulation of dirt or algae in the tube, ensuring hygiene and safety for consumers' health. And of course, the use of solar energy is extremely safe, not afraid of electric shock, not afraid of fire and explosion, very suitable for modern urban life.

The use of environmentally friendly devices has become a trend in a modern and civilized lifestyle. Therefore, solar water heaters are a safe solution for the environment, both taking advantage of abundant solar energy, and minimizing the use of electrical energy, without creating harmful CO2 emissions. pollute the environment.

Although you have to spend a large amount compared to buying a conventional water heater, after only about 2 years of use you will find that the solar water heater is actually the problem of maximum savings for the family. You also don't need to worry about paying for electricity every month. High durability, can be used for a long time is a great advantage of solar water heaters.

Solar water heater allows you to use it even when the power is out, something that any other type of water heater can never do. Moreover, the water is heated continuously during the day by the machine and the thermos flask has the ability to keep hot for up to 72 hours so you can use it for bathing, washing dishes, cooking... very convenient for family activities.

Solar water heaters have many advantages when used, so many people have bought this device to equip their families. However, choosing the right type of water heater is difficult for many people. Currently, there are 3 common types: flat plate type, vacuum type and oil tube type. Each type has different characteristics for customers to choose from. Here is the experience of choosing the most efficient and best energy water heater today:

This is the most common type of water heater used today. With the advantages of high heat absorption capacity, fast hot water supply, easy installation and operation, along with low price, it attracts many people's attention. However, this type has the disadvantage that the vacuum tube is prone to deposits and moss growth after a long time of use. Therefore, we need to regularly clean to ensure that we have clean water to use.

This type of machine is quite similar to a vacuum water heater. They have the advantage of being able to work even in the absence of sunlight. The ability to create hot water quickly, without moss or water residue, long life. The machine is also more expensive than the vacuum machine.

This is the most modern technology solar water heater today. They are completely different from oil and vacuum tubes. With the advantage that it can be installed at any position on the roof, it can work even in cold weather with a quick hot water production rate. No dirt or moss when used for a long time. However, this type of machine has a very high cost, operates on electricity, so when the power goes out, there will be no hot water to use.

In general, using a solar water heater is a new step in using natural electricity, helping to save electricity consumption costs and reduce environmental pollution. Each type of solar water heater has different advantages and disadvantages, but they all work to provide safe hot water, absolutely without causing electric shock. With simple installation and maintenance, this is an essential device for every family.
