How Is Solar Water Heater Structured, Working?

Use this guide to understand how is solar water heater structured, working and the factors that affect it. The information is organized to make the topic easier to apply in practice.

Solar water heaters do not use electricity, effectively making extremely hot water, so they are trusted by many families, motels and hotels. The following article will help you understand more about the structure and operation principles of solar water heaters

Solar water heater also called Thai Yang is extremely simple design with the following three parts: vacuum heat absorption tube, hot water tank and rack. Each department will play a different role.

This is an extremely important part of solar water heaters. This unit will take up the role of absorption and heat transfer to heat the water.

The structure of vacuum heat absorption tube consists of 3 layers, in which the outer layer and the inner layer are made of materials capable of withstanding high impact. In the middle is the vacuum layer.

The body surface is coated with a special metal film with 3 layers of heat-resistant, heat-absorbing and heat-transfer layer to heat the water inside.

This is also one of three very important parts of water heaters. The insulation bottle will take over the function of storing heated water.

The thickly designed insulation bottle with 3 layers can withstand temperatures up to 160 degrees Celsius and has the ability to hold heat for up to 72 hours. The insulation bottle is usually made of SUS 304 stainless steel material which is both durable and ensures that the water in the bottle is always clean, anti-rust. In addition, the bottle has extremely good thermal insulation properties thanks to the complex insulation compound.

Shelf

The support unit is responsible for supporting heat-absorbing pipes and insulation vessels. Racks use stainless steel or stainless steel anti-rust material, sturdy, resistant to sun and rain.

Brackets are often designed to tilt so that solar water heaters can catch the sunlight at the best location, helping to absorb the heat. In addition, the rugged design supports mounting parts more tightly, ensuring safety during use.

Principle of operation of solar water heaters

The solar water heater operates based on natural thermal convection principle, when the sun is shining, the vacuum tubes without cold water will absorb heat and heat the water quickly without having to plug in the electricity as the machine Indirect hot water or direct water heater.

According to the principle of convection, hotter water tends to move up the water tank and cold water moves down below the vacuum tube to be heated. The process of making hot water will end when the water temperature in both the container and vacuum tube is equal.

Hopefully, the above article will help you better understand the structure and operation principles of solar water heaters. The machine works very simple but brings abundant source of hot water to use for many purposes: bathing, washing dishes, cooking rice, heating water.

Which solar water heater is the best

Solar water heaters are sold very much in the market, so it is difficult to know which products are best. If you have not selected any products, please refer to the following 3 suggestions:
