So, how does solar water heater work, what are the advantages and disadvantages, including what types, the price? Let's find out with GikaSun through the information below to make the right choice.

What is the solar water heater? How does it work?

Solar water heater is a device that uses energy from sunlight to heat water for domestic needs.

Solar water heaters operate on the principle of thermal convection, turning solar energy into heat energy. The energy from the sun is absorbed through collecting plates or vacuum tubes. This energy is converted into heat energy and heated water.

Advantages and disadvantages of solar water heaters?

Advantages

Extremely safe due to the use of natural energy is the sunshine.
No electricity costs during use.
Low maintenance costs, less petty damage.
Use when the power is out, suitable for places where electricity is flickering, power is weak, frequent power outages.
Provide hot water for the entire house, regardless of the number of bathrooms.
Environmental friendliness

Disadvantages

The price is quite high compared to other types of electric water heaters.

Large tank capacity (usually the smallest is 140 liters) should be able to use one bottle for many bathrooms at the same time, meeting the needs of large use.

Types of solar water heaters:

Currently, GikaSun is providing 2 types of solar water heaters: flat plates and vacuum tube.

Flat plate solar water heater:

Under sunshine, the heat absorber absorbs sunlight, converting it into heat. This heat heats up the water in the heat-absorbing pad. According to the convection principle, hot water with smaller density will move upwards, cold water will sink below. Just do so alternately until the water temperature in both the tank and the plate absorb the heat equally, the process ends.

Vacuum tube solar water heater

Water will go into the vacuum glass tubes. When the sun is shining, the materials absorb the heat on the outside of the glass tube, causing the glass to heat up to transfer the water's temperature inside the tube.

According to the convection principle, hotter water tends to move up the tank and cold water moves down the vacuum tube to be heated. Keep rotating until the water temperature in both the tank and the vacuum tube is equal, the process ends.
