Solar water heaters are the latest and innovative technology in water heating systems installed in a home. This type of water heater is considered much more effective and efficient in terms of cost, performance, and energy savings, which is much more efficient than water heaters with electric and gas energy.
Water heaters with electric or gas power are very dependent on electricity and require large operating costs and gas which is a non-renewable natural resource. Meanwhile, solar water heaters utilize the energy of sunlight that is available in abundance. For several reasons, one of which is energy-saving, people are now starting to switch to choosing energy-friendly goods. If in the past people would tend to choose water heaters with electricity or gas, now they are considering installing solar panels on their roofs.
What Is A Solar Water Heater?
As the name implies, a solar water heater is a device that functions to heat water by using solar energy. This solar water heater is generally installed on the roof of the house.
Solar Water Heater Components
This solar water heater has components that are arranged in one device that making this device able to carry out its functions properly. The components that make up this solar water heater device are:
- Heat-absorbing collector
This component is a special area that is used as a medium to absorb solar energy. This component must have a high sensitivity to absorb heat, and also be very well insulated, so that it can always be more effective and efficient in carrying out its functions.
Two types of collectors can be applied. The first type is a flat collector in the form of a closed box with an insulating system made of glass or thick plastic. The plate owned by this collector is a broad plate with conducting material so that it can absorb heat perfectly.
While the second type of collector is a vacuum tube. This type of collector is equipped with two glass tubes that have an airtight cavity as an insulator which is very effective in keeping the heat in place and not spreading out. This vacuum tube collector is also considered to be more effective than flat collectors because it has very minimal heat loss.
- Storage tank
This component is a place that is used to hold water that has been heated by a heat-absorbing collector. Like a thermos that we use to store hot water, so that heat is not easily lost, this component must be coated with the best insulating layer.
Benefits Of Using A Solar Water Heater
Using a solar water heater is considered better than a water heating system that uses electricity or gas. Therefore, here are some benefits of using a solar water heater for your home.
One of the main reasons people use this solar water heater is that it is efficient. efficient, what is meant here is that solar panels can convert 80 percent of the radiation from sunlight into heat energy without using external fuel.
- Safe for the environment
The solar panel system is a system that applies go-green technology to create a safe environment. In addition, the solar system uses no fuel and even reaches zero emission levels.
- No Charge
This solar panel uses energy from the sun. This means we don’t have to pay a dime to the power grid to use electricity. Being a renewable energy source, these solar panels are free and available every day. What we need to do is figure out how to fine-tune our panels to optimize performance in cloudy weather.
- Save space
The solar panel system does not take up much space due to the installation of solar panels on the roof of the house.
- Easy maintenance
Solar water heaters do not require too much maintenance. This device only requires fairly simple maintenance. This is because these solar water heaters do not contain moving parts, and are made of materials that are not easily torn and broken which require regular attention and maintenance. Some manufacturers of solar water heaters even guarantee that this device will be able to carry out its functions for almost 20-25 years and can even work longer.
