Introduction to Solar water heater
There is a widespread use of solar energy. It is viewed as the best source of alternative energy and enjoys a wide range of applications.
Among the many uses of solar energy is water heating. This energy source is used for heating waters for both domestic and industrial purposes.
The heating is usually done by solar water heater. They are able to convert the energy from the sun into heat energy.
Are you planning to buy solar water heater system? Read on as I reveal everything that you should know about this water heating device.
What is Solar Water Heater?
Simply defined, a solar water heater is a device that uses the heat energy from the sun to heat water.
It provides the most economical way of heating water.
Take note that a solar water heater is not the same as a solar panel. The purpose of the panel is to use energy from the sun to generate electricity. On the other hand, the purpose of the heater is one. To heat water.
This means that the two systems are different despite the fact that both are depending on solar.
How Does a Solar Water Heater Work?
A solar water heater has two main parts. These are the solar collector and the storage tank. So, the working principle of any solar water heating system will revolve around these two parts.
In short, at any given time, there will be an exchange of water between the collector and the tank
Although there are different types of solar water heaters, all of them are somehow connected by a common solar water heater working principle.
In any solar water heater, the water is heated by the thermal energy that is taped directly from the sun.
The collectors absorb the heat energy from the sun.
Hot water which has a lower density will move upwards while the denser cold water will move downwards.
The collectors can be arranged in series or parallel. This is done to increase the quantity of water that is heated at any given time.
The tank that stores the hot water is insulated to prevent any loss of heat.
The movement of water can be aided by a circulation pump or it can be through gravity.
Types of Solar Water Heater
Solar water heaters are divided into two broad categories. These are; collector-based and heat pumps. This can also be passive solar water heater vs active solar water heater
- Collector based solar water heaters
The collector-based solar water heaters are
-Flat plate collector
-Evacuated tube collector
-Heat pump solar water heaters
-Flat plate collectors
These are the types of solar water heating systems that are mainly used for domestic use. A typical flat plate collector comprises of an insulated box and a dark absorber plate.
The insulation prevents heat from escaping from the plate. The absorber is designed to tap maximum heat that will be responsible for raising the temperature of the water.
-Evacuated tube collector
These collectors are characterized by rows of transparent glass tubes which are positioned to be in parallel to each other.
Each tube has an absorber which absorbs the heat from sun. The absorber can be a metal which has a fin designed to absorb solar energy.
Integral Collector Storage Systems
These ones are usually referred to as batch solar water heating systems. In terms of this solar water heater design, this one features a glazed box with several tubes.
The collector receives water then preheats it. This water is then transferred to the back up heating unit.
This type of solar water heater is usually used in areas that experience prolonged temperatures.
2. Heat pump systems
Heat pump solar water heaters have the same working mechanism as air conditioners. The wok by collecting the solar heat from the surrounding air and direct it to the target zone.
This means that they do not have the solar collectors to do the heating job.
The heat pump systems are also referred to as active solar water heaters. This is because they continuosly absorb the heat.
The pumps circulate operate by circulating a non-freeze heat fluid through the heat exchanger. The exchanger will then heat up the water.
These pumps are mainly used in extremely cold regions that are prone to freezing conditions.
So which is the best type of solar water heater?
Flat plate collector (FPC) are known to be more durable than the evacuated tube collector (ETC) whose tube is made of glass material.
In terms of the cost, ETC solar heater are cheaper than the flat plate collector systems. They are also more suitable for cold regions or during days when there is a limited exposure to sunlight.
Flat plate collectors are also more suitable for the usage of hard water or water that has high chlorine content.
