Solar Water Heater Working Principle

Solar Water Heater Company in Malaysia

Solar Water Heaters

The solar water heater is a cost-efficient system for generating warm water for domestic usage. They can be utilized in every climate condition, and the fuel they utilize sunlight is free of cost! It can also provide up to 50 percent and 90 percent of the household’s warm water needs, all depending on your climate as well as the model of your solar water heater.

Solar water heater systems

There’re 2 main types of solar water systems available in the market. The main difference among those is how to water be heated is transformed among the collection of storage water heater and tank.

Passive water collection heaters

This solar water heater system relates the collection of cold water on a tank that’s mounted in the roof and heated through solar energy. They’re also energy savers as they don’t need the power to pump the water.  There’re 2 main circulation systems available for this:

  • Open/direct circuit system – the tanks are linked to allow following water from one to another tank. This system is fine for areas that don’t experience freezing weather conditions.
  • Closed-circuit/indirect system – it makes utilization of heating fluid, present together with the water in the tank, to move its heat to the water upon warming. This system is usually used in an area that experiences freezing or frosts conditions during the winter season, as the heating fluid also possesses ant-freezing properties. Such fluids include glycol water mixture and water.

To transfer the water, the passive system utilized either gravity fed and closed coupled flow. The gravity-fed system has a huge water collection tank located above the storage water heater in the room. Through natural gravitational force, the water is moved through pipes from the collection to the tanks and your taps.

For the closed coupled unit, the collection tank is situated under the solar water heat storage and through normal water pressure transport the water to the storage tank and your taps.

Active water collection heaters

This is a fine system if you’ve limited area in the roof or already a conventional water heater unit. The storage tank for this unit can be located on the ground or below the home, with the heater water from the tank pumped to the storage.

One main advantage of this system is that it can be set up by just changing your already present traditional hot water system to that of solar water heater systems. Though, energy is required to power the pump if you’ve an active solar water heater system.

The Way solar water heather Works

It comprises the storage tanks and solar collectors. The working procedure for these water heaters is quite smooth. The solar panels or collectors are installed on the roofs of the homes that collect the energy from the sun and move it to the pipes containing water and heating it in the working. The warm water is then stored in the solar water heater storage.

In the case of traditional water heaters, gas or electricity is needed to heat the water whereas the solar water units need none of these to start the process.

It’s mainly one of 2 types the active and passive water heaters. It can be utilized in any sort of climate including frosting conditions. These heaters utilized fluids and pipes to warm the water. The passive heater is also known as ICS.

Before selecting a solar water heater it’s vital to known the basic features of the water heater and which sort of heater is appropriate for your house. The geographical area should also be taking into account before installing a water heater unit. You will need to install solar collectors according to the space of your house as a huge house will need more solar collectors to heat the water and vice versa.

It can be bought via various online stores in Malaysia such as www.bwsmalaysia.com.my which offers a range of models at extremely affordable prices. You can simply select the right solar water heater and solar water filtration system that matches your needs as well as your budget. Although installment of the solar water heater is quite costly, it’s much more affordable compared to the gas or electric water heaters.

Basic benefits of Using Solar Water Heater

In comparison to the traditional water heaters, these are much more cost-efficient as it needs natural resources for heating purposes, i.e. the sun. Thereby most of the clients are cable to save the cost of gas and electricity bills.

The unit powered by the sun can be utilized to warm water in homes where there’s a shortage of gas and electricity supply. Yet another best benefit of using solar water heaters is that it’s eco-friendly. It’s doesn’t emit any sort of poisonous gas while working.

 Unlike traditional water heaters, these are more durable and last long longer.

Though, proper care and maintenance are needed to make sure efficient functioning of the solar water heaters. It’s best proffered to have an expert to install the water heaters in your house. Though, passive water systems need less maintenance, active water heating systems need maintenance for smooth and proper functioning. Due to its high efficiency as well as reliability, the solar water heater is used by millions all around the world.

However, REMEMBER…

Regardless of what solar water heaters you install, you have to position the solar collectors in the room at a perfect angle that has max exposure to the rays. One more key point to take into account is the size of the storage water heater that you need to cater to your home’s needs. Don’t buy something bigger than what you need.

Additional Info…

In the event of times, the sun is not shining, you’ve to purchase and install a booster to warm the water to prevent the temp in your solar heater from falling under a fixed value. Such boosters are powered by electricity, gas, diesel, or petrol. Though, boosters are energy guzzlers if they are used too often. Therefore, timers can be installed if you realize that your boosters system is being used too much.
