This makes us the number one choice for the best deals in purchase and installation of solar hot water systems in Sydney and New South Wales as a whole.


Solar Hot Water System Sydney – Types

Close couple systems: they are known to lower the overall running costs due to the fact that no electricity is required to move water to the storage tank from the collector. Instead, a process called thermo-siphoning is used. For these advantages, you get to have a unit that is bulkier and weighs more on your roof.

Split systems: these types of systems usually have the collector installed on the roof and the storage tank located elsewhere. They require solar pumps as well as controllers for monitoring temperatures and moving water from collector to storage tank. The amount of energy used is usually small.


Solar systems can also be categorized by the type of collector used. There are three main types of collectors used, which are:

Flat plates: This type of collectors have been used in Australia since 1953 when they were first designed, to date. They use a collector surface that covers a large area to absorb the heat from the sun and transfer this heat to water in pipes embedded within it. The surface of the collector has a plastic or glass sheet for protection.

Evacuated tubes: They were first developed in Australia in the mid- 1970s. They were however, not popular until 25 years later when they became available widely in Australia. This type of tubes provide the best performance/ square meter in comparison to all the collectors available in the Sydney market.

The evacuated tubes make use of the insulation properties that a vacuum has by allowing heat to enter into the glass tube and preventing it from escaping back into the atmosphere. Vacuum also provides a natural protection from frost, making the use of antifreeze additives unnecessary. The antifreeze additives reduces the performance as well as increase maintenance costs thus, eliminating their need is advantageous.

Some of the other advantages that come with evacuated tubes include;

  • They have round tubes which allows for passive tracking of the sun leading to a greater performance.
  • They have less weight thus minimize the pressure exerted on the roof.
  • They have a modern and stylish design. This ensures that you do not compromise on the aesthetic appearance of your home.


Considerations when installing solar water heaters

Roof orientation: solar hot water performance can greatly be affected by the solar orientation. The ideal orientation in the southern hemisphere is due north, and due south for the northern hemisphere. Try ensuring that the system is installed in the right orientation.

Roof pitch: the roof pitch also affects the system performance of solar hot water systems. This should be considered during the design of the solar system before installation. The higher the roof pitch, the better the performance during winter seasons. Lower roof pitch on the other hand increases the performance during summer. If the roof has a pitch lower than 20 degrees, the system should be placed on a frame in order to optimize the angle.

Shading: shading of a solar hot water system really reduces the performance of the system, when compounded for the whole year. Try getting the unit installed where there is very little or no shading. Some of the major sources of shade include trees, buildings and valleys. These factors when unavoidable, will influence the type of system to be installed.

Frost: there are different types of technology employed for the different types of solar hot water systems. For people living in frost-prone areas, choose a technology that will handle that type of condition in the best way.

Backup options: it is always advisable to have some form of backup for your solar hot water system. The reason for this is because there are times of the year when even the most effective systems cannot provide sufficient temperature levels. The most common backup boosters are gas and electric element.

Along with solar hot water systems in sydney we also provide solar panels, guttering, roof restoration and roller shutters for you to get multiple benefits for buying multiple products from Impulse.
