How it works

Glass evacuated tubes are the key component of the evacuated tube heat pipe solar collectors. Each evacuated tube consists of two glass tubes. The outer tube is made of extremely strong transparent borosilicate glass that is able to resist impact from hail up to 25mm in diameter. The inner tube is also made of borosilicate glass, but coated with a special selective coating which features excellent solar heat absorption and minimal heat reflection properties. The air is withdrawn (evacuated) from the space between the two glass tubes to form a vacuum, which eliminates conductive and convective heat loss.

Energy absorbed to create solar hot water

Inside the glass evacuated tube described above a copper heat pipe is installed. The copper heat pipe transmits heat to its tip which is plugged into the collector’s heat transfer manifold.

As water runs through the manifold heat is transferred from the copper heat pipe to the water as shown in the diagram (right). The heat transfer manifold is housed in highly insulated aluminum housing.

Solar energy transferred through to copper header

This method of heat transfer is a thousand times more efficient than a solid copper rod. Heat is therefore very efficiently transferred from the glass evacuated tube to the water. Since no water is flowing through the collector tubes and the tubes are hermetically sealed it does not suffer from corrosion problems, as is the case with other types of solar collectors.

Unlike other types of solar collectors, evacuated solar collectors still provide excellent results on cloudy days. This is because the tubes are able to absorb the energy from infrared rays which can pass through clouds. Wind and low temperatures also have a minimal effect on the function of evacuated tubes when compared to flat plate solar collectors. This is due to the insulating properties of the vacuum in each tube.

Instantaneous Gas Boosted Solar Hot Water

Instanteous gas boosted solar hot water

The Instantaneous Gas system is supplied with either a S20 or S26 Solar Rated Instantaneous Booster Unit and either a Vitreous Enamel or Stainless Steel Storage Tank.

With the Gas Instantaneous solution you only heat water as you use it. An extremely efficient way of producing hot water. These systems operate just as your normal gas hot water system would, without the energy cost.

Electric Boosted Solar Hot Water


Electric boosted solar hot water

The Electric Boosted Hot Water System is supplied with either a Vitreous Enamel or Stainless Steel Electric Boosted Tank that will operate the same as a standard non-solar electric hot water system.

It is connected to off-peak electricity or put onto a timer to take it off automatic boosting. The thermostat will read the water temperature once a day to heat your water to 60°C to complement the energy harvested from the sun.
