Wollongong Water Tanks Provide a Full Range of Solar Products
Solar Hot Water Systems
Solar Power Systems
Wollongong Water tanks have extensive experience in providing solar hot water systems.
Closed Coupled Systems
A close coupled system is where the Storage Cylinder and the Solar Collectors are coupled together and the installation is on the roof.
Close Coupled Solar System use a thermo syphoning principle (i.e. hot water rises because it is less dense) to circulate the water through the Collectors and then to the Storage Cylinder without the need for a pump.
Supplementary heating from the electric element will generally turn on overnight to bring the water up to temperature if insufficient heat is available from the sun (such as during cloudy or rainy weather or during winter months).
Features
- Low heat loss due to greater insulation
- Wide range of Colorbond® colours available including Silver Prestige. Ask your Wollongong Water Tanks consultant for the full colour selection
- Supplied standard in Titanium colour
- Choice of two selective surface Collectors
Benefits
- Technically very efficient, economical to install and low maintenance
- No electricity required to operate pumps to recirculate the water through the panels
- 8 or 10 Riser tubes per panel for effective transfer of the solar energy to heat the water
- Available in both standard and frost tolerant ( FTC) versions
Solar Collectors
- Highly efficient all copper Collector with a selective surface maximising energy from the sun
- Full aluminium casing for corrosion resistance
- No recirculating pumps and pipe runs – reducing heat losses and improving running efficiencies
- Space saving in that it eliminates the need for a storage tank at ground level – ideal for courtyard homes or small blocks
Solar Split Systems
A split system is where the Storage Cylinder and the Solar Collectors are split and installed separately. A solar control unit ensures the water circulates via a pump between the Solar Collectors and the Storage Cylinder. This transfers heat from the Collectors to the water in the cylinder if enough heat is available from the sun. The electric element will boost the water stored in the Cylinder overnight if necessary.
Features
- Rinnai Prestige improved insulation level
- Choice of two selective surface Collectors
- Streamlined appearance – minimal impact on the aesthetics of your roofline with only the Collectors visible
Benefits
- Easy installation on roofs
- Split System Cylinder can be installed internally or externally
- Ideal system for construction of new homes and major renovations
- Split Systems do not require reinforcement of the roof structure, as the weight associated with water storage is at ground level
- Collectors and the Cylinder do not need to be installed at the same time
