Solar Hot Water Systems (Electric and Gas Boost)

Close 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.

Rinnai Close Coupled Solar systems use a thermo-siphoning 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 or instantaneous gas will 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 through greater insulation
• Supplied standard in Titanium colour
• Choice of two selective surface collectors

Benefits:

• Technically very efficient, economical to install and low maintenance
• No recirculating pumps and pipe runs – reducing heat loss and improving running efficiencies
• No electricity required to operate pumps to recirculate the water through the panels
• Space-saving in that it eliminates the need for a storage tank at ground level (ideal for courtyard homes or small blocks)

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 collector and the storage cylinder. This transfers heat from the collectors to the water if enough heat is available from the Sun. The electric element or continuous flow gas booster will bring the water temperature up if necessary.

Features:

• Rinnai Prestige improved tank insulation levels
• Streamlined appearance – minimal impact on the aesthetics of your roofline with only the collectors visible
• Choice of two selective surface collectors

Benefits:

• Easy installation on roofs
• Split systems do not require reinforcement of the roof structure as the weight of water storage is at ground level
• Split system cylinders do not to be installed at the same time
• Ideal system for construction of new homes and major renovations

Solar Collectors

Excelsior Solar Collectors

• Highly efficient all-copper collector with a selective surface maximising energy from the Sun
• Full aluminium fin solar absorber to maximise efficiency
• 8 riser tubes per panel for effective transfer of solar energy to the water
• Full aluminium casing for corrosion resistance
• Equinox Collector has added feature of Frost Protection

Gas Booster

The gas booster is usually installed on a wall near the cylinder and will not activate until the hot water is required.

There may be some periods when the Sun can’t provide for all of your hot water needs (could be rainy weather, or it could be that you have visitors). To cover this situation, the gas booster will come on and bring your water up to temperature.

Regardless of whether you hot water is use in the mornings or evenings, gas boosting is the most efficient, convenient and cost-effective boost option. Gas boosters operate only on demand and have the additional benefit of never running out of hot water.
