The banning of electric storage hot water systems throughout Australia during 2012 has made needing to know what systems are available, and which will best suit your home, more important than ever.

Every day your home or business keeps using that old electric storage hot water system, is another day that you don't benefit from the lower running costs, improved property value, and lower CO2 emissions, provided by a well designed and installed RO water system. Subjects that I'm sure you will agree are becoming more and more important to us all.

Types of RO water system:

RO water system come in two main configurations, Close Coupled (tank on roof) or Split Systems (tank on the ground). I shall also discuss Heat Pumps which are seen by many as solar based technology.

Configuration Type 1

Close Coupled Systems

These offer lower running costs (excluding boosting) as they don't require any electricity to move the water from the collector to the storage tank, taking advantage of natural "thermosiphoning". The trade-off is a bulker unit with higher system weight on the roof. For example, a 300L storage tank holds 300kg of water + tank and collector weight.

Configuration Type 2:

Split Systems

Split Systems have the collector on the roof and the storage tank located somewhere else- normally on the ground. Split Systems require the use of solar pumps and controllers to monitor temperatures, and move water from the collector(s) to the storage tank. This does involve small amounts of energy being used -- normally around 28-60 watts per hour for up to 8+ hours a day.

Collector Type 1:

Flat plates use a large collector surface to pick up the Sun's heat with water pipes embedded in the collector to transfer heat. The collector surface is protected by a sheet of glass or plastic that generally offers little to no insulation.

Collector Type 2

Evacuated tubes

Evacuated tubes take advantage of the natural insulation properties of a vacuum, which allows heat

to enter the glass tube, but then doesn't allow that heat to escape back into the atmosphere.

The use of a vacuum also gives evacuated tubes natural frost protection, with no need for antifreeze additives like glycol that can also reduce performance by up to 10%, and create ongoing maintenance needs.
