When choosing a solar hot water system, many consumers do not realise that these systems can be completely dependent on location and hot water needs – there is no one-fits-all model. The basic layout of the heaters remains the same, with roof-mounted storage cylinders containing the water, although the internal materials can be completely different.The solar hot water system you choose is dependent on your water quality, the pitch of your roof and the climate in which you live. Considering the highly diverse climates found in Australia, in this blog we’re focusing on illustrating how different types of solar heaters function.If you don’t live in an area with abundant sun, options are available to compensate for these low sunlight areas. To compensate, solar heaters can be fitted with an in-tank electric booster element or an in-line gas continuous flow booster. These additions allow for you to easily compensate for when you don’t have the necessary solar gain to heat your water.Solar Hot Water for Different ClimatesDepending on your climate, solar heaters can be radically different – components found in some models are completely absent in others. For areas in Australia with a tropical climate and good quality drinking water, solar heaters that operate on the thermosiphon principle (when water is heated it rises) are recommended. This process ensures that water is directly heated as it passes through the collectors, after which it is automatically circulated back into the storage tank.For areas with a frostier climate, solar heaters are available with a special anti-freeze fluid used to transfer absorbed energy to indirectly heat the water. These indirect systems circulate the anti-freeze mixture (glycol) through a heat exchanger and transfer the heat into the water. This heat exchange is optimum in colder and frostier environments without risk of system damage possible due to frost.Users looking for the best solar heaters on the market should look to high-performance heating systems. These systems utilise the most advanced heat transferring technologies in their solar collectors to gather as much of the sun’s energy as possible, and use titanium coated copper solar absorber plate to ensure greater solar performance overall.
