Technical Data

In the harsh South African climate, the Edwards LX Series system is the only choice. It uses the highly efficient heat transferring properties of a special anti-freeze fluid to transfer the energy to heat the water indirectly.

With an 'indirect system' water does not pass through the collector panels, insted the anti-freeze mixture is ciruclated from the collectors through a jacket which is wrapped around the storage tank, transferrinf the heat into the water.

The benefit of the 'indirect' heat exchange process is that the system can be used confidently in frost areas, without risking damage to the system; it offers protection against freeze damage in conditions of up to minus 8 degrees Celsius.

The storage cylinders for all Edwards roof-mounted solar water heaters are constructed from long life stainless steel. Stainless steel acts as a natural barrier to corrosion. Therefore, Edwards stainless steel systems do not require a sacrifical node and are virtually maintenance free.

The new modern design of the LX Series system was designed and manufacturered in Austrailia for a range of conditions. Not only will it compliment any home's roof and save you immediately on your home's energy costs, it offers you peace of mind knowing it has been developed to last for years.
