If your home is in a temperate or tropical location, which is not subject to frost, and you have good quality drinking water, then the GTD Series 2 system is ideal. This modern designed ground mounted Solar Hot Water System called the GTD (Ground Tank Direct) system transfers the suns energy directly into the water through the solar collectors; this is described as a "direct" system. The hot water is then automatically conveyed from the collectors to the storage tank, this process continues whilst the sun is shining, giving you free hot water from the sun.

• Boosters are built in electric.

For areas which experience frost or snow and perhaps have less than reliable water quality, the GTS Series 2 system is the only choice. Being an "indirect" system the water is heated indirectly via an in-tank heat exchanger using a mixture of Glycol to transfer the collected heat from the collectors.

• Systems come with gas boosters to ensure continious hot water supply.
