GFX (Gravity-Film Heat Exchanger)

Tired of running of hot water in the shower? A GFX system can abolish this problem, but more importantly alter water and energy consumption. The GFX is coiled copper tubing that connects to the drain of a shower or other behind the wall. As hot water drains from the shower during use it is used to preheat the cold water in the line that has been diverted to the GFX. This creates a much reduced demand for water to be heated and water to flow from hot water side. The result: less water and energy use!
