The GFX Drainwater Heat Recovery Systems is a new invention that reclaims tremendous amounts of heat energy that normally runs down your drain. The GFX acts as a "comfort booster" that increasing the ability of your existing water heater to meet your hot water requirements without increasing the size of your existing hot water heater. It's inexpensive, installs easily and pays for itself in endless warm showers and saved energy.
