Heat recovery from DHW Heater...

An immediate benefit to owners of all-electric homes is GFX's power-boost; enough to triple the shower-capacity of tank-type water heaters and halve the cost of a shower. For example, if GFX boosts cold water temperatures by 30 degrees, it's feeding back about 10 kW of power; more than enough to triple your family's showering-time and save 2 kW of energy per 12-minute shower. This means if you pay 8.5 cents to 17 cents per kWh for electricity and your yellow water heater sticker shows an efficiency rating (energy factor) of 85%, GFX could save you 20 cents to 40 cents per shower, depending upon where you live and type of showerhead installed.

GFX is an award-winning plumbing product developed under a U.S. Department of Energy Grant; engineered to feed back enormous amounts of energy carried down the drain -- energy equivalent to "2 billion gallons of oil" annually wasted in the U,S. alone according to their evaluation. Adding multi-housing, commercial, industrial, state and federal usage increases potential savings to over 7 billion equivalent gallons of oil per year. In fact, about a trillion kWh (= 3413 trillion Btu) go down America’s drains each year. One Btu is required to raise the temperature of a pound of water by one degree-F and there are 8.34 pounds in every gallon. Every unit of electrical energy delivered to millions of electric water heaters requires about 3.2 times as much fuel-energy be consumed at electric power plants. Millions of archaic gas and oil water heating systems are also very inefficient, as discussed in an A.D. Little Report for DOE & EEI. Consequently, far more than 3413 trillion Btu/yr go up smoke stacks used to produce heat or electricity for the billions of gallons of hot water Americans send down their drains.

According to U.S. EPA standards, if just 6 million electric water heating systems were to be upgraded by GFX, carbon dioxide emissions would drop by more that 20 million tons per year; the amount released by burning 1.8 billion gallons of oil.

Its less expensive than a complete solar system, no parts to break or ware out needing replacement, and the data speaks for itself. Soomething simple that works.
