1: How it works
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.
Each 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. Whether gas, electricity or oil is
used for water heating, every unit of energy recycled by GFX must be
multiplied by some large factor when estimating fuel-energy savings or
corresponding reductions in pollution. Since the EPA doesn’t offer
Energy Star labels for either DHR or water heating systems, it’s up to
consumers to cut waste and pollution from their water heaters.
Perhaps the most important and 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
Other ramifications of GFX are discussed by Editor J.D. Nisson in
"Extraordinary Water Heat Recovery Device" [December, 1996
"Energy Design Update" Newsletter]; including how GFX "gives
an electric water heater the capacity of a gas heater". In fact,
when tested with GFX, the first hour rating of two types of high
efficiency 50-gallon electric water heaters tripled to 180 gallons; more
than "double the capacity of typical 50-gallon gas heaters" --
with an energy factor rivaling that of a heat-pump, plus unsurpassed
reliability and quietness.
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.
All-copper, NSF/ANSI Std.-61 construction means GFX: (a) will not
poison your loved ones they way some uncertified Canaidan knockoffs
continue to do, (b) will last as long as your plumbing system and (c)
will pay for itself many times over. Safety is guaranteed by
U.L.-approved, NSF/ANSI Std.-61, double- wall-vented construction and
self-cleaning ensures maintenance-free operation at peak efficiency. The
falling-film heat exchanger models listed in Tables A & B offer ultra-high heat transfer coefficients
required for compact size and high capacity.
