(a) Efficiency vs. Flow Rate

(b) Computer Model Comparison

Fig. 1(a): Equal-Flow efficiency curves for LC-GFX’s having 3” copper drainpipes 20” to 80” long; based computer models developed in 1986 for U.S. DOE. (Left clicking on graph opens curves for 3” & 4” models.) Fig. 1(b) compares results predicted by sophisticated DOE computer models and simple-minded equations by Natural Resources Canada (NRCan), which predict abnormally high efficiency values at low flow rates (where falling films collapse); abnormally low efficiency values at high flow rates.

Table 1 in Rocky Mountain Institute’s Home Energy Brief #5 shows improved savings possible when a GFX is combined with several types of “green” water heaters, including on-demand (tankless) & heat pump water heaters. Use Rinnai’s Tankless Savings Calculator to compare savings for large & small families.

What is a Lo-Copper GFX?

A Lo-Copper (“LC”) GFX is a gravity film heat exchanger having a flattened coil with about 15 turns/ft; like the GFX in Fig. 1 of this 1986 DOE Report. Unlike the 1986 version, modern LC-GFX’s meet plumbing codes because their coils are not dip-soldered and are self-venting. (Discontinued GFX’s have about 24 turns/ft.)

What’s the LC-Advantage?

Based on 3 Canadian reports (1998, 2002, 2006) and refined computer models used for Figs. 1(a) & (b), LC-GFX’s offer a higher Savings to Investment Ratio (SIR) and faster payback compared to competing GFX-models evaluated in NRCan’s in 2006 Report.

NOTE: NRCan’s 2nd Report is a fraud; seen by comparing Table 3 in their 2006 Report to graphs on pg. 20 in their 2007 Report & Performance Curves for 3” & 4” LC-models.

Why Pay More? GFX’s sold by Sears & Home Depot cost about 35-40% more, save less energy than LC-GFX’s, but are made with stolen trade secrets! If you buy a single-coil GFX from Sears or Home Depot, a GFX like the one shown @ www.gfxtechnology.com/Exporting-America.pdf will probably arrive until a Canadian Court grants justice; long denied in this Pending Infringement Lawsuit.

Fig. 2: Model S3-58-LC shown is equivalent to a pair of 30” G3-30-LC’s having their drainpipes connected in series; coils plumbed in parallel. “S” models offer nearly an 8:1 reduction in pressure drop, with slightly less Efficiency.

ENERGY STAR HOAX

     LEED certified buildings command a hefty premium compared to ENERGY STAR buildings, according to recent studies by the New Buildings Institute (“NBI”) and the CoStar Group. The latter analyzed more than 1,300 LEED Certified & Energy Star rated buildings, representing 351 million square feet, and found LEED buildings command premiums of $11.24 per square foot, compared to $2.38 for ENERGY STAR rated buildings. "As a result ENERGY STAR buildings are selling for an average of $61 per square foot more than their standard buildings, while LEED certified structures earn a remarkable $171 more per square foot." For obvious reasons, electric & gas utilities and politicians in their pockets promote ENERGY STAR over LEED. To understand why, turn back the clock to 1996 -- to a Conference whereat the audience was informed that DOE usurped the EPA's ENERGY STAR Program by taking over its Appliance segment then quickly denied an ENERGY STAR Label for LEED Certified GFX’s and eliminated them from new construction. To estimate how much DOE degraded ENERGY STAR by failing to grant labels for water heaters, GFX and other big energy savers, see http://gfxtechnology.com/EnStarCom.pdf.
