(a) Efficiency vs. Flow Rate

(b) Computer Model Comparison

Fig. 1(a): Equal-Flow efficiency curves for LC-GFXs 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 DOE computer models and inaccurate 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. Click on Fig. 2 below to see certified performance of a Watercycles S3-58-LC GFX measured and modeled by the Saskatchewan Research Council (SRC).

Table 1 in Rocky Mountain Institutes 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 Rinnais 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, a modern LC-GFX meets plumbing codes because their coils are self-venting because they are not dip-soldered. (Discontinued GFXs have about 24 turns/ft.)

Whats the LC-Advantage?

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

NOTE: NRCans 2007 Report is a fraud; as may be verified by comparing Table 3 in their 2006 Report to graphs on pg. 20 in their 2007 Report & Performance Curves for any 3 or 4 LC-GFX.

Why Pay More? GFXs sold by Sears, Home Depot and others cost about 35-40% more, save less energy than a comparable LC-GFX, and are made with stolen trade secrets! If you buy a single-coil GFX, a counterfeit like that shown @ gfxtechnology.com/Exporting-America.pdf will probably arrive until a Canadian Court grants justice long denied in this Pending Infringement Lawsuit.

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 GFXs 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 https://gfxtechnology.com/EnStarCom.pdf.
