Testimonials & Comments
Residential
Matt from
Vermont “My testimonial would be that my GFX
allows me to increase the capacity of my 40 gal. LP-fired water heater which
is being used to provide heat in a 2000 sq. ft. home and domestic hot water for
a family of 4. Cool, huh? –Matt.” Ohio Homeowner “I enjoy it. Our water heating costs
have gone down by one-third.” Robert from
Virginia “Is
there some way I can induce a new home builder to include this in the
construction of my new home?” Comment by Many Why isn’t GFX required in all new
construction? Marilyn from
Virginia “We have had GFX installed in our house
for several years and we are delighted with its performance. Prior to its
installation we had a little less than 30 minutes of hot shower time from our
50- gallon electric hot water heater. After the installation we increased our
hot shower time to more than double. As a family of four, you can imagine the
impact. We never run out of hot water even if everyone takes back-to-back
showers. As an added bonus, there are energy savings as well. Anyone who uses
hot water should have GFX installed.” Dianne Falk From
Virginia “The Faulk’s GFX was installed on
12/10/97 and was to be turned to the off position for the first three weeks.
On 12/23/97 Diane Faulk called to see if I could turn the GFX on since she
was having 6 relatives stay with her over the holidays. She expressed to me
that having it on would give it a true test of how effective it could be with
recovery time. At times there would be 6 or 7 showers all in succession. I
agreed that it would benefit everyone to put it through a tough test. I went
out on 12/ 23/97 and turned it to the on position. Diane was real excited to
see how it was going to work. On 01/5/98 I returned to take readings and
talked with Bruce Faulk about how it worked. He was overwhelmed on how it
performed and said he would recommend it to anyone. The other customers are
saying the same things also, including myself. It does make a big
difference.” ... “The benefits are endless.” Bruce Falk From
Virginia
(February 12,
2004) “I would
like to strongly recommend GFX technology to any homeowner interested in
prolonging the life of their hot water heater and ensuring sufficient hot
water in any situation. … My hot water heater is now almost 20 years
old. I know the reason it has lasted
so long is due to GFX. The ability to
recirculate hot water has meant the heating element does not need to work as
hard. I have done nothing special,
other than to have this technology installed. My neighbors have been forced to change numerous heaters, yet I
save money, not only on heating, but also on not having to purchase new
equipment. …I have also been extremely pleased with the amount of hot water this
device provides. On many occasions, I
have had guests and family stay at my home.
No matter how many showers need to be taken, we never run out of hot
water. What a great invention!
Everyone should have one of these. It
saves money, it prolongs the life of equipment, it provides fast and
sufficient hot water, and helps the environment by using less
electricity. It has operated for over
7 years without a service call. I
urge everyone to get GFX.” Joanne from Long
Island, NY “GFX was installed in September of 1998
and to my surprise I received a credit of $279 on my oil-company budget which
ran from June ’98 to May ’99. We had a mild winter, which might account for
some of the savings, but there are other benefits we continue to enjoy. After
the installation of GFX, we were able to lower water heater temperature by 30
degrees to a much more comfortable temperature - no more burnt hands when
washing dishes …” New Zealand Hotel Manager“I would like to take this opportunity
to express my complete satisfaction with the installation of the GFX water to
water heat exchanger at the Wellington City YHA during November 1997 and the
additional units installed during September 1998. The initial trial unit of
an “S” Model GFX was installed on a common waste from 6 showers using 1110
liters of hot water per day. The data logged results showed a maximum
temperature difference of 18 degrees Celsius [32.4 F] and an average of 14
degrees [25.2 F] which is truly outstanding. Translated into dollar savings,
the single unit produced annual energy savings of $397.78 and an additional
annual demand savings of $241.68. The total savings each year is therefore
$639.46 and the payback was 1.12 years or 1.687 years including installation.
Energy is my second biggest cost in running the hostel after labour costs and
a payback of this magnitude is terrific! Last month ECOsystems installed an
additional 4 GFX and I am already impressed with the results. Results from
the before and after logging showed that, over a period of time where the
occupancy was the same the water usage actually up by 7%, the cylinders were
heating 24% less! I am convinced the GFX water to water heat exchangers are
an exceptionally economical energy saving device and am happy to recommend
them to anyone.” (See www.gfxtechnology.com/hotel.html) |
Jim from New Hampshire “I
installed one of your GFX devices last year during a remodel and it functions
wonderfully. We never run out of hot water. We have six children (three
teenage boys) so the shower demand can be quite high. I noticed another
benefit. I plumbed the heat-exchanger
water to the whole second floor for the sake of simplicity and this summer I
noticed that the toilet tank does not sweat.
Previous years the tank would leave puddles on the floor when the
weather is humid but this no longer happens because the water entering the
tank is not as cold. Thanks for a great product.” (7/03)
The Chereks
from Wisconsin We (family of 6) have installed a S3-60 for over a year
and are enjoying lower energy costs at a time when natural gas prices are
continuously sky rocketing - Thank You! Our natural gas consumption was
literally cut in half - that's with three girls (long showers) in the house.
When may this GFX-STAR technology be available and how much will it cost? Any
information would be greatly appreciated! (7/05) Commercial & Industrial
Commercial
Kitchens & Bakeries “Getting very close
to the 70% recovery advertised for the commercial GFX drain heat recovery
system”; says engineer Ray Goodpastor owner of Ray’s Service Co. in Seattle,
WA. Coin-Op Laundry
Manager from New Hampshire “GFX is zero
maintenance, we are saving about half of the water heating costs. It works so
well, I put one in at home and our propane bill is half” .... “I would have
paid nearly as much for another water heater as I spent on the GFX system,
but this saves me money every month, instead of costing more.”; says Ed Zuk
owner of Littleton Easy Wash in Littleton, NH. (Ed can be reached at
603-444-6797) Engineer from
Missouri (7/02) “We have used
plate and frame, and shell and tube heat exchangers in our processing
operation. These were high maintenance, plugging up constantly. We switched
to GFX units to resolve the plugging problems. They work! Our water heating
system no longer has any trouble keeping up with demand. The GFX units have
never plugged. The GFXs have been in for over 11/2 years; they are doing so
well I’ve Forgotten about them.”; says Jason Blankenship, Director of
Engineering Meramec Group, Inc.; Missouri, USA; manufacturer of molded
Polyurethane products. (Meramec uses flight-type dishwashers in the
application discussed @ www.gfxtechnology.com/dish.html.
(Jason is willing to talk to other engineers and can be reached at
573-468-3101 ext. 293) Engineer from
California “GFX is very
functional, you can sure tell the difference.”; says Rick Stover and engineer
with Energy Recovery, Inc. in Oakland, CA. Roto-Rooter
Manager from Ohio “I have had my
GFX unit installed for over a year. It has exceeded my expectations as to how
much heat it would recover. During the winter the incoming water temperature
is 48 degrees, the GFX unit I installed raises the incoming water to 88
degrees. The net result is my hot water expense has reduced from $22.00 per
month to $12.00 per month. I installed the model S3-60, I piped it direct to
the water heater…. feel free to use me as a testimonial on this product.”;
says John Winthur, Manager, Roto-Rooter Corp. Utility Manager
from Minnesota “The
preliminary results on our field study are very impressive.” Minnesota
Power’s Dean Talbott said he was seeing 35 to 40% less total water heating
energy on the first round of comparisons.
Note: Minnesota Power offers a $100 Rebate for GFX in
their Triple-E Program. One of their customers said: “It’s fool proof... The
GFX is a no-brainer.” Dan from Seattle “I normally don't "advertise" something unless I
*really* believe in it. I don't (and won't) make any money from sales of
this.... Ok, when I first found out about the "GFX Drainwater Heat
Recovery System". I thought that it was a good idea, and got a brochure
to read up on it. I found their sales office on the Internet http://www.gfxtechnology.com. What
this device does is to take the heat from the wastewater (usually the shower)
and use it to pre-heat the water going into the hot water tank. It does not
use any electricity. I was a little skeptical about how long the payoff would
be. After putting off getting one for a *LONG* time, I finally got
one. Shortly after, I installed the unit. We needed an expansion tank
for our hot water tank, so I added one at the same time. Due to the expansion
tank, my cost to install the system is a little higher than most. I did
the installation myself. We have an electric water heater. We get our
electric bill every other month. I recently received my first electrical bill
after installing the unit. Now we've been trying to save on
electricity, but read between the lines on this one. The billing cycle
was from April-May. Our house was electrically heated. Last year (late
summer) we switched to propane heat. During the summer we turn off the
heat (Unfortunately I don't remember exactly when I turned off the heat
last year). The least amount of electricity used in the previous year was
from June to July of last year. This billing cycle we had use of this device
for about 6 of the 8-week billing cycle. Final results:
I was told that this device had a 5-6 year payoff. At
this rate, I expect (even with the extras that I purchased) to have a payoff
in 6-9 months! I am talking about a savings of $50-$70 per MONTH. You are
welcome to forward this email to someone that might want to make use of
this type of savings. Would you want to save about $500 per
year? (more/less depending on how it is hooked up and how many
people are in the house)” (6/03) |
Critical Review by
Ned Nissan, Editor
) Here is a product that will
challenge our resident skeptics.
) Not only does it save 30%-50%
of a home’s total water heating energy consumption, it also effectively triples
the heating capacity of the water heater.
) Still reading?
) Developed over the past 10
years by inventor Carmine Vasile, CEO of Water Film Energy Inc., the GFX file
has been on my desk for over a year in the pile marked Amore data needed.
) Although the engineering
principles seemed sound, there was no good documentation of actual performance
to support the inventor’s fantastic claims. Until now.
) Virginia Power sponsored an extensive series of tests at Old
Dominion University that confirm Vasile’s performance figures. (www.gfxtechnology.com/tests.html)
) In fact, the final report
indicates that the GFX can match or exceed the performance of an add-on heat
pump water heater at a fraction of the installed cost.
) The Old Dominion GFX study
was part of a larger project to evaluate several electric water heating
technologies, including heat pump water heaters.
) When the results for the GFX
are compared to those for heat pump water heaters, the GFX looks better.
) For the three electric
heaters tested, the measured energy factor was higher with the GFX than with an
add-on heat pump water heater.
) Nonetheless, given the much
lower cost of the GFX, it appears to be a practical alternative to heat pump
water heaters.
) The concept of drain water
heat recovery is far from new. At least two other devices - the Earthstar
Graywater Heat Reclaimer and the Drain Gain - have been on the market for
several years. And the energy-saving potential has been well-documented.
) Proskiw Engineering Ltd.
performed an extensive analysis of one prototype system that has been operating
in the Manitoba Advanced House, part of the Canadian Advanced Houses program.
) Proskiw concluded that a
well-designed graywater heat recovery system can, in practice, save 42% of
total water heating energy and theoretically as much as 50%.
) All those other systems,
however, include water storage tanks which, while increasing overall
performance, also increase size and cost considerably.
) The GFX uses a simpler and
less-expensive approach.
) For anyone wondering how
recovering heat from lukewarm drain water in a shower can triple the capacity
of an electric water heater, the answer is quite simple, though not intuitive.
) The GFX is now being
demonstrated in several projects, including the National Association of
Home-builders Research Center Twenty-First Century Townhouse project and the
Toronto Healthy House.
) This simple but
innovative product is a no-brainer for homes with electric water heaters and a
cost-effective energy saver for homes with gas heaters. (Excerpts from “Extraordinary
Water Heat Recovery Device”, Energy Design Update (EDU),
December 1996)
