anyone has used the GFX heat exchangers, have they experienced additional
clogs in the drain? </FONT></SPAN></DIV>

<DIV><SPAN class=203041313-08122005><FONT face=Arial color=#0000ff size=2>My
concern would be is that if you remove too much heat from the draining
material, the grease component would tend to solidify and over time could end
up clogging the drain after where the heat exchanger device is
installed. One of the benefits of draining hot water is that it keeps
the grease in a fluid state.</FONT></SPAN></DIV>

could be an over reaction, but has made me reluctant to offer this as an
efficiency option in restaurants.</FONT></SPAN></DIV>
