Guys-
We're getting a little topic drift
I was looking for someone with installation or specification experience w/ GFX product.
I'm not looking for theoretical discussion, I want some real world experience.
What model did you buy, how did you size it / choose it, how did you install it, how has it worked out?

Having struggle through the info on GFX website, it looks like fouling (at least from what they say) is not a problem due to the very high flow velocity.
As opposed to a "flooded" heat exchanger where flow velocity is much lower
cheers Bob
I concur, with a heat exchanger that never floods, the water velocity down the walls is VERY VERY rapid. Solids will tend to bump the sides infrequently as they fall thru the 3 to 6 foot length. GFX has documented installations that include blackwater processing that have been in continuous service for 5-9 years with NO clogging, no cleaning needed. Since the installation method uses clamps, it would then be easy to open one up after a few years to see what gunk is caked to the inside walls.
But with the water velocity quoted, even a small about of residue that sticks when a solid bumps the wall will be quickly washed away by the rapidly flowing water
And the efficiency is fairly low, especially with a bathtub.

And your heat exchanger does nothing to correct that either as BOTH require flowing warm waste water to do their work
Wrong.

Ask at the Wall.
