a NO. Heat transfer products (Munchkin) specifically says no...I am sure that no testing has been done with this in mind. Plus I am not sure what the reaction with the condensate would have with the copper...Good thought though. kpc

    Actually...

    I did this with the T50 Munchkin that is on loan from HTP. I did it without their authorization, and yes they are aware of it. I haven't pulled it apart yet to see what;s going on inside, but if its in good shape, I'm going to leave it.

    I set it up such that the condensate from teh waste ehat recovery unit will NOT roll back thorugh the appliances HXer. It rolls forward to a drip tee, then into my neutralizer/tree root killing machine. Didn't want to find out what happens to SS when copper is solution in a low pH fluid hits it...

    DO NOT TRY THIS AT HOME!!


    But, fear not. I have it from a VERY reliable source that a particular manufacturer will be coming out soon with a factory authorized add on waste heat recovery unit that will keep the thermal efficiency of these appliances above 94%, even with supply temps as high as 180 degrees F.!!

    Times, they are a changin', and if you're not keepin' up, you're fallin' behind. WAY behind, FAST.
