I know that you aren't supposed to use copper or alluminum with WVO, but what about bio-d? Are the restrictions that same? What are some of the other guys using? is it all mild steel piping? If so, what size/gauge and how are you setting up your coils in your tanks? I have a slip tank for this set up and want to get it firgured out before I start buying, cutting or welding.
Thanks

 

Anything but copper is ok. If you blend to B-80 in winter you do not have to heat the tanks at all.

What temps are you referring to fabmandelux? Also, please check your private messages fabmandelux.

 

So far I have had no problems with B-80 down to 12 deg F. In the last 2 years that is the lowest temps we've had. B-50 should be good to 0 deg according to the cold tests i've done.

The answer to your PM is yes.
