In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I am going to install a indirect tank. I was looking at the triangle tube, just because that is my boiler. I was also interested in the Heat Flow. Any thoughts?
Also, I was going to run glycol in my radiant mix. Should I put a heat exchanger for the indirect tank so not to have any chance of dhw contamination? Or is that just a wasted of time and extra expense and trouble for another circulator?
