Garn Install 15 mos. and winding down!

I made an error in my last drawing. This is how the flow works on the HX. The work cutting up the old system took all day yesterday, but my barn cat learned a few new cuss words and so it was well worth it. :bug:

Dave, Kabbot... Good catch. Since the Garn is a heat supply, the colors on that side are backwards, as your input side will be the hottest water. As drawn in # 71, the Garn side is getting heat from the HX instead of supplying heat to it.

Counter-flow is sort of counter intuitive, but the rule in any heat exchanger is that your best results will come when the flows run OPPOSITE each other... The flow arrows are right, and the house side is drawn correctly, but the Garn side colors are definitely backwards.

Yes, that corrected drawing does look better... And don't start worrying until the cat starts using it's new vocabulary on you! :lol:
