Maybe bypass line another expense we would not do, no real reason unless coil in economiser springs a leak (which does happen occasionally, once every 20 years, which our 20 years was up this year).
I agree Ranger1! leak in the eco coil happens once every 20-200 years max. but what I have experienced is that instead of using a float valve, a danfoss level indicator is used instead, and they tend to fail and flood the economizer because they can't keep up with the boiling of the liquid, or the electronics fail...

Seriously, what if wrong with using a good old fashion float valve?


I was just wondering if flow-flow or counter flow would make any difference
