Why use heat transfer plates?

Let’s take the increased profit potential, longer heat transfer plate installation time, off the table.

I see you can lower the water temperature. Due to the improved heat transfer efficiency, it can be reduced by a factor of 40-50.

But wouldn’t it be possible to get the same result by installing 2 to 3 times as much PEX per square foot? at a lower cost?


Let’s say a 5X heat transfer plate costs the equivalent of 1 foot of PEX per square foot. I can’t see the cost/benefit in favor of the heat transfer plate!

I realize more PEX = more cassava and higher head pump.
