Sidearm Heat Exchangers

These copper sidearms are 1.5" dia. with (7) 3/8 tubes inside, 3/4" end ports and 1" side ports. Length of shell is 26". These are true tube and shell as opposed to 1 tube within another.

The stainless models have a single fin enhanced tube that increases the heat transfer 5-8 times better than a smooth pipe.

From the outdoor boiler go to the top one inch port first to get best results.
