This is a 48" tube-in-tube side-arm heat exchanger with 3/4" hook up for the domestic water heater side, and 1" hook up for the wood stove/boiler side. This side-arm will work on any size hot water heater, though installation piping may vary depending on water heater dimensions. The inner copper tube is rifled in order to introduce turbulence within the heat exchanger which improves heat exchange performance. The side-arm comes dry-fit/unsoldered to more easily fit your exact installation.


  • Side arm heat exchangers are less prone to clogging than brazed plate heat exchangers
  • Fittings are dry fit (not sweated) to allow for easier installation in your specific application
  • Tubing can be easily cut down with standard pipe cutting tools
  • Fittings may be turned to desired degree off-center for easiest connection to your existing system!
