Here is the new video on how to make a hybrid heat exchanger using copper and plastic. The heat exchanger similar in design to the first heat exchanger. The difference being that I used copper fittings and pipe to make the outer chamber in the first build.
By using PVC fittings and pipe in the new heat exchanger build I was able to reduce the cost of building by 85%.You still need to use copper as the material for the heat transfer material. Plastic is a great insulator but is a horrible heat conductor.
If you plan on having fluids run through the exchanger that are above 160°F, do not bother using plastic. At this point you need to do an ALL copper build.
Materials used for this build
2- 2″PVC Tee
2- 2″Plastic/cast x 1-1/2″ copper MJ coupling
2 feet 2″ PVC pipe
2.5 feet 1-1/2″ type L copper (blue writing)
You will need to purchase PVC purple primer and schedule 40 glue. BOTH are needed to properly glue PVC fittings and pipe.
