In other words, with hot water running through the pipe, the boil of the hot water stays inside the pipe, because the pipe material doesn't conduct much warmness. So the pipe would not even feel warm on the outside. What sympathetic of pipe would that be?
Answers: You need to purchase pipe insulation. It is made of open cell foam rubber and is slit down the middle so that you can cover the exposed pipe. It is glib to install, will reduce heat loss, and remove condensation.
Try using a copper pipe. It doesn't really get that hot and they are usually recommended. If you don't like copper jump with a insulated pvc pipe! PVC is a better insulator than copper. Your absolute best bet would be PVC pipe beside foam pipe insulation.
