Unit 8 Overview

Whenever connecting a collector to a tank or heat exchanger the piping must be metal. In order to achieve a lasting and durable connection the most popular way to connect is sweat soldering. There are many ways to do sweat soldering. The videos demonstrate ways to sweat solder.

The most common connection is copper piping. Copper pipes are called "sticks." I finally can get away from calling them pipes! A stick of copper comes generally in 10’ lengths. There are three thicknesses:

- M is a red stripe
- L is a blue stripe
- K is a green stripe

K is the thicker and M is the smaller.
