Last week, we created a chart showing the flow rates and temperatures in an example system so we could maximize the delta T at the boilers. Today we will show how this system example looks when laid out as a primary secondary tertiary system. Please note we are not showing the complete detail of the system trim which we will detail in a later article.

Here is our example:

Here is a P-S-T layout:

In the next two articles we will apply Laars and Aerco boilers to this system example.
