Understanding Primary Secondary Pumping Part 4: “What happens when...?”

/

By Chris Edmondson

Now that we know what happens when we vary flows and mix temperatures in a primary secondary pumping system, let’s explore these theories in some more realistic scenarios. 

As discussed in a previous blogs, when it comes to primary secondary systems, one of three flow patterns is always in occurrence:

What happens in a pipe when water of two different temperatures (and perhaps different flow rates) merge? 

There’s a pretty straightforward formula that tells you exactly what the resultant water temperature will be. In this blog, we’ll go over that calculation, as well as take a closer look at how blended temperatures

Are you involved in the design or installation of hydronic systems?  Do you anticipate becoming involved?

 If you answered yes to either of these questions, this blog series on primary/secondary pumping will interest you.  If you are a hydronic’s veteran, feel free to skip the first few blogs in the series – they may be too much of a review.  Better yet, pass them onto a junior associate and
