Hindsight - From complex loops to clean headers: simplifying for reliability
The Glitch:
About 25 years ago, I began using a design technique that sends high temperature water to a remote manifold station serving low temperature floor heating circuits. Upon arrival at the manifold, that high temperature water gets mixed with water returning from the floor heating circuits to create a suitable supply water temperature for the embedded circuits. The rate of hot water flow to the manifold station was regulated by a variable speed “injection” pump. The concept is shown in figure 1.
Can you identify a problem with this approach or propose a better one?
