    #1.6 Manual vs. Thermostatic: Which Balancing Strategy Is Right for Your Project?

    Ever stayed in a hotel where you have to turn the shower on, go grab breakfast, and come back just to find "warm" water? In this episode of Ask Caleffi, the team dives deep into the "why" and "how" of domestic hot water (DHW) balancing. Water is inherently lazy, it takes the path of least resistance. In a DHW system can mean that  the furthest risers in a building can be cold  while the closest ones hog all the heat. The crew breaks down the symptoms of an unbalanced system and compares the most popular solutions on the market today. From the old-school struggle of manual balancing valves to the modern efficiency of thermostatic balancing, we cover it all to help you save water, energy, and your sanity. In this episode, you’ll learn: The Ball Valve Myth: Why using a ball valve for balancing is a recipe for failure.Manual vs. Automatic: The pros and cons of fixed-flow cartridges versus the "hand grenade" (the 132 QuickSetter).Thermostatic Balancing: How to "zone" your DHW system by temperature rather than just flow.Legionella Management: A look at thermal disinfection and how to automate it using Building Automation Systems (BAS).Pump Protection: Why pairing balancing valves with ECM pumps in Delta P mode is critical to prevent pipe erosion.Don't forget to subscribe and leave a review wherever you listen.

    #42 Get In the Zone! (with Mike Schreiner)

    In this episode, Greg and Dan talk to "the man, the myth, the legend" of zone valves, Mike Schreiner, Caleffi CTO.   Mike has been working with zone valves for his entire career and is pleased to share his wealth of knowledge to help our Ask Caleffi audience learn: What's important when considering a zone valve?  How do you properly size?  What is the flow coefficient (a.k.a. Cv or differential pressure) and why is it important?  BTW:  there is a BIG difference between close-off pressure and system pressure!  Zone valves and actuators... say what?  In which application is a 2-way valve best used?  A 3-way?  How are end switches applied?  What's the difference between a micro-switch and a Reed switch?  Normally Opened.  Normally closed.  Why Z-one? (one valve for ALL!)  Valve versatility with union connections.  How about relay boards?  (you CAN'T wire a zone valve wrong with a relay board!) All this and MORE when you Get in the Zone with Mike!
