In Episode 12, so I'm supposed to select a thermostatic mixing valve for a tank-type water heater; how do I figure out what to provide, where do I start? Greg and Dan will give you the straight scoop to help make your decision easy and make you look good in your customer's eyes. Your customer's domestic water system is not delivering heat correctly.  What do you do?  You listen in to this episode of the Ask Caleffi podcast where Greg and Dan discuss ASSE 1017 (not to be confused with ASSE1070!), Point-of-Distribution valves, and how to size.  They stress the importance of understanding a thermostatic mixing valve's minimum and maximum flow rate thresholds when combined with pressure drop.  Greg and Dan discuss what types of products will complement existing systems that do not have recirculation loops such as a "high/low" valve assembly or an electronic mixing valve.  Their goal is to help you determine how to apply the proper valve for the circumstance at hand.
