Ask Caleffi

Straight from the Ask Caleffi Podcast studio, Greg and Dan dive into boiler protection.  Let's face it when high-temperature, mid-efficient boilers condense... it's a mess!  How can that be prevented?  Greg and Dan talk about solutions, including a "Swiss Army Knife" approach.  They discuss how the ThermoProtec thermostatic mixing valves work and where they should be piped with steel, cast iron, and copper tube style boilers to ensure that they automatically control the return water temperature, preventing condensation of water vapor contained in the flue gas.  Familiar with a soot vac?  Don't forget maintenance!

Greg and Dan invite "the dynamo of donut testing" to the series, the one and only Cody Mack.  Recirc creep is something that plumbers no doubt experience.  But, what is recirculation creep, when does it occur, what are the symptoms and - most importantly - what is the solution for your domestic hot water system?   They'll discuss ASSE 1017 and thermostatic mixing valves.  Can an aquastat be installed to fix the problem?  Are certain facilities more at risk?  What is the impact of piping practices?  Can I dig deeper (show me the resources!).  

Don't know Cody?  He serves as an education and training manager in North America for Caleffi.  Cody also is behind-the-camera in the popular series "5 Things You Need to Know" video series.  Feel free to watch.

Greg and Dan welcome Kevin Freidt, Caleffi Director Product Management & Technical Support (a..k.a. The Dr. of Disinfection) to the microphone.  They explore the fascinating topic of Legionella bacteria and its impact in domestic hot water systems.  Kevin starts with "bug basics":  where does the bacteria originate, when is it dangerous, what causes it to proliferate and how is it contained?  He discusses dead legs in potable water piping systems and explains how water becomes "old."  Not familiar with the ASHRAE 188 Standard?  Take note!  It's an important reference guide.  The Ask Caleffi Team completes this podcast with an interesting discussion on how we can ensure safety in our water systems.

Greg and Dan are behind-the-mic to discuss why you may want to select an electronic mixing valve for your next application.  They discuss how this digital valve is different from a thermostatic valve.  Why would you install a valve like this?  How about trouble-shooting... will a digital valve make a difference in problem resolution?  "This valve is electronic... wires are involved for installation.  I'm a plumber.  Helpl!"  Our Ask Caleffi team offers plumber-friendly installation tips!  Thermal disinfection?  Anti-scald?  Now you're talking!  Thanks for tuning in.

Thermal balancing in Domestic Hot Water systems.  Why is it necessary?  (hint:  water moves into the path of least resistance)  What's the difference between manual and automatic balancing valves?  Where are the valves installed?  How are these special valves maintained?  (ahem.... water quality is key!) 

Greg and Dan are back to answer these questions and discuss a real-time problem solver in this Episode of the Ask Caleffi podcast series.
