Your customer's domestic water system is not delivering heat correctly.  What do you do?  You listen into this episode of the Ask Caleffi podcast!  Greg and Dan discuss ASSE 1017  Point-of-Distribution valves (not to be confused with ASSE1070!) and how to size them.  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.

It seems that hydronic zone valves have been around forever. They are pretty bulletproof!  But do you hear about end switches failing?  What's going on?  AND... what do I need to know before wiring a zone valve?

In this Episode, Greg and Dan discuss this common question from our Technical Support line:  what's wrong with my actuator?  Our Tech Support Gurus find that the culprit is typically a misapplication of the "end switch", a.k.a. the micro-switch.  They explain the role of an actuator that contains a micro-switch and what kind of inrush thresholds are required to operate them successfully.  They also talk about optimal installations including utilizing actuators with a ZVR relay control board that provides your customer with a top-notch product AND a top-notch warranty.

In this Episode Greg and Dan - our Ask Caleffi Podcast hosts - discuss what a scald-protection valve is and why they are SO important (protection protection protection!).  What temperature of water is safe?  Dangerous?  Who is most at risk?  Are there applicable industry guidelines (hint:  ASSE 1070)?

Learn about how they work, where they are used, and why they are so important in the industry.

It can be a time-consuming project to troubleshoot why a zone relay board doesn't "appear" to be working, especially when the heat is literally ON for the contractor, but OFF for their customer.  

Greg and Dan take our audience through a step-by-step process of isolating and solving the "no-heat" calls including how to locate the source of the power loss.  It's (another) don't-miss episode!

Why is my pressure reducing valve rattling, hammering.... screaming??

Greg and Dan take a new spin in this episode of the Ask Caleffi podcast series, inviting you into a "customer" technical support call in order to troubleshoot the problem.   They will discuss how a PRV should be sized (based on pipe size?).  Is there a more accurate methodology (hint: a design for flow rate!)?  What about install tips and maintenance?  (another hint:  debris is NOT a friend to PRVs).

The backflow preventer is a misunderstood piece of hardware in hydronic systems.  "My backflow preventer has failed.  It's dripping.  What should I do?"   It's easy to replace it.... but, has it really failed?

Likely the backflow preventer is doing it's job!  The culprit?  Debris stuck in the check valve.  Greg and Dan discuss how and why the backflow preventer can drip and what to do to eliminate the nuisance drip.

Need a video reference to see how this is accomplished?  Glad you asked!

Episode 4 focuses on the importance of having magnetic technology built into dirt separators. Highly efficient "dirt" removal, including both non-ferrous and ferrous (magnetic), is critical to protect today's high-efficiency heat exchangers and circulators. Caleffi is the North American market leader in magnetic dirt removal technology.
