When it comes time to think about boiler replacement, part of the discussion, particularly with oil heat, is the consideration of swapping like for like OR migrating to a condensing boiler replacement. In this webinar, Jody Samuell, Manager of Engineer Education, walks us through the decision making process and will discuss the project execution. You'll learn: 

- How much savings can I realize with the conversion? 
- Establishing a baseline with heat loss calcs 
- A hidden cost: venting options (including make-up air) with oil as compared to a condensing gas boiler 
- Piping options: What stays? What goes? 
- Adding in an indirect water heater: What do I need to consider? 
- Post installation: The savings don’t add up! How do I quantify the savings and what needs to be considered.

ARCHIVE - Utilizing Thermal Buffering In Hydronic Systems with Guest Speaker John Siegenthaler

Utilizing Thermal Buffering In Hydronic Systems
This webinar is now available in our online archive.

There are many types of hydronic systems where the rate of heat generation by the heat source is very different from the rate at which the building requires heat. When only one or two zones require heating, the output of the boiler far exceeds the rate of heat demand. This can lead to heat source short cycling, reduced efficiency and shorter equipment life.

One way to avert such conditions is to add thermal storage to the system.

Guest Speaker John Siegenthaler, P.E., will explore several ways to do this. He will discuss the hardware and sizing of thermal storage in a variety of systems, including those supplied by boilers, solar thermal collectors, heat pumps and biomass boilers. He will also describe unique control methods that maximize the performance of thermal storage.

- How do you know if thermal storage is necessary?
- What types of thermal storage tanks are available?
- What are the pros and cons of pressurized vs unpressurized thermal storage?
- How do you size a thermal storage tank for different apps?
- How do you integrate a thermal storage tank with multiple heat sources?
- What is a thermocline, and how do you maintain it?
- When are ASME rated tanks necessary?
- What’s the best way to connect multiple thermal storage tanks?

John is a mechanical engineering graduate of Rensselaer Polytechnic Institute and a licensed professional engineer. He has over 30 years' experience in designing modern hydronic heating systems and is an industry leader and hydronic visionary. John is the author of Modern Hydronic Heating and numerous other publications dealing with hydronic heating including Plumbing and Mechanical, PM Engineer and Heating Plumbing Air Conditioning.

ARCHIVE - Water Quality in Hydronic Systems with Guest Speaker John Siegenthaler, P.E.

 

This webinar is now available in our online archive.

Take a look at webinar Q&A's.

Many installers simply fill their newly installed hydronic systems with water that’s available on site. Sometimes they’re “lucky” to have water with relatively low dissolved solids, stable pH and low turbidity. Other times they may not be so lucky. Although problems may not appear right away, the life of their new system could be significantly shortened by a combination of minerals in the water, solder flux residue, cutting oils in piping and glycol-based antifreeze solutions. 

John Siegenthaler, P.E., a seasoned hydronics leader and visionary, joins us at this month's webinar to provide an overview of the issues and will explain how to use demineralized water in combination with proper system commissioning to minimize water quality issues in hydronic systems.  You will learn:

- What are the consequences of poor water quality?
- What is demineralized water?
- Why demineralization is better than softening
- How to demineralize water - using Hydrofill
- Procedures for commissioning water in new systems

ARCHIVE - What is Flow Coefficient (Cv) and How to Apply?

Flow coefficient (Cv) is a relative measure of a device’s efficiency at allowing fluid to flow. How is Cv used in a hydronic or plumbing system?  Bob "Hot Rod" Rohr, Caleffi training and education manager, takes the mystery out!

This webinar is now available in our online archive.  Listen in - at your convenience - and learn about:

- How is pump sizing and component Cv related?
- What offers more  flow resistance: a 1” balancing valve with a Cv of 12, or a ¾” air separator with a Cv of 12?  
- My thermostatic mixing valve has a Cv rating of 3? Does that mean I can only run 3 gpm through it?
- Why do you say a fixed orifice type balancing valve has a constant Cv, and a variable orifice type valve has changing Cv?
- What does rated Cv mean?
- Why is zone valve Cv and close-off pressure rating inversely related?
- Caleffi radiant manifolds have a “combined supply & return” Cv of 1.23. Do I use this for pump sizing?
- What is the role of a fluid’s specific gravity on Cv?  How do I use this information?
- Are there products whose Cv value varies when operating conditions change? When do I need to be aware of this?

ARCHIVE - Zone Relay Controls for Hydronic Heating

Zone Relay Controls for Hydronic Heating
This webinar is now available in our online archive.

Take a look at webinar Q&A's.

A hydronic heating system can be a relatively straight forward single-zoned system or a more complex multi-zoned system with a montage of pumps and valves working in concert with the boiler and thermostats. Mike Schreiner, Director of Operations at Caleffi with 29.41 years' of engineering experience, will explain the command center of these heating systems - the zone relay control.  He’ll discuss the design of the controls and how to apply them for reliable system operation. You'll learn:

- How can I prevent zone pumps from running when a boiler is in warm weather shutdown?
- What is the best way to control variable speed pumps?
- Why have a valve control and pump control communicate with each other? How is that set up?
- How can I control multiple secondary pumps and zone valves?
- How many controls can communicate together?         

Mike is a mechanical engineering technology graduate from the Milwaukee School of Engineering.  He invested 16 years’ of his career as a product design engineer at two valve manufacturers.  Mike’s passion as a product designer and inventor has resulted in four U.S. and international patents for control valves.  He has been with Caleffi for 14 years as a product designer and serves as the Engineering and Operations Director.
