HYDRONIC, STEAM, HVAC & PLUMBING SYSTEM DESIGN

Welcome to the B&G Little Red Schoolhouse®

Since its inception in 1954, Bell & Gossett’s Little Red Schoolhouse has offered training for hydronic and steam HVAC, and plumbing systems application, design and maintenance. Known as the industry’s educator, the Schoolhouse sets itself apart by emphasizing a systems-based concept of teaching, rather than focusing on product features and benefits.

Our training curriculum is created using the core hydronic and steam engineering principles established by Gil Carlson and his Bell & Gossett engineering team back in the 1950s. Training modules are frequently updated to support advancements in equipment design and operation, along with the evolving focus on sustainability, decarbonization, and electrification of hydronic systems.

CLASS SESSIONS

Hydronic Fundamentals

Join Xylem’s Bell & Gossett for a brief discussion on the basics of heat transfer in hydronic applications.

In this session, the Xylem team will summarize the following for attendees:

• Explain the concept of Zone Pumping

• Review flow and pressure drop relationship in pipe

• Summarize the System and Pump Curve interaction for pump flow determination

• Outline Distributed Pumping piping configuration options

• Discuss suggested pump control strategy for each layout



• Apply a design scenario to compare a pump versus control valve for coil flow control



0.1 CEU

Time: 1 hour

Flow Balancing

Attendees of this seminar will learn about system efficiency and the importance of system balancing. Xylem will discuss why balance is important to a well-designed and commissioned HVAC system.

In this session, the Xylem team will summarize the following for attendees:

• Discuss where balance and flow measurement is needed in closed and open hydronic systems

• Review the negative impacts of an unbalanced system

• Explore self-balancing techniques that can be utilized via system design

• Compare and contrast different balance valve technologies and the pros & cons associated with each



0.1 CEU

Time: 1 hour

Variable Speed Pumping Fundamentals

In this session, the Xylem team will summarize the following for attendees:



• Address the fundamental issue solved by applying variable speed operation to pumps.

• Define variable and constant head loss and how these parameters physically correlate to a closed loop hydronic system

• Introduce and demonstrate the different control strategies available when controlling variable speed pumps.

0.1 CEU

Time: 1 hour

Air Management Basics

In this session, the Xylem team will summarize the following for attendees:

• Highlight the strategies used to control air and use it for the stability of any closed loop system.

• Describe a systems pressure band and required components

• Identify the difference between air control and air elimination

• Illustrate how to determine the systems initial cold fill pressure

• Calculate the required precharge pressure for a diaphragm or bladder tank



• Analyze the systems required tank size and discuss pump and tank location best practices

0.1 CEU

Time: 1 hour

Basics of Primary Secondary Pumping System Design

Primary-Secondary Pumping

• Definitions

• “Common” Pipe Design

• Cross-Over Bridges

• The Law of the Tee



• Conservation of Energy

0.1 CEU

Time: 1 hour

Steam System Design Fundamentals - Low Pressure Steam Heating

Attendees of this class will gain a thorough understanding of steam properties and how they are used in heating applications and pipe sizing. An example of how to size steam pipe utilizing ASHRAE’s sizing charts will be provided.

During this seminar, Xylem will:

• Explain why steam is used in heating applications

• Define one pipe and two pipe heating systems

• Analyze the thermodynamic properties of steam

• Describe sensible and latent heat

• Identify the effects of pressure on steam

• Examine the systems required steam flow rate

• Determine maximum pressure drop and velocity limits

• Illustrate how to size steam pipe using ASHRAE’s sizing charts

• Outline condensate return piping configurations



• Explain the purpose, sizing, and operation of Condensate Pumping System, Boiler feed Pumping System, Vacuum Producing System
