Bell & Gossett’s Little Red School

House Visits New York & New Jersey

-

ALL DAY IN-PERON SEMINARS ON HYDRONIC AND

STEAM HVAC SYSTEMS, AND PLUMBING SYSTEM DESIGN

Welcome to the 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.

All Day In-Person Class Sessions

Steam Fundamentals

(Steam Basics and Optimization)

This presentation discusses the basics of steam

systems – reviewing steam tables, latent heat,

pressure and temperature relationships, etc. Onepipe

and two pipe systems are reviewed, along

with different return systems. Steam trap types

are reviewed in detail. Vacuum condensate return

systems are reviewed, along with TRV devices.

1.0-CEU

Time: 1-hour

Hydronic System Pressurization and Air Control (Air Management in Hydronic Systems) 

This presentation differentiates between “air control” and “air elimination” systems, providing information on components required to make a closed system work properly; with a large focus on expansion tank selection and the role an expansion tank plays in proper hydronic water pressure control. Some B&G products are discussed.

1.0-CEU

Time: 1-hour

Centrifugal Pump Fundamentals 

This presentation discusses centrifugal pump fundamentals, from developing the pump curve, to pump components, parallel & series applications, NPSH considerations, open & closed system head, the development of the system curve and the presentation discusses VFD operation, minimum control head requirements, PLEV – part load efficiency ratings and more. Some B&G products are discussed. 

1.0-CEU

Time: 1-hour

Pumping Strategies 

This presentation will compare primary/secondary piping to variable-primary pumping, zone pumps to control valves, mixing and pumping for low temp operation tied into higher temp loops, etc. 

1.0-CEU

Time: 1-hour

Balancing Fundamentals 

This presentation provides a history of balancing, discussing fundamentals such as Cv value, what it is and why it is important. Examples of unbalanced circuits and resulting overflows are demonstrated. Pressure independent balancing is explained and the latest PICV technology; reviewing the many benefits offered by these improved devices. Traditional VFD operation is explained and the newer “sensorless” VFD technology is discussed and demystified. 

1.0-CEU

Time: 1.0-hour  

Electrification Made Practical 

This presentation looks at how power is produced at the plant level, the mix of fossil fuel and non-fossil fuel-based energy within our energy grid. “Point-of-Use” efficiency of electric appliances. The COP requirements of heat pumps required to be at parity with condensing gas fired units. Why “electrification” is a “green” technology, even with the current fossil fuel mix, the costs for fully electric systems verse conventional systems, and why hybrid systems make sense ecologically and financially.

Webinar "Master Class Sessions"

Steam Piping Design 

This presentation provides a “how-to” instruction on sizing steam piping and, best practices for piping layout, etc. 

1.0-CEU

Time: 1.0-hour

Controlling Condensing Boilers & Water Heaters 

This presentation looks at the efficiency curves of condensing boilers and compares these curves to NYC weather bin data to determine the efficiency of a condensing boiler over a heating season when it is designed for non-condensing design temperatures of 180F-160F. Boiler outside air reset control savings are compared to pump VFD savings; control options are discussed. Domestic hot water heater piping design is demonstrated to have a impact on domestic hot water heater efficiency. Some Lochinvar products are discussed along the way. 

1.0-PDH

Time: 1-hour

Hydronic Equipment Selection

(Systemwise Demo) 

Learn how to properly select equipment and design hydronic systems while learning to use B&G’s online selection tool “Systemwise.” Systemwise provides one location to select pumps, suction diffusers, triple duty valves, air separators, expansion tanks, and PICV’s. The software generates schedules in Excel, provides 2D CAD files and REVIT files, CSI-format specifications, submittal sheets and more. This presentation provides a demo of the system along with application knowledge every design engineer should know. 

PDH-N/A

Time: 1-hour

The Art and Science of Domestic Hot Water Design 

This presentation covers the fundamentals of heat transfer; dissecting each variable. It covers fixture accounting, occupancy assumptions, fixture schedules, DHW percentages, cold-water requirements, fixture units, diversity factors, and high level assumptions. 

1.0-PDH

Time: 1.0 hour

High-rise Building Plumbing Design 

This presentation provides guidance on booster pump sizing, ways to address plumbing layouts in buildings with multiple pressure zones, how to best address DHW building recirculation requirements, issues with piping distribution, and air entrapment.

1.0-PDH

Time: 1-hour

Wallace Eannace

Engineer “SNAP” Schedule 

This presentation provides an overview of the WEA Schedule Template. This tool is a useful tool for specifying engineers. It provides preconfigured equipment schedules and standard notes for a plethora of HVAC and plumbing equipment. In addition, it provided pre-filled information for many products, hyperlinks to manufacturers websites, so users can quickly find and download product data. There are also links to equipment selection tools, CAD libraries, etc.
