Plumbing & Mechanical will sponsor several special workshops by its columnists John Siegenthaler and Julius Ballanco, at NEX 2000 next month in Chicago.

Siegenthaler will present two workshops. The first will be "What's So Great About Hydronic Heating? 20 Things That Will Make You a Confident and Enthusiastic Promoter of Modern Hydronic Heating," on Oct. 6 from 1-3 p.m. This brand-new program will detail 20 specific benefits of hydronic heating that builders, architects and engineers should know.

On Oct. 7, Siegenthaler presents "Modern Piping Methods for Multi-Load Hydronic Systems," a two-hour session beginning at 8:30 a.m. This is a technical session for contractors, wholesalers and engineers with some hydronics experience. Siegenthaler will review how to make the transition from a simple hydronic system to the more advanced and extensive systems so often used in new custom housing.

A detailed workbook, available only at NEX, will be provided to attendees of either Siegenthaler workshop.

Ballanco's two-hour session, "New Technology to Increase Profits, " Oct. 7 at 1 p.m., will focus on profit-making advances in plumbing products. Ballanco will review the new technologies and how they can be integrated into a contracting business. Labor savings and bidding processes with each also will be explored.

Admission to these seminars is free to all NEX 2000 visitors. For more information and free advance registration, visit the NEX Web site: or contact the show office by phone: 312/464-0090 or fax: 312/464-0091.
