Hydronic Systems Design Manual

This manual was designed for use with TECA's Quality First™ Hydronic Systems Design course.

9th Edition, September 2024

230 pages, coil-bound book

The Hydronic System Design course provides the guidance supporting the certification of  technicians work with Hydronic Heating and Domestic Hot Water (DHW) Systems, or who desire an understanding of the design considerations.

This manual supports the design and installation of Hydronic Heating & the ancillary components. Sizing methods, example drawings, de?nitions, and descriptions of essential features and functions of the equipment have been provided.

This manual and related certification cannot replace other trade certifications for plumbing, refrigeration, sheet metal, electrical, or gas fitting.

This manual contains the currently accepted building standards and practices of TECA industry members and associate members. The installer must be familiar with local building codes that impact the installation of HVAC systems. Building codes can vary from city to city, and there may be local variance from this manual content. TECA updates our training curriculums as much as possible to stay in step with evolving regulations.

The manual includes step-by-step heat loss, estimate, and design worksheets, examples of worksheet use, all necessary charts, tables and formulas in Imperial measurements, explanatory text, diagrams, pictures, and more.

The Hydronic Systems Design Manual covers the entire design process, including:

• Principals of energy transfer, heat loss, & properties of fluids
• Pipe sizing & determining equivalent lengths
• Calculating system loads
• Calculating domestic hot water loads, & loads for custom plumbing fixtures
• Calculating & designing domestic hot water recirculation systems
• Analysis of different pump constructions, motor types, & circulation modes
• Expansion tank sizing & equipment selection
• Valve selection and comparison of a variety of valve designs
• Heat exchanger selection and design considerations
