This course will introduce you to systems, equipment and design guidelines for high temperature water (HTW) heating plants. HTW systems are used for heating multi-building facilities such as campuses and industrial and commercial activities. The advantage HTW systems have over steam heating systems is that the pressurized water in HTW systems has a much greater thermal storage capacity, resulting in smaller pipe and pump sizes. In this course you will learn about the different types of HTW systems, distribution schematics, hot water generators, pressurization methods, expansion vessels, pumps and controls. Course Outline 1. General Requirements 2. Definitions 3. Types of Systems 4. System Water Velocities 5. Types of Distribution Circuits 6. Hot Water Generators 7. Pressurization 8. Expansion Vessels 9. Pumps 10. Controls
