Program TitleSolar Water Heating Systems
Time, LocationOctober 3 (Wednesday, 9:00 am to 4:30 pm) San Francisco--PEC
Also OfferedOctober 03 (Wednesday, 9:00 am to 4:30 pm) Internet
DescriptionWe will provide an overview of the design, specification, and installation aspects of Solar Water Heating systems for both commercial and residential applications. We will present a wide range of systems from simple residential water heating to combined systems that serve multiple heating loads at commercial facilities. We will cover different system types (open-loop, closed-loop, and drainback), focusing on each system's particular advantages and disadvantages. In addition to an overview of system theory and operation, we will discuss component selection and sizing. The course is intended to provide contractors, architects, and designers with the information necessary to estimate system costs and savings, design and specify systems, and review installation issues that will guarantee proper operation of the system.

We will discuss the following system types and applications:
Residential Domestic Water Heating
Residential Combi-Systems (combined water and space heating)
Nonresidential Water Heating (e.g,. multifamily dwellings, hospitals, laundries)
Nonresidential Combi-Systems (e.g,. fitness facilities with showers, pools, and spas)
Audience LevelBasic level and/or refresher for seasoned professionals in related fields; however, it is highly recommended that participants have a basic understanding of plumbing components and terminology.
