7 Competition We cant afford to fight.
8 Integrated Systems Hydro-Air Systems Air/Water Heat Exchangers Water/Air Heat Exchangers
9 Common Processes Load calculations Distribution planning Zoning Others?
10 Introduction to the radiant side. 10 Objective 2
11 Hydronics Hydronics is a term that was introduced in the 1940s to refer to a system of heating or cooling of an internal area using fluids in either vapor or water form.
12 Hydronics These fluids are then circulated throughout a series of pipes or tubes to produce a desired room temperature.
13 Hydronics Although this official term was established in the 1940s, the process of using hydronics or "wet" materials to first heat, then later to cool, a home has been in existence for many years, beginning with the invention of cast iron boilers.
14 Old School Non-condensing boiler Single speed pumps Single zone Baseboard
15 Principal Components Heat Source Distribution System Radiator/Heat Exchanger
16 Heat Source Fuels Boilers Solar Geothermal
17 The system doesnt care where the BTUs come from.
18 Distribution Systems Piping PEX
19 Distribution Strategies Home run Ladder Injection Others?
22 Advantages Efficiency of heat transfer Size of distribution systems Cost of operation Durability of system Comfort
23 Disadvantages More expensive - first cost Designer skills Installer skills Service skills
24 Provide the resources to include radiant technologies in classrooms. Objective 3
25 Sources of Training Radiant Panel Association The ESCO Group Manufacturers* Others? * - Caution: Boiler, pump, control, component and PEX manufacturers know and tend to focus on their products way of performing.
26 Your training program must teach the building is a SYSTEM not a collection of unrelated components.
