Radiant 101 Low Temp Distribution for High
Efficiency Applications
  • Tom Meyer
  • CSME, GGP, CBCP, QCxP, EBCP
  • Director, Government and Professional Development

2
Objectives
  1. Learn to integrate radiant-low temperature
    distribution high efficiency applications into
    training.
  2. Introduction to the radiant side.
  3. Provide the resources to include radiant
    technologies in classrooms.

Learn to integrate radiant-low temperature
distribution high efficiency applications into
training.
Objective 1
4
Competition
  • Wet head

5
Competition
  • Air head

6
Competition
  • Scorched Air

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.
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?

20
RadiatorHeat Exchanger
  • Radiators
  • Baseboard
  • Floors
  • Walls
  • Ceilings
  • Artwork?

21
Unique Applications
  • Snow/Ice Melt
  • Indirect Potable Water Heating
  • 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.
