What Do You Tell Members About Electric
Heaters?Research and Recommendations
CRN End Use Solutions Member Advisory
Committee December 11, 2006 Ed Thomas, Market

Topics Ill Cover Today
  • Member Questions and Co-op Answers
  • What I Learned in France
  • Performance Standards
  • Research Findings
  • Efficient Design and Load Control
  • Proposed CRN Action Steps
  • Technical Surveillance Report
  • Guest Speakers
  • Hardware Tests

3
Co-op Threat
  • 50 savings claims of Paul Harvey and Sun
    Heaters
  • Turn down your thermostat and carry heater
    room-to-room
  • Ignores importance of home sealing and insulation
  • Preying on Seniors and Young Families

4
Member Questions
  • Whats the most affordable way to heat my home
    with electricity?
  • I just bought one of those electric heaters
    advertised in the paper and on Paul Harvey. They
    say I will save 50 on my energy bill. Isnt
    that great?

5
Co-op Answers
  • Electric Heat is 100 Efficient
  • Electric Heat is Too Expensive
  • Electric Heat is Bad for the Co-ops Peak Demand
  • Burn Wood and Buy More Blankets (but not electric
    ones)

6
In the Real World....
  • Members Want Affordable Comfort
  • Co-ops Want to Clip Peaks and Fill Valleys
  • Members Buy Heaters at WalMart, Home Depot and
    now.. from Paul Harvey
  • Members Decide How to Heat Their Homes, Not
    Co-ops
  • Homes Dont Pay Demand Charges... Yet... So.....
  • Electric Heat is Cheaper Than Propane
  • For Rural Homeowners

7
CRN Should Help Co-opsAnswer These Questions
  • What should co-ops be telling members about
    electric heat?
  • What are co-op economics vs. member economics?
  • When is electricity the right choice for
    affordable comfort? And in those cases, how can
    electricity best provide affordable comfort?
  • Whats better whole house or room-to-room
    heaters?
  • When appropriate, what should I look for when
    selecting a portable heater?
  • How can members make their homes more comfortable
    and reduce their overall heating needs? (hint
    sealing and insulation)

8
What I learned in France
  • International standards for heater performance
  • Key Factors in Design and Manufacturing
  • Utility-driven research and development projects

9
European Standards
  • International Electrotechnical Commission
    (www.ice.ch) sets performance measurement
    standards
  • In France, electric heater thermostats must have
  • maximum 0.9 degree F temperature swing
  • maximum 2.7 degree F droop
  • 30 years ago, France banned all electric heaters
    that allow warm air to creep along outside walls
    such as vertical outlet heaters or baseboards

10
Designed to Heat a Room
11
Designed to Heat a Wall
12
Canadian Standards
  • Similar thermostat performance standard
  • Also sets thermostat precision
  • when thermostat is at 68 degrees F, the
    temperature measured in center of room shall not
    deviate by more than 0.5 degree C.
  • Standard was updated in 2006
  • Expected to become code requirement in 2007 or
    2008 in Quebec, Ontario and British Columbia

13
Hydro-Quebec
  • Extensive testing of electric heaters and
    thermostat since the early 90's at Laboratory for
    Electrical Technologies
  • Concluded electronic thermostat reduces energy
    consumption by about 10
  • Subsidizes installation of electronic thermostats
    meeting CSA performance standard

14
ConvectAir Labs
  • 4 Electric heating factories have own lab
  • 6 Dual-climate testing rooms total
  • 2 Recognized by French Central Laboratory for
    Electrical Industries for standards approval

15
ConvectAir Labs conduct
  • Quality control for equipment and all measuring
    instruments used in the testing and production
    processes
  • Safety tests (thermal, electric, wet environment)
  • Performance tests (impact on room temperature
    under different weather conditions
  • Comfort tests (temperature distribution, radiant
    vs. air temperatures, impact of air changes, air
    movement), electrical consumption tests and
    standby heat loss measurements
  • Provide visualization tools (surface temperatures
    of room surfaces, temperature of heater surfaces
    and components, convective air movements in a
    room, impact of a radiant heat source)

16
Utility-DrivenResearch and Development
  • Efficiency Research Findings
  • Key Factors in Design and Manufacturing
  • Sensory Marketing
  • Whole House Load Limiters

17
Efficiency Research Findings
  • Requires 20 more energy to maintain 68 deg F in
    a room using baseboards and mechanical
    thermostats than using natural convection heaters
    with electronic thermostats. 
  • Comfort was significantly improved using the
    convection heaters (more constant and more evenly
    distributed heat). 
  • Simulations using actual weather data for the
    Montreal area showed over 30 difference over
    entire heating season (with variations due to
    user behavior).
  • ConvectAir and HydroQuebec now conducting field
    comparisons in several apartment buildings

18
Key Factors in Design and Manufacturing
  • Electronic Thermostats with Setbacks and Zoning
  • Heating elements
  • Cabinets

19
Sensory Marketing
  • Électricité de France (EDF) created comfort and
    sensory evaluation" lab in 2003
  • Conducted multiple consumer tests in controlled
    environment to describe/quantify sensory
    perceptions
  • Using data to develop heating/cooling solutions
    create communication strategies based on sensory
    aspects of a product
  • Lead to development of new heater line in Europe,
    available in U.S. in 2008

20
Whole House Load Limiter
  • In France, residential electric meters limit
    power use in a home to a set Kw maximum.  If that
    maximum is exceeded, a breaker cuts the power. 
  • Load Controller applies variable load shedding
    cycle to
  • Room-by-room heaters or zones
  • ETS units (if any)
  • Water Heater
  • Central programmable thermostat provides
    automatic setback over two zones with instant
    cost and consumption data
  • Utility can adjust/impose limit on electric heat
    use during peak demand times
  • ConvectAir looking for utility demonstration
    sites in U.S.

21
Proposed CRN Action Steps
  • Technical Surveillance Report
  • HydroQuebec and EdF Speakers at CRN webcasts and
    conferences
  • Hardware Demonstrations for Energy Efficiency and
    Load Control
  • CRN Field Trip!!!

22
First Action Step
  • Draft and publish a Technical Surveillance Report
    on Portable Electric Heaters
  • Assist NRECA in producing Consumer Reports type
    templates for member newsletter articles and new
    releases
  • Guide co-ops to partner with reputable suppliers
    (and shun hucksters)
