How??
  • Precise
  • BTU replacement
  • for BTU loss.

11
Energy act 2007
  • The law now provides that boiler manufacturers
    for residential hot water heating must provide a
    means for adjusting out put to actual heat load
    by 2012.
  • Exquisite Heat is the ideal solution.
  • We want you to try the product on your lab or
    sample home at your location.
  • Let us send you one to try.

12
Exquisite Heat
  • Adjusts heating/cooling supply temperature in
    response to Thermostat demand history.

13
Even BTU distribution
  • Lower heating plant (boiler/furnace)
    temperatures allow for more evenly delivered
    temperature to the space.

14
Temperature vs. Thermostat
  • The lower the medium temperature the longer it
    will take the thermostat to sense the change.

16
Simple Attachment
  • Two wire Thermostat parallel connection input.
  • Attach thermistor from supply output.
  • Connect low voltage control relay in series.
  • Attach 24 Vlt Power.
  • Program system variables.
  • Revisit until satisfied with installation
    settings.

What happened?
  • A changed philosophy of boiler control.
  • The new goal is to satisfy an Ideal Thermostat
    Demand ratio.
  • As Actual Thermostat Demand changes in relation
    to Ideal Thermostat Demand, the boiler output is
    adjusted every hour.

24
Efficiency
  • Reduced standby loss.
  • Increased heat exchange circulation
  • Better convection at baseboard and radiators.
  • Less back wall radiation loss.
  • Reduced piping radiation loss.
  • Less BTU generation to satisfy comfort needs.

25
Discussion of how it is done.
26
Assumption 1
  • Increased circulation delivers even comfort.

27
Assumption 2.
  • The closer the heating plant temperature is to
    the room temperature requirement, the more fuel
    efficient the system.

28
Thermostat
  • The thermostat takes all heat loss and heat gain
    into consideration.
  • The customer can adjust thermostat for personal
    comfort.
  • Thermostat activity can be used to adjust
    boiler, HVAC output to satisfy the space with
    ideal circulation.
  • The thermostat and energy source interact for
    comfort and efficiency.

  • For Exquisite Heat the constant is
  • IDEAL THERMOSTAT
  • DEMAND RATIO IDR

33
Ideal Demand Ratio
  • A preset thermostat On ratio 70
  • The circulation rate at which the heat source is
    providing the precise BTU supply for satisfaction
    and comfort distribution.
  • Thermostat On Circulation On

36
Constant
  • Ideal Thermostat Demand Ratio gives us a constant
    for comparison and adjustment.

37
Actual Thermostat Demand Ratio
  • The actual proportion of time a thermostat
    calls for comfortable heat in a given period of
    time. (60 minutes)
  • ADR

38
Actual Demand Ratio
  • Control takes thermostat on/off status reading
    every second.
  • 60 samples/minute x 60minutes
  • 3600 samples per hour.
  • If thermostat is on for 2520 times/3600 samples,
    the actual demand ratio
  • 2520/3600 .70 70

39
What information do we need?
  • Previous hour adjusted High Limit Temperature
    150 degrees F
  • Actual Demand Ratio
  • Ideal demand ratio (.70 )

40
Temperature change factor
  • Ideal demand ratio .70
  • Actual demand ratio .75
  • ((ADR-IDR) x10) TCF
  • ratio difference .75 - .70 .05
  • Temperature Change Factor .05 x 10 .5
  • Temperature change factor .5

41
Temperature Change Increment
  • Temp change increment is an arbitrary factor we
    use to determine the degree of response we want
    to make in the adjustment with the temperature
    change factor.
  • 1 F x .5 .5 F
  • 2 F x .5 1 F
  • 3 F x .5 1.5 F

42
New High Limit Temp calculation
  • Current High Temp Limit 150 F
  • ((.75 - .70) x 10) .5 x 3 F 1.5F
  • 150 deg F 1.5F 151.5 F
  • New High Temp Limit (Higher)

43
Limit Settings
  • 150 F 1.5F New High Temp Limit (Higher)
    151.5 F
  • Differential of 10 F
  • High Limit 151.5F
  • Low limit of 141.5 F

44
Temperature change factor -
Ideal demand ratio .70 Actual Demand ratio .55
  • Temp. Change factor ((.55 - .70) x10) -1.5
  • Temp Change increment 3 degrees F
  • Current High Temp Limit HT 150 degrees F
  • ((.55 - .70) x 10)) -1.5 x 3 degrees F -4.5F
  • 150F 4.5F New High Temp Limit
  • (Lower)145.5 degrees F

45
Factory Settings
  • Each control comes from the factory set up to
    attach and run.
  • No computer knowledge necessary is needed to
    install Exquisite Heat control.
  • Advanced laptop programming is available.
  • A programming sheet is available to have the
    factory set up needed settings.

46
All Variables are changeable
  • Ideal ratio .5-.8
  • Incremental temp change values (1-5F)
  • Sample and cycle times 5-120 min
  • High and Low safety limits for alarms and reset
    100, 120, 130 160, 190, 200
  • Initial start up High Temp set 140 F-190F
  • Temperature Differential 1-20 degrees
  • Low limit High Temp limit Temp. Differential

48
Minute to Minute Comfort
  • Between analysis within the hour, the thermostat
    can increase the call for heat/cool, by running
    more or less than the Ideal Demand ratio of 70
  • If chillier, the thermostat can run up to 100.
  • If warmer, the thermostat runs less than 70.
  • The thermostat always responds to the call.
  • We use TT information for analysis.

50
What has been done
  • Changed the philosophy of boiler control.
  • The new goal is to give heat to satisfy a fixed
    Ideal Thermostat Demand ratio.
  • We adjust the boiler output to meet that Ideal
    demand at the thermostat.
  • We provide a more comfortable and more efficient
    method of heating interior space.

51
A word about savings.
  • Every building has a different relationship with
    its heating plant.
  • Some waste a lot. Most waste a lot.
  • Most have comfort problems.
  • Savings on fuels can range from 5-30
  • Exquisite Heat will run it more comfortably and
    efficiently for sure.

52
Reduction of chimney waste
  • Air Pollutants CO2, NO, etc.
  • Particulates heat

53
Domestic Hot Water
  • A Second thermistor is provided to monitor
    Domestic Hot Water. If the Thermostat does not
    call for heat for one hour the second thermistor
    is used to satisfy domestic hot water limit
    temperatures. ( 120F-150F)

54
Multi Zone Satisfaction
  • Most cases are satisfied by attaching analysis
    zone to average zone in system. The rest of the
    zones will float with Thermostat call activity.

Shut Down
  • In the event of a control shut down
  • Power failure
  • Computer switches disconnect control relay off
    and returns HVAC to in series factory low voltage
    control.

61
Alarms
  • Normally open or closed alarm relay is activated
    upon shut down, or safety settings.
  • Trigger local alarm, communicator, or security
    system.
  • Alarm central or direct dialer to owner and/or
    contractor.
  • Additional flood, heat, smoke detection.
