High boiler output is only required on a few
coldest days of the heating season.Most days
even comfort could be provided with reduced
energy expense.

Why are these high temps
  • The fellow who set the boiler at service time,
    did not want a low heat call on the coldest day
    of the year.
  • Folks did not have a way of regulating boiler
    temperatures.
  • Who cares what you spend, or how much you waste
    to the atmosphere????
  • Folks never complain if they are too warm.

8
Hey Folks
  • At Exquisite Heat we believe your heating system
    should be comfortable first.
  • We believe you deserve good comfort at least
    energy expense.

9
Hey Folks !!!!!
  • Can you see the problem here?
  • ANYONE ??
  • We are talking about 90 of buildings in the
    world.

Symptoms
  • Uneven comfort ( too warm-too cool)
  • Windows open - energy escape
  • Folks complain about comfort
  • Low humidity and dry skin
  • We raise the heat to warm cool spaces.
  • Excessive run times for boiler
  • Basement too hot- waste of energy
  • High Fuel bills
  • WHY?

For every 2 degrees we reduce boiler temperatures
1 savings on your gas or oil bill.
19
Desired Solutions
  • Even out the comfort in all rooms
  • Shut the windows in overheated rooms
  • Keep complaints down
  • Higher humidity levels, less dry skin
  • Set the Thermostat lower for all rooms
  • Reduced running of the boiler, saves fuel
  • Get the heat out of the basement, and into the
    rooms
  • Lets lower those fuel bills

20
WASTED
  • If your too hot or too cold, arent you wasting
    the
  • money you are already spending on Fuel for
    heating ?????

21
The Main Goal
  • Precise comfort replacement for
    building heat loss.

Energy act 2007
  • Manufacturers of hot water boilers must provide a
    means to adjust boiler output to actual heat load
    by 2012.
  • Exquisite Heat is the ideal indoor reset solution.

23
24
Thats fine if your buying a new boiler. What
about the rest of us? Can we do anything to
improve economy and comfort with our current
boiler?SureInstall Exquisite Heat to all
boilers.
25
Exquisite Heat
  • Adjusts heating supply temperatures according to
    Thermostat demand history (over time).

December 20, 2020

What happened?
  • A new heating philosophy for even comfort.
  • To satisfy Ideal Comfort Delivery during changing
    building heat loss conditions
  • Boiler supply is adjusted precisely every minute
    of the hour.
  • Reduced energy use provides a before tax
    return to the owner.

33
34
Efficiency
  • Reduced boiler piping standby heat loss for Hot
    water and Steam boilers.
  • Cooler boiler operation
  • Better air circulation at baseboard and radiators
    that are heated evenly.
  • Precise soft Comfort in all areas of the building.

34
35
We believe Exquisite Heat is the most precise
technology for reducing energy use, while
improving occupant comfort in homes and buildings
35
36
Thermostat activity is the accurate means for
detecting heat loss and comfort needs.Precise
adjustment of hot air, steam or hot water supply
provides ideal comfort for all heating systems.

37
Outdoor Reset Control
  • Most Apt. buildings have some kind of outdoor
    reset
  • Inaccurate weather, location, adjustment,
  • No measure of indoor comfort.
  • Most are misaligned with the building.
  • Difficult to regulate.
  • Poorly installed.

38
Outdoor reset control
  • Time lag from temp change to interior heat loss
  • Sensor is subject to wet, wind, placement.
  • Fixed curve assumption unrelated to building.
  • Buildings react to a combination of heat loss
    factors sunlight, wind, windows, insulation,
    structure, occupancy thermostat setting.
  • Over and Under heating.

  • Adjustable from central indoor thermostat.
  • Takes the indoor data and interprets it in to
  • High limit temperature for hot water boilers
  • Burner fire time for steam boilers.
  • Takes all environmental effects into immediate
    consideration at the thermostat, and adjusts
    heating supply to all rooms evenly.

41
All Heating Systems
  • Hydronic Radiant, Decentralized Steam
  • Hot Air Systems, Humidification,
  • Refrigeration, Steam Zone Valves,
  • Steam to Hydronic Heat Exchangers, Geo-Thermal

How Does It Work?
  • Would you like to go into the technical side of
    all this???

45
46
Assumption 1
  • Increased circulation delivers even comfort.

46
47
Assumption 2.
  • The closer the supply temperature is to the room
    temperature, the more fuel efficient the system.

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.

50
51
Constant
  • Ideal Thermostat Demand Ratio gives us a constant
    for comparison and adjustment.

51
52
Actual Thermostat Demand Ratio
  • The actual proportion of time a thermostat
    calls for comfortable heat in a given period of
    time. (60 minutes)
  • ADR

52
53
53
54
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

54
55
What information do we need?
  • Previous hour adjusted High Limit Temperature
    150 degrees F
  • Actual Demand Ratio.
  • Period of analysis 60 minutes (5-90 min)

55

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

57
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

57

63
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 60
  • 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.

63
64

65
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.

65
66
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.

66
67
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)

67
68
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.
