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?

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.

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).

Even Comfort

• Precise heating plant energy use allows for
  even comfort to everyone in the space.

Temperature vs. Thermostat

• The lower the radiator temperature the longer
  it will take the thermostat to sense the change.

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.

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.

Exqheat Indoor Reste control

• Comfort based room indoor sensor
• 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,

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
56
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
58
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

• Temperature Differential 1-20 degrees
• Low limit High Temp limit Temp. Differential

62

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.

68
