The key to comfort and reduced fuel use for all heating systems Exquisite Heat
Fixed temperature boiler control 4
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. May 28, 2014 6
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.
Hey Folks • At Exquisite Heat we believe your heating system should be comfortable first. • We believe you deserve good comfort at least energy expense.
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. $$$
Desired Solutions • Even out the comfort in all rooms • Shut the windows in overheated rooms • Keep complaints down • Higher humidity levels, less dry skin • Set the Thermostat lower for all rooms • Reduced running of the boiler, saves fuel • Get the heat out of the basement, and into the rooms… • Let’s lower those fuel bills $$$
WASTED $$$$$ • If your too hot or too cold, aren’t you wasting the • $ money $ you are already spending on Fuel for heating ?????
The Main Goal Precise comfort replacement for building heat loss. May 28, 2014 21

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
That’s 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.
Exquisite Heat Adjusts heating supply temperatures according to Thermostat demand history (over time). May 28, 2014 25

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
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
We believe Exquisite Heat is the most precise technology for reducing energy use, while improving occupant comfort in homes and buildings 35
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. May 28, 2014 36
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.
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. 38
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.
All Heating Systems • Hydronic Radiant, Decentralized Steam • Hot Air Systems, Humidification, • Refrigeration, Steam Zone Valves, • Steam to Hydronic Heat Exchangers, Geo-Thermal Systems, Solar Hydronic Hybrid Heat, • Fresh Air IAQ, Process Control, Navigation, 41

How Does It Work? • Would you like to go into the technical side of all this??? 45
Assumption 1 • Increased circulation delivers even comfort. 46
Assumption 2. • The closer the supply temperature is to the room temperature, the more fuel efficient the system. 47
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
