6 6 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.

7 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.

13 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?

18 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… Let’s lower those fuel bills $$$

20 WASTED $$$$$ If your too hot or too cold, aren’t you wasting the $ money $ you are already spending on Fuel for heating ?????
