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.

Symptoms Uneven comfort ( too warm-too cool)
Windows open - energy escapeFolks complain about comfort
Low humidity and dry skinWe raise the heat to warm cool spaces.
Excessive run times for boilerBasement too hot- waste of energy
High Fuel billsWHY?

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 $$$
