[dvs] Thermostat setting

[Larry Menkes]

Jennifer,

It's been my experience that the most efficient setting varies with  
structure and heating/cooling systems. Technically speaking you can  
have as much as a thirty or thirty-five degree variation if the system  
can handle it. The contents can. You can have that much on a spring or  
fall day without htg. or cooling.

My hot water system isn't running as efficiently at the moment and  
it's slow to recover from my 6 degree setback.... I cheat a bit lately  
and go to four or five when it gets really cold at night. When I had  
forced air I could easily run a 10 degree setback and recover quickly  
in the morning. When out of the house I do about 8 degrees because  
coming in I'm dressed and a cool house seems warmer than when I get  
out from under my down comforter in the morning.
