Ok, here is my question. How does keeping the temperature in your home lower your energy bill? Here is why I ask.
~I got new windows in the spring. good, much better, insulation. but keeping my temperature low has never been a strong point of mine; I like being able to be comfortable almost naked (if not so) in my house always.
~ So, assuming that there are no random energy leaks in a house (such as doors left open to the outside for hours, or wind gusts inside some how) the energy loss in the house should remain constant; for example, say 1 degree an hour.
~So, with the previous assumption unnegated, how does keeping the temperature lower help? the energy used after, say, 2 hours of operation (a drop of 2 degrees) should be the same whether its from 68-70 or if it is 76-78. the only difference would be if you have a regulating thermostat that drops the temperature when you are not there, in which case the energy expended would be more to raise the temperature back up. if its simple caloric calculations (I have radiant heat, so it literally is the energy to raise a given amount of water by a given amount of heat) then what am I missing when I hear that I should keep the temperature lower in the winter?! Why is this not making sense to me, someone help me out here!
