No post (at least that I saw) claimed that setting the thermostat up
increased the rating of a standard residential hot air furnace.

Claiming that setting the thermostat higher than the desired temperature
will cause the room to reach that temperature faster is _exactly_equivalent_
to claiming that setting the thermostat higher than the desired temperature
will increase the output of the furnace. :-)

No one claimed that doing so would cause the room to reach temp sooner. I
was claiming (and maybe Ann was as well) that doing so would allow the
room to reach the desired temp with fewer "cycles" of off/on.

I'll try again to explain. If I want my house at 70, I might sent the
t-stat to 80. The furnace comes on, then cycles off as the air near the
t-stat is 80. As the heat in the air warms the rest of the stuff, its temp
drops, and the furnace cyles on. Once the system has done this a few time,
I reset the t-stat to 70.

If I had set it at 70 and left it there it would have reached equilibrium
at roughly the same time, but while it was doing so, the temp in the house
would have been 70 during the periods when the furnace was off, before it
kicks on again. I find this uncomfortble and would rather the chill was
gone while eq. temp is reached.
