No, you won't. Not unless you've discovered some new laws of
thermodynamics.

it is called heat transfer. more heat in air at 80 will put more heat into
the walls, getting them up to 70 faster. You won't save energy, you will
save time. But, the heat loss out the windows will be greater with a temp
up to 80.

Any difference there might be would be far too small to be noticed. Were you
imagining that heat transfer at 80F is 14% faster than at 70F? Doesn't work
that way. Use absolute temperatures.
