Why pay for something that you don't use?

How cold does a house get with no heat, relative to the outside? Will it
eventually cool to match (with a bit of time-lag) the outside air, or will
it always keep a few degrees above whatever the outside air's doing?

It would probably hold some heat from absorbing sunlight, but I
wouldn't count on it to keep the pipes from bursting. If it gets
below 20 degrees F, you need to either heat the house or drain the
plumbing.
