. Would there be any
downside to shutting the main water off?
Heat is forced hot air.


Only downside is if there was a leaking the heating system and the water ran
low. Otherwise the potential from water damage if there is a freeze up is
much more severe.

Smart thing would be to pay a neighbor to check the house every day or two
and look at getting some sort of remote alarm.
