Done that !
Only happened once .
Got up and switched tank.
When it gets time to run furnace and its that cold both tanks are topped off before fall .
30 lbs will run a months worth of weekends.
I've been around my tanks enough to know when there low-ish.
I'll also turn the full one for the night if its that low.
