At what temperature do pipes freeze?

Pipes can freeze at 32F, but the risk zone starts at 20F outdoor temperature. Uninsulated pipes in exterior walls, crawl spaces, and garages are most vulnerable. Indoor pipes rarely freeze above 38F ambient temperature.

Is it safe to run a space heater on a smart plug?

Yes, if the heater draws under 1800W (15A at 120V) and the plug is rated for 15A. Check your heater's wattage label. Never use a smart plug with an extension cord or power strip—plug directly into a wall outlet.
