How much does it cost to run a ceramic space heater?

At 1,500W and average US electricity rates ($0.12/kWh), running a ceramic heater costs about $0.18 per hour or roughly $1.44 for an 8-hour day. Using a thermostat or ECO mode reduces actual runtime and cost since the element cycles on and off.

Can I leave a ceramic heater on all night?

It's generally not recommended. While modern ceramic heaters have safety features, the safest overnight options are oil filled radiators, which have lower surface temperatures and retain heat. If you must use a ceramic heater overnight, ensure it has a thermostat, tip-over protection, and overheat shutoff.
