Space Heater FAQs : Troubleshooting
Some heaters have elements that glow red when generating heat. If you see a red glow from the unit it is normal.
It is recommended that heaters not share the outlet or circuit with other electrical devices.Heaters can use up to 1500 watts and 12.5 Amps on the highest setting. The average home uses 15 Amp circuit breakers, which only allows 2.5 additional amps to be used before the maximum limit is reached.
