Using a 110/120-volt heater (1,500 watts maximum) is fine for enclosed areas like garages, indoor work areas or outdoor spaces no larger than 5' x 5'. When heating larger areas, running a dedicated 110/120-volt circuit is not practical or economical. A 240-volt circuit will require the same amount of wiring, will heat substantially larger areas with greater comfort, and will simply require two spaces in the breaker panel, rather than one.
Can I run my Infratech heaters on only 120 volts of power?
