In electric two options are:
1). Baseboard heat
2). Plug-in heater with an outlet
Both have thermostats. I might lean toward the plug-in heater if the baseboard heater might get wet. You could keep the baseboard heater against the house. The baseboard heater is silent where the plug-in heater has a fan that might be irritating with quiet conversation. I've used both to heat areas the size of a 2-car garage.
