Best I can tell its not possible without a step-up converter. I went down this road in the DIY forum, considering whether the 50W version of this heater could just run on 110v. My thinking was if the heater was made for 220v and you plugged it into an outlet with half the voltage, it would output half the wattage...but apparently the math actually works out to 1/4 the wattage.

Heater was around $20 shipped and converter was $12.50 (free shipping at amazon if you order $25 of stuff).

Could you possibly tell me how wide the heater is?
Thanks,

The diameter of the glass heating element is ~1/2", the diameter of the plastic ends is 15/16" and the length is 4"


A few pics from testing:

Power consumption of power converter without heater (or thermostat off):


Power consumption of power converter + heater when thermostat is on:


Temperature differential to room temp after 24 hours (generally achieved after ~12 hours):
