Assuming you are in the U.S. you'll probably need a power supply for 110v (typical wall outlet), unless you have access to 220v which these units do like more and run more efficiently on (220v is what we typically use for the dryer, electric stove, and large equipment)

They do put out a ton of heat and noise. If you need heat for a chicken coop then this is a viable option. Look up some videos on YouTube to make a heater out of one of these.
