I bought an oscilating space heater from Meijer for about $40 (free to me b/c I had a gift card). You can set it for a certain temperature like climate control or you can leave it on high or low. It came w/ a remote too so if you get hot/cold in the middle of the night, you can turn it off/on.

*Edit: Found it online, the brand is Lakso:
