Small Space Heater?

Does the closet have a light? Maybe just try running a small che in the light socket. If not hang a hood securely for the che and have a small fan to move the air around? This amazon seller for example has 25w and bigger ches

When it comes to electric heating, don't worry about efficiency. Almost all electric heat is near or at 100%.

I just bought this small table-top heater for the small closet space where I keep my BP's. Just left it on low and it brought the room up the couple degrees I needed it to at night and it seems to stay there. I keep it off during the day, but if you need it to keep running you could. I thought about putting it on a thermostat, but on the low setting it really doesn't do anything but raise ambient air temp a bit. Has a higher setting as well.

I wouldn't advise using anything other than an oil filled heater (set as low as possible and controlled by a thermostat) in such a small, enclosed space. Because an oil filled heater works by convection, you will probably get decent air circulation without the addition of a fan. These heaters are very inexpensive, costing $40 - $80 for most models. I would suggest investing in one and setting it up in your closet with a thermostat (and doors) to see what kind of temperature gradient you get (low to high). That will determine whether you need to add a small fan for air circulation or vent the closet to improve air flow.

Hey guys! So I talked to my mom and we have decided to use the bathroom! That way I won't be heating a tiny closet. We don't hang out in the bathroom(Don't know why you would :weirdface) so it's okay if it's 82 degrees :)

Also we will have more snakes in the future so we arnt heating an entire bathroom just for one snake :P
