I think it would work fine. I use a larger one, in my spare bedroom. Works great. The idea is to find one that can run "all the time", but be controlled by an external controller. If the switch is "instant on" (ie, the rocker switch doesn't stay in the "ON" position), it will turn itself off for good after one cycle. You don't want that. You need one that STAYS on (the switch, I mean) even when the power is turned off.
