What i did was buy an old glass door refrigirator.

Wire it up with 2 heat cables, put those into a pulse stat, put the pulse stat into a thermostat (just incase either one of them "fails").
Bought a small fan that i plugged in and .... i was done

So far it works fine, only downside it that it currently sits near a window, which in the morning has full SUN... so when this clutch hatches i will move it to a different room and not close to where sun can affect it.
