Well I kind of N rigged this portion of my build since i was kinda half assing my way through it, but I got a honeywell winter watchman thermostat controlled outlet and plugged it into an outlet I built on the inside and then plugged a lightbulb in to it

I ended up not using it because the liquid temperature never seemed to get too low what with the freak weather we had this winter so I unplugged it. (had 60 degree weather a couple days even in december and january)
