heat mat placement

[funnykooky]

hi all
probably a silly question,but where should i put the heatmat? on the outside or inside of the tank wall,currently i have it on the outside with bubble wrap behind it,thanks

Yep, you have it correct.
The ouside of the tank with a good layer of something insulating behind it to direct the heat into the tank, and on the side of the tank, not the bottom.
