Does it matter where you place the heater of your tank? Is it better to place it in the middle, on the side, does it matter?

I know, sounds like a newbie question... although I've had my tank for 3 years, there's a lot I don't know and this forum seems to get more action.
 
I've seen people position heaters vertically, horizontally and on a diagonal, AFAIK it doesn't affect performance. I think as long as there's decent water flow around the heater and it's not touching the gravel/decorations you should be fine.
 
Place the heater near an outflow or somewhere that gets a lot of current to maximise the spread of heat through the tank. I have all my heaters placed under or near the outflows on my filters.
