Heater burned my anemone

[mynewtank]

Overnight, my anemone had parked himself next to the heater.  I've since moved it but it looks like some damage has been done.  A small area looks dark and retracted.  Will this heal and can it get infected or have any long term effects?

Pics would help. 

 

What part of the anemone is damaged? Tentacles should recover fine unless it gets infected, disk is worse, foot is especially bad. Any wound can get infected, on anything.
