I'm going to guess and say it's some kind of oil??

OIL!?!?! from the plastic of the heater?

A lot of people have this problem, it's perfectly normal. Although, if you don't like the way it looks...

it's fine, I've had one of these heaters set up for over a year and it's always had bubbles on it. Fish are all ok and the heater works fine.

Usually happends do me when doing and heavy water change o when setting up a new tank. Don't exactly know why this happends but it happends on almost every tank I have owned.

The reason it happens is because dissolved gasses are less soluble at higher temperatures. It just means that the tank is well oxygenated.

my heaters get bublbles on them to.. ive also had glasses of water with bubbles on the inside walls.. so i think its fine

when water gets hot, it starts to boil, but not hot enough to do any damage but enough to make the bubbles
