^ the problem with that i find is you are never 24/7 in a particular room, so what happens when say your at work for "x" amount of hours each day, you couldnt really leave your AC on and never turning it off
This, and I've also had ones before that are similar to what you use in a reptile tank, they're pads that stick under the tank and heat from below similar to what doomiedee mentioned.

I think you meant that you couldn't find one with a low enough wattage. Hydor makes 200W and 300W external heaters, but both are way too much for a 15G.
I was always told You can never have too many watts in a tank. More watts just means the heater is not on for nearly as long and does not have to work as hard.

this would be a good way to cook your fish. For safety reasons it is better to use multiple under wattage heaters in case one were to stick on. In your case just using a single heater, use what is rated for the 15 gallons at most. The internal filter and the light will also add heat to this tank.

5W per gallon is often considered the norm for smaller tanks, less for larger tanks. If you keep your house relatively warm all the time, I would suggest a 50W heater for your 15G. If the house is cool, 75W would be better.
Drawbacks of an oversized heater:
Greater temperature variance
Greater risk of overheating and killing your fish in event of the thermostat sticking on (not that uncommon, unfortunately)
Larger size (in-tank heaters)
More expensive
Most of them actually said it did nothing for increasing plant growth but did raise overall temperature. If you raised the temperature of the water below the gravels surface it would have an overall effect on the entire contents. Unless you think that the wateer below the gravels surface simply sits and does not mix with the rest of the contents.
Listen to Dan on wattage. Five watts per gallon is standard. Get a small enough heater and hide it inside a large hollow ornament if you need it to be invisible and the other options are not to your liking.
