First you need some enriched uranium. Then you place it in the tank.

Increasing the pressure would make it boil, but not heat it. That is my only scientific idea.
Some other thoughts…
blow on it (breath is 98.6 degrees…hopefully)
put it in a warm room in the house…such as an attic that has no ac
put it behind the fridge? i know this is kinda electricity…but more indirect. the fridge kicks out hot air to keep it cool inside.
well hope these ideas help!

ps…i dont think i would stir or dump random exothermic elements into my fishtank….i do not believe your poor fishies would enjoy that very much~! lol

Geothermal – if you live in Iceland.

Heat is a by-product of using energy…you’ve ruled out the easiest.

Stirring the water will raise the temperature…burning calories with your body and transferring the heat will work…a Fresnel lens would probably warm it up enough with just the ambient light in your room.

im sure theres some element that would have a chemical reaction causing a rise in temperature. not sure which element and not sure if it would be safe to drink but that wasn’t part of the question.

so i’d take a bit of every element of the table and drop them into a glass of water until i got the reaction i wanted.

microwaves or does that count as the sun since it is light?
