How long would it take for an average heater to heat an 7 to 8 Gallon (or 20 to 30 Litre) tank to make it suitable for tropical fish?
Thanks.

Depends. Your best bet would be to get a thermometer. Both the suction cup glass and the stick on plastic kind are only a few dollars.
Even better (but not necessary) would be to find a heater with an automatic shutoff. I think Tetra makes a 25w one.
Finally, once you have a thermometer, you'll want to find out the ideal temperature for the kind of fish you have; and do your best to maintain that. If you aren't sure, let us know what you have and someone will have an answer for ya.
