The rule for marine is 2 watts per gallon minimum. Submersible is better, 'cause it's more reliable. There are new ones that are carbon fiber instead of glass. I would go for these, they automatically switch off if taken out of the water -- and no glass to crack or break.
20 Watt, carbon fiber. Set it to a temp that you can keep constant. If water begins to heat up too much, freeze water in a coke bottle and float it in the tank to lower.

I would go with a heater that is recommended for a 20 gallon tank that is completely submersible. The reason being is that the smaller the heater, the longer it has to stay on to bring the tank to the desired temperature. Any brand should work just fine. Also keep in mind that you need to have adequate circulation. If the water is not moving around you will get a warm spot in your tank. It is like adding warm water to the bath tub. You move it around to make the temperature even.

This is one area where I recommend not skimping out. Spend the money on a high quality brand that will regulate the temperature well and won't fizzle out, or even worse, stay on and boil the tank. Submersible makes it easier to work with too, and is always the best alternative. For a 10 gallon 50 watts is plenty.
As far as brands go, well, if you spend the money you should be alright. I stick to the tried and faithful - Ebo Jagr.

One of the heaters that can be totally submerged is nice,you don't have to be so concerned about water level in the tank. The wattage depends on the average temperature in the fish room. If it's always warm, (over 72F) then 4 or 5 watts per gallon is fine. If the temperature flucuates lower than 70F then go with 7 to 10 watts per gallon. Hope this helps. PeeTee

Ive had the same Guardian heater in my tank since starting it three years ago. They make them for all size tank, just get the one that is marked for -up to 10 gallons. I like the Guardian brand because it it completely submersible and not made of glass. It feels safer to me that it wont crack or shatter in the tank.

It all depends on the type of fish you have. Some types. like goldfish are cold water fish. If you have tropicals, any old heater for a 10 to 20 gal tank will work. I would recommend a side hanging type this way you don't have to put your hands inside the tank to adjust the temperature. Also put a stick on thermometer to the glass so you can constantly see the temp.

The standard heater wattage for 10 gallons is 50 watts. Marineland's visitherm stealth is my personal favorite. It runs around 10-15 bucks.
