What is the ambient temperature of the room. Theorectically, you dont need a single heater if you set your home thermostat at 80deg. On the other hand, if your tank is in a room at 60 deg, you might need a dozen.
If you need 700W of heating, get 4 - 200W instead of 2 -350W. The thing with heaters is that their bi-metal wears out redering the thermostat ineffective. The bi-metal is the thing that measures the temperature of the water. They will either stick on or off given time. It is better to have 1 200W sticking than 1 350W sticking.
I had my 100W heater stuck on in a 10 gallon. Raised the to 90Deg for 24 hours. Luckily, it was down the 65deg basement.
