You probably will need to run the pump 24 hours a day and the heater might be able to run only at night and many of them have a built in thermostat.

My pump will consume only 192 W per day. The pump has the power to pump up to 600 l (150 gal) per hour. That's three times the volume of my tank.
A ceramic heater would consume the same power in less than 30 minutes if it's a small one.
I don't mind the money for electricity - I want to see if this can done myself.
