What size heater is required for a 180lt aquarium?

"I would use two 200 watt heater thermostat units. Both set at the same temperature and one each end of the tank."Initial question is seriously lacking in details to get a complete answer.180 litres is approx 47 US gallons, or 40 IMP Gallons,Some details neededWhat is average temperature in room with aquariumWhat is desired temperature of water in aquariumThe difference between the two numbers is the amount of temp increase you need. With that number, and the size of tank, you can get the recommended size of heater. In your case, 50US Gallon tank needing water temp raised by 10 degrees F would require a single 150 watt heater. If your fish tank is not just 4 glass walls with gravel on bottom, you would need to supply the following information to get a proper dual heater setup.What filter system is being usedWhere are intake and discharge ports locatedIs there an air wall or air diffuser being usedIs there some structure in place like a rock wall, or rock pileDoes tank have direct sun lightHow large is largest fish, and how many fish and/or animalsGenerally, you would place heaters where the fish cannot touch or get trapped by the heater(s). Heater should be placed near something that is creating flow, or currents. For example, if you have an air wall, heater should go under that device, to take advantage of the current created by the air wall. Same idea for filter intake. Heating water, then having filter take that heated water and running it through filter media, and then returned to the tank as far from the intake as you can.Actually that opinion also suggests that your intake and discharge ports on the heater unit be placed af far away as possible.
