How much 5 liter water will be cooled with a Peltier module

I am using a single Peltier module to check it is efficiency of cooling a water, As I have set the entire setup of Peltier module with a heat sink with a fan a aluminium pillow block with a water pump in the Styrofoam container having 5 liter of water, I ran this setup for 2 hour and the water temperature reaches from 31.8 Celsius to 27.6 Celsius which is a difference of 4.2 Celsius, As the peltier module is using 12.5 dc amp which is equivalent to 150 wattage in 220v it consumes around 0.3 units to perform this task, in my opinion this Peltier will reach up to 22 Celsius if keep working for 6 hours, which is good thing because this Peltier is working really good in cooling the water.
