To save on heating cost, the owner of a greenhouse keeps 660kg of water around in barrels. During a winter day the water is heated by the sun to 10.0 degrees C, during the night the water freezes into ice at 0.00 degrees C in nine hours. What is the minimum ampere rating of an electric heating system (240V) that would provide the same heating effect as the water does?
