Answer:
Given that,
Power =1200W=1.2kWh
Time = 30 min / day × 30 days =0.5h×30= 15 h
Energy =Power×Time=1.2×15= 18kWh.

1200 W for 0.5 h can consume 1200* 0.5 =600 Wh = 0.6 kWh of energy per day of use.
April has 30 days.
Thersfore total energy consumption during this period = 0.6* 30 = 18 kWh.
It should be noted that this figure is the maximum energy consumption.
Actual energy consumption would be considerably less than this on account of the thermostat tripping when the set temperature is attained, and keeping the device off till it becomes cool enough to get switched on again.
