Final chiller door claim

 

I've decided to tackle this one in a different way. Having got a ball park figure of 1 x 10^11J for the previous two claims, it should be the same here. 69 months is 5.75 years. 1 x 10^11 / 5.75 = 1.74 x 10^10 Joules per year. This is 48 million Joules per day. Now 1kWh = 3.6 million Joules. Hence this suggests the family home uses on average 13 kWh a day. Obviously houses will vary but the figure is not unrealistic.
