Measuring The Heat We Use In Our House

I have been checking the heat meter every day. The meter measures how much heat we use, dad showed me how to put all my numbers that I got from the meter every day into a chart.

The average amount of heat we used is 47 kWh(kilowatt-hours) and in the past week we have used an average of 38.5.

As you may notice from the chart, some days we used a lot more heat than others, the reason is that we have not yet hooked up the thermostats so we just turn the pump on and off by hand, which means that if we forget, it stays on and we use more heat. On the first reading I took we were trying to heat up and dry out the house. Here is the chart.
