The heating load is basically the Heat Loss Coefficient $($Btu$/($hr X F$))$ multiplied by the difference in temperature across the object. It describes how much heat moves through the object each hour based on the difference in temperature and other factors. What would be the heating load created across a floor over an unconditioned crawl space if the floor measures $24$ feet in width and $51$ feet in length, the R$-$value of the floor is $5,$ the temperature in the crawl space is $46$ degrees and the temperature in the house is $74$ degrees?
