How much heat does a pipe lose?
Assuming that your hot water is 120°F and the air surrounding the pipe is 52°F you will lose 45 Btu (British Thermal Units) per hour per foot. 1 If you use the 125-foot assumption, this means you will lose 49,275,000 Btu, while using my 50 foot assumption you would only lose 19,710,000 Btu. One therm, the common unit of measure for natural gas, in the US is equivalent to 100,000 Btu, so you will burn through an extra 493 therms (or 197 using my assumptions), costing you an extra $400 per year (or $160 using my assumptions).
