Tumwater's Propane Supply FAQs
The degree day system was developed by heating engineers who wanted a method to relate daily temperature to the demand for fuel to heat buildings. To calculate the heating degree days value for a particular day, Acme Fuel will find the day’s average temperature by adding the day’s high and low temperatures and then divide by two. If the number is above 65, there are no heating degree day value for that day. If the number is less than 65, we will subtract it from 65 to find the number of heating degree days. For example, if the day’s high temperature is 60 and the low is 40, the average temperature is 50 degrees. 65 minus 50 equals 15 heating degree days for that day.
The efficiency levels of oil heat systems can exceed 95 percent. For every gallon of oil burned 138,000 BTU’s of energy are released.
To heat the home a furnace uses air and a boiler uses water. A furnace uses the flame from the oil burner to heat air, which is distributed throughout the house. A boiler uses the flame to heat water that is either sent around the house in pipes to radiators or is sent to a fan coil unit that heats air.
