How to Prevent Fuel Oil for an Oil Furnace from Freezing

"Home Heating Oil" also called "# 2 fuel oil" (or simply "Number 2 Oil") is a fuel used to heat buildings, homes and water. This heating method is very popular in the New England area. The #2 fuel oils (both clear diesel fuel and dyed home heating oil) do not freeze but rather "gel" or thicken to a soft wax. This begins to occur when temperatures drop below 32F, when the fuel starts to become "cloudy" (but still flows readily). As temperatures continue to drop (20F to 15F), wax or paraffin in the fuel begins to crystallize and separates from the oil. These crystals collect on filter surfaces and cling to the interior walls of the fuel lines that are subjected to these low temperatures. Below are some tips to help prevent this from happening.
