Is it likely for kerosene oil to freeze during the winter months?
No, the Cloud Point of Class C2 Kerosene to BS 2869 is minus 39 degrees C. Therefore, unless the location of an oil pipe is extremely exposed to wind chill, it is very unlikely for temperatures to plummet low enough within the British Isles to cause Class C2 Kerosene to freeze.
If a blocked oil supply pipe is encountered during the winter months, a more likely cause is that the oil line contains beads of water that have frozen, expanded and blocked the pipe.
Our best advice would be for an OFTEC Registered Technician to inspect the oil storage tank for the presence of water. If water is found, methods of extracting the water to prevent a reoccurrence can be looked into.
