Hi everyone. I hope that your monitor heater is keeping you warm during this incredibly cold spell.
We get a lot of calls for frozen lines in weather like this. It is a good practice to make sure that there is no water in your tank when it is not below freezing. Some things that contribute to water problems are filling the tank yourself 5 or 10 gallons at a time. If you can afford it, it is better to have your tank filled by a local company. Also when placing a tank, make sure it is not under an eave where rain will drain on it often. There are also fuel treatments available from your kerosene provider that will help in dissipating water in the fuel. Changing the fuel filter annually will not prevent freeze ups but is recommended.
If you heat with a monitor heater or a laser heater, water in the fuel can really cause lots of problems. Even the tiniest amount of water that gets through to the igniter can cause it to burst and it is an expensive part to replace.
Hope this helps. Stay warm!!!
