Oil Tank Winterization Made Easy

Oil Tank Winterization Made Easy

With extreme weather dominating all of the headlines right now, it can be easy to forget that winter is on the way. Now that fall is approaching, and heating season is starting up, it’s a great time to start preparing for the cold weather ahead. When it comes to oil tank winterization, there are a few easy things you can do to get ready.

Oil Additives

When the temperature drops to the freezing mark, heating oil begins to gel, and the wax within the oil can crystallize, clogging the lines. Consistently adding anti-gelling oil additives can help prevent this. This is by far the easiest and least costly preventative step you can take to help keep your oil lines from freezing. We offer a winter oil additive called SOS. One pint of SOS added each time you fill the tank helps prevent problems with gelled oil and frozen oil lines.

Check For Water In Your Tank

Water can enter your oil tank in a variety of ways: through the equipment, faulty fill caps, or even just in the form of condensation. If you have water in your tank already, its recommended to have the tank pumped out and the water removed. Water in your tank can lead to multiple problems, like rust that can damage your oil pump, ice that can cause blockages, and build-up of sludge and bacterial growth. These problems can be difficult to see, since tanks corrode from the inside out. A yearly tank inspection is an important part of oil tank winterization. Check fill and vent pipes, the tank body itself, and the lines. Another type of oil additive that we offer, called Sludgeban, can help reduce problems with sludge and other contaminants in the tank.

Move The Oil Filter Indoors

If located outside, the oil filter can collect a waxy build-up that can contribute to clogging in cold weather. Simply moving this filter to an indoor location close to the heater can help with frozen and clogged oil lines. When it comes to oil tank winterization, this is an often overlooked but important step.

Insulate Your Oil Lines

Wrapping any exposed oil lines can help prevent freezing. Be sure to use a water resistant material, and seal any seams in the insulation. For added protection, electric heat tape is available as well. Warming elements in the tape keep the temperature up.

Install An Electric Warming Blanket

These devices can be purchased online or at most home improvement stores. Made from weatherproof material such as silicon, they are easily installed on your tank and keep the oil warm and flowing in cold temperatures.

A properly winterized oil tank is a big part of keeping your house warm and cozy all winter long. 7 Oil Company is here to help you with the process. We can provide SOS winter additive at time of delivery, and our licensed and certified HVAC technicians and our full service Tank Division can help with some of the more involved projects listed above.
