Whenever the temperature at your home or business is expected to drop below 32°F for longer than a few days, it is important to make sure your outside oil lines and heating tanks are well protected.
Oil will not freeze, but tanks and oil lines that are located outside a home or in an unheated space could freeze and lose their heat. The main reason for this is, the oil in the lines will get cloudy and then become gelled or waxed, preventing it from flowing. When this happens, you will lose your heat.
There are a few steps you can take to make sure you are prepared for a prolonged cold spell. Start by adding a fuel oil treatment to help prevent the oil from gelling or waxing. After adding a fuel oil treatment, the simplest and least expensive solution is to insulate the piping and fittings at the tank with pipe insulation and a strong tape, like duct tape. This step will need to be done before a problem occurs and the tank freezes, but is an easy way to winterize your tank before the cold snap hits.
Protecting your tank and the oil lines from freezing may be accomplished by wrapping the exposed areas in insulation and heat tape. Should the lines already be frozen, you will need to thaw them with sustained heat until they begin flowing again—then apply the insulation and tape. Follow the instructions carefully or call a Drain King professional plumber to avoid overheating the pipes.
We also recommend using only a single line extending from the tank that stores the oil rather than a two-pipe system. The single oil line will keep the oil warmer and will have less time away from the heat exchange.
Another option for an outside tank is to use kerosene instead of heating oil. Kerosene will store at colder temperatures and will not need any additives or treatments to keep the lines from clogging. This is a headache-free solution. While kerosene is more expensive, it may be a more suitable option if you live in a region where it stays cold for long periods of time and if building a shed or protecting the unit from the elements is not an option.
