FAQ: Why Does The Fuel In My Oil Tank Keep Gelling?

What causes sludge in oil tank?

Sludge is the result of water vapor in the air condensing inside of the tank upon changes in temperature. The water vapor pools into droplets on the tank’s interior, causing it to rust over time. Eventually, rust particles and water make their way to the bottom of the tank (water is heavier than oil).

How do you keep heating oil from freezing?

Preventing Your Heating Oil From Freezing

  1. You can choose to install your oil filter indoors. By doing this, you will prevent your filter from clogging with wax since indoor temperatures are warmer.
  2. Put insulation around your fuel lines.
  3. Try a blended heating oil.
  4. Create a shelter for your fuel oil tank.

How do you keep an outside oil tank from freezing?

Here are a few tips.

  1. Consider using blended heating oil. Blended heating has a lower freezing point than conventional fuel oils.
  2. Insulate the fuel lines. Use waterproof materials to insulate the whole fuel supply system.
  3. Keep the oil filters indoor. Keeping fuel filters indoors reduces the likelihood of clogging.

At what temp does heating oil gel?

Under normal circumstances, this occurs when temperatures reach approximately -9° or 16°F. The gel point or wax point is usually a few degrees below the cloud point, but again, the amount of time the oil remains exposed to colder temperatures is also a factor.

How do I stop sludge in my oil tank?

Preventing Tank Sludge

  1. Keep enough heating oil in your tank – An empty heating oil tank promotes condensation build-up on its walls, which accelerates the growth of sludge-forming bacteria.
  2. Get professional heating maintenance every year – A heating tune-up includes a filter change – a must for your heating oil system.

Can I put kerosene in my heating oil tank?

Kerosene is another acceptable alternative to home heating oil of the type known as No. 2, a designation that indicates its weight and grade. Almost all home heating oil is No. 2; if you happen to burn a different weight of oil, diesel may not be an acceptable substitute.

Can heating oil lines freeze?

Like water, heating oil begins to freeze when temperatures drop (in heating oil’s case, that point is 16°F) – but unlike water, which freezes into a solid, heating oil simply thickens into a kind of waxy sludge. This thickening is commonly called gelling.

What temperature does #2 heating oil freeze?

Why is My Heating Oil Frozen? The storage of #2 heating oil usually goes without problems, but it can freeze if the temperature gets too low. The fuel begins to appear cloudy at around 35 degrees Fahrenheit. However, the altered appearance makes no impact on the oil’s ability to flow in your heating system.

Can fuel oil gel?

As for heating oil, yes, it certainly can—though not exactly in the way most of us are used to. When heating oil is exposed to low enough temperatures, the paraffin content of the oil will begin to gel.

How do you heat up fuel oil?

Normally the heating is by way of steam produced by an oil-fired boiler and passed through coils inside the oil tank. Other ways to heat the fuel tanks are by using thermal oil. It also utilizes an oil fired boiler that heats the thermal oil, which is circulated through coils inside the tank by a pump.

What temp does kerosene freeze?

The freeze point of kerosene depends on grade, with commercial aviation fuel standardized at −47 °C (−53 °F). 1-K-grade kerosene freezes around −40 °C (−40 °F, 233 K).

Does cold weather affect heating oil?

A reputable heating fuel oil distributor will help you reduce your oil consumption. Cold weather can affect oil production negatively if temperatures drop low enough. Crude oil has a freezing point of between -40 and -60 degrees Fahrenheit. Heating oil demand is seasonal.

What is the pour point of home heating oil?

Pour Point This is usually 5ºF above the temperature at which the oil thickens into a solid mass. The ASTM D396 Standard lists the maximum pour point at 20°F. Obviously, if this range is exceeded, there could be problems with oil flow in certain cold ambient applications.

Does heating oil go bad?

The good news is that home heating oil should last 18 to 24 months, as long as effective additives were mixed with it upon delivery. 2 heating oil, is essentially the same product as diesel fuel, except diesel has additives intended to boost effectiveness in motor vehicle engines during cold weather.
