A wood and oil furnace is becoming more and more popular today as people begin to find new ways to heat their homes and save money. With the way that the oil prices have risen in the last few years, adding another economical heat source is a good idea. When it comes to a wood and oil combination furnace there are some things to know about how to operate it correctly. One piece of information to be aware of is the best type of fuel to use in it. Here are some of the different types of wood and oil that are perfect for a combination furnace.

Wood Must be Seasoned

When you talk about the wood that is perfect for the wood burning portion of your combination furnace, the one thing that must remain constant, no matter what type of wood furnace you are using is that the wood must be seasoned. Wood that is just cut, which is called green, will damage your furnace by emitting a lot more creosote that seasoned wood. This type of wood is wood that has been sitting for at least one year. This way, most of the moisture has been dried out of the wood which helps the wood burn hotter, cleaner, and much more efficiently. Always begin your quest for finding the perfect burning material with seasoned wood.

Hard Wood Over Soft

Getting a fire started with soft kindling wood will make the process much easier. Burning for heat with soft woods is not very economical, nor is it safe. Softer wood is going to burn much faster than the harder woods. This will mean that you are going to be burning twice as much per year. Soft woods, because they burn up quickly leave a sticky residue on the chimney and inside of the burn chamber. This residue will build up over time causing problems, chimney fires, and possibly house fires.

Specific Hard Woods

For the most part, all wood gives off the same amount of energy when they are burned. The difference is in how long they last. Hard woods are much denser than soft woods so they carry a lot more burn time than a wood like pine, red cedar or spruce. For the best burning material you should use beech, hickory, red oak, elm and maple. There is going to be a little more cost per cord of wood, but you will not need as much for the year.

Processed Woods

Some combination wood and oil furnaces will burn processed woods like wood pellets. These are manufactured from saw dust, and wood chips. Great care must be used when choosing the type as some of the lower cost pellets contain a lot of glues and residues that cause chimney damage.

Oil Used for Heating

There are 6 classes of oils in use today and range from type 1 to 6. Types 5 and 6 are called residual fuel oils and are rarely used. However, it is Type 1 oil that is commonly used in home furnaces. It is a step below regular diesel fuel and is much like kerosene.
