It is important for you to understand what it is that oil furnaces are in comparison to other types of furnaces out there. You should also understand the importance of BTUs. Most people do not know much about what either one of them are or what they do. You will find that the more that you know about them the better off you will be. With a good and basic knowledge of them you will be able to understand what to expect from them and how to tell if it is the right type of heating unit for you.
BTU stands for British Thermal Unit. It is a traditional unit of energy that equals out to be about the amount of energy that is needed for you to be able to heat a pound of water one degree. When it comes to scientific contexts, BTU is slowly becoming replaced by a unit of energy called SI. However, it is still used unofficially when it comes to metric countries that speak English. It is also the standard unit for air conditioning units that are sold in countries that do not speak English that use the metric system. However, in the United States, this term is used when heat value is described with fuels. It is also used to describe the power of cooling and heating systems with furnaces.
An oil furnace will use heating oil. This type of oil that is used is very similar to kerosene, a type of fuel that is used with portable lanterns and such. An oil furnace will use the oil to get the air that is inside of the furnace cabinet heated up. From there, the heat is then blown through the duct work with the help of a blower fan. The hot air is then blown into each of the rooms through the installed vents that are at the top of the wall. The cold air is then taken back to the furnace through registers that are on the floor or on the bottom of the wall.
Pros and Cons of Oil Furnaces
While gas furnaces are used more commonly, oil furnaces are much safer, especially when it comes to leaks. Oil is by far the cleanest type of fuel for a home heating furnace. It is however, the least efficient energy-wise. Oil is also one of the least expensive ways to heat up your home. This is because they are not sold by local utility companies, but by independent suppliers. Studies have also shown that there is very little that you will have to worry about maintenance wise when it comes to your oil furnace. You will simply need to worry about cleaning it once a year and changing out the filters twice a year. Oil furnaces are usually thought of as the most reliable types of furnaces around. In fact, if these types of furnaces are taken care of properly, then you can expect them to last as long as twenty years.
