BTU = British Thermal Unit. A BTU is the amount of energy required to raise one pound of water one degree fahrenheit. Below are some BTU equivalents of various fuels for comparison:
1 gallon of #2 oil = 140,000 BTU
1 barrel of crude oil = 42 US gallons, 5.80 million BTU
1 gallon of LP gas=91,500 BTU
1 gallon of Kerosene=135,000 BTU
1 cubic foot LP gas = 2,550 BTU
1 cubic foot natural gas = 1,000 BTU
1 KWH electricity= 3,413 BTU
1 therm. natural gas = 100,000 BTU
1,000 BTU = 1 lb of steam
1 ton of coal = 28,000,000 BTU
1 cord of firewood *20,000,000 BTU
1 pound of firewood *8,000 BTU
*Firewood BTU based on air dried wood logs and is a subjective average of common US wood species.
Physical units reflect measures of distances, areas, volumes, heights, weights, mass, force, impulse and energy. Different types of energy are measured by different physical units: barrels or gallons for petroleum; cubic feet for natural gas; tons for coal; kilowatt-hours for electricity. To compare different fuels, we need to convert the measurements to the same units. Some popular units for comparing energy include: Btu, barrels of oil equivalents, metric tons of oil equivalents, metric tons of coal equivalents. In the United States, the British Thermal Unit (Btu), a measure of heat energy, is the most commonly used unit for comparing fuels. Since energy used in different countries comes from different places, the Btu content of fuels varies slightly from country to country. The Btu content provided below and used in the energy calculator reflect the average energy contents for fuels consumed in the United States.
EXAMPLES OF CONVERTING TO BTU
You have a natural gas furnace in your home that used 81,300 cubic feet of natural gas for heating last winter. Your neighbor, with the identical house, has an oil furnace that used 584 gallons of heating oil last winter. To determine which home used more energy for heating, you can convert the natural gas and heating oil consumption figures into Btu, as follows:
Natural Gas: 81,300 cubic feet
(your house) x 1,031 Btu
cubic foot = 83,820,300 Btu
Heating Oil: 584 gallons
(neighbor's house)
x 139,000 Btu gallon = 81,176,000 Btu
In the example above, you used more energy to heat your house!

Bored with the traditional heaters? Heating is absolutely essential for countries like the United Kingdom, where the temperature dips below freezing point. Heating options are quite extensive and may include electric or non-electric heaters. Non-electric heaters are those that run on oil, kerosene or wood, while the electric ones obviously run on electricity. In the electric range you will be able to find different models of heaters. There are two types of electric heaters; convection and fan heating units. Oil filled radiators are convection units while a garage fan heater is a fan heating unit.
Convection heaters use air currents near the device to heat and rotate the air. This type of heater is ideal for those people who want background heat in their house. Fan heaters use their built-in fans to heat air as it passes through them. The different types of heaters are panel heaters, radiant heaters, or wall heaters. The type of heating also varies according to use. Domestic and commercial heating needs are fulfilled by different types of heaters.
Panel heaters are ideal for heating your home, room, cabinet, or office. They are energy efficient and provide good comfort. Radiant heaters on the other hand distribute the heat evenly by heating individual objects.
Wall heaters are more appropriate when you want to heat a small space or just one room. They can be found in three different models; electric, propane and gas heaters. The Electric model is the easiest to operate amongst these three, as you just plug them in and it starts heating. As opposed to propane and gas heaters, which need propane and gas lines, and may therefore be costlier to operate. However, the gas heaters are more environmentally friendly.
There are two ways of installing these heaters on the walls. One type uses hooks and fasteners to attach the heater to the wall and then its energy source is attached to it. A major advantage of this type of heater is that they can be easily moved from one place to another and therefore gives you greater mobility with them. The second type of heater is placed inside the wall, but not when the house is build. The price may range from 0 or more, however it greatly depends on the brand that you are buying.
These heaters are a convenient way to heat your house. They give you more flexibility as you can place them wherever you want to. Installing and maintaining other larger heating systems may obviously be quite expensive. It also saves your precious space, which can be utilised for other more productive purposes. Nowadays, you can find stylish designs and amazing colours meant to suit your tastes. A good wall heater will not only give you warmth and comfort, but also enhance the look of your house.
The VF20KBLUELP is a propane fired, vent free, blue flame heater that produces 20,000 BTU's of efficient, comfortable heat. This safe, clean-burning heater has a five setting heat control, low oxygen shut off sensor and burns 99.9% efficient. This unit does not require electricity and is easily installed as a wall mount unit or as a free standing unit with the included feet kit. Battery powered spark igniter (AA battery included), and blower fan for increased air circulation. This CSA certified heater will heat up to 600 square feet and comes with a limited two year warranty.
There are many different types of heating oil. In general the different types are fairly similar; though there are a few key differences. I will be listing in the following paragraphs what these types are as well as some details about how they are used. Unfortunately nearly all types of heating oil are bad for the environment in some way. Each class is based on Boiling points. The points range from 175-600 degree C. Prices are normally cheaper if the class level is lower on the scale.
The first class that I have for you to look at would be the first class heating oils. This is more like the gas you run in your car or kerosene that you use for heat in your house. It is not bad really on the environment unless it is used in high amounts or in a lot of applications like the 50million cars we have out on the streets at one time.
The second class that this will cover is the heating oils that you would use in large trucks or commercial vehicles. It is known as diesel and it is not that hard on our environment but it still leads to pollution when burned. Diesel is commonly used in trucks and large vehicles; though recently many smaller vehicles have begun using it as well.
The third class heating oils are called distillate fuel oil; today we don't not use much of this at all simply because it is in the high numbers and we don't have much need them anymore. Distillate fuel oil has essentially been overpowered by newer fuel technologies
The fourth class is typical blended fuel; it is a blend between Distillate and residual fuel oils. This class could be known as many things that we use today ranging from diesel to distillate or even sometimes residual fuel oil. You can use this class for many things such as: heating, cars, trucks, cooking and much more.
The fifth class is called the Residual fuel oil. The number five class is a mix of 75-80% of class number 6 oils and then it is 25-20% of the class number 2 oils together. It is not the most efficient type of oil but it does well enough for most uses.
The sixth class that I have for you is heavy fuel oil. It has little of class two in it but the rest is just heavy not good for much of anything other then killing the world. This level burns faster than all other oil types and it also leaves behind more heavy residue on the things that it touches; as a result heavy fuel oils are quite bad for the environment.
To sum this all up for you is that there are six different classes of heating oils. The lower in level they are the better they are for most uses; lower numbered oils are also generally cheaper. The higher the level the most costly it is for you to use and the more damage it does to the environment.
