The rising prices of fossil fuels (e.g. heating oil) boosts up the bills for heating homes and offices, so we see many people opting for wood burning stoves and boilers, open fires and switching to wood briquettes or other known as eco briquettes as more economical and eco friendly - green alternative for heating your home or office.
Wood briquettes as a fuel is great way to bring your heating cost down and at the same time preserve the environment as it is a eco friendly and CO2 neutral green fuel. Wood briquettes are cheaper because wood is cheaper than heating oil and other fossil fuels.
And many European Governments are about to introduce the carbon tax in order to cut the greenhouse gas emissions. All carbon based fuels will be taxed and thus their price will go up. Wood briquettes fuel is a new cheaper green alternative as EU Governments will encourage financially and will stimulate domestic and industrial users to switch to eco friendly alternatives and save money. Burning wood briquettes emits the same amount of CO2 as during the process of photosynthesis when wood as living plant absorbs CO2 from the air and consequently releases it back in the atmosphere. This is a cycle that repeats without increase of CO2 in the atmosphere.
Switching to wood burning stoves or boilers could be costly but savings will occur over a period of time using wood briquettes as a cheaper and economical fuel alternative. Besides that, Irish Government is providing energy grants for Irish homes willing to switch to green - renewable energy based heating systems.

Because wood briquettes are so dense - produces by compressing natural wood shavings and sawdust and have low moisture than normal wood, they are very efficient and heat output from them is usually 2 to 4 times higher than the ordinary firewood.
Besides being used in wood burning stoves, wood briquettes can be used in open fires. When the winter days are over you can even enjoy your BBQs fired with 100% natural wood briquettes, which are smokeless, very low in ash, easy to store and very clean for your household.

Eco Fuel Briquettes
All manufacturers of eco briquettes, or wood briquettes, sawdust briquettes and eco logs, pack and offer their produce, labelled with mysterious technical information: kcal / kg or kcal / kg. The average consumer does not have this terminology in their heads and most of them are used to convert the energy they can get from the electrical company, using kilowatt hour (kw h), because almost everyone knows how much a kw hr costs, purchased from the electrical companies.
However, what is the kilocalorie used on a pack of eco briquettes / wood briquettes or eco logs?
One kilocalorie is equal to 1000 calories.
Kcal / kg means that if it says on the label for example 4.23 kcal / kg and an eco briquette weighs 1 kilogram, the energy output from burning will be the equivalent of 4230 calories.
Is it a lot or too little?
The relationship between Calorie and Joule is:
1 cal = 4,184 J
1 J = 0,239 cal
1 J or one joule is a unit of energy.
3600000 J are equal to one kw h. So for example if 1 kw h of energy costs 0.20 EUR, then we can say that we pay the same for 3,600,000 joules of energy.
An average eco briquette has an energy efficiency of 4200 to 5300 kcal / kg or 4.2 to 5.3 mega calorie per kg, which is equivalent of between 4,200,000 to 5,300,000 calories per kilogram. We multiply calories by 4.18 and divide by 3,600,000 in order to arrive at kw h. If we start from mega calories per kg and want to convert to kw h, we multiply by 4.18 and divide by 3.6 or mega calories are multiplied by 1.61 to arrive at kw h.
By the above calculations an eco briquette with energy efficiency from 4.2 to 5.2 mega cal / kg gives out energy from the combustion from 4.87 to 5.72 kw h per kilogram. If one eco briquette weighs 2 kg, then the energy is twice as much.
This turned into cash at a price of 0.20 EUR for 1 kw h gives an energy of about 1 to 1.20 EUR.
