Biomass refers to any material produced by living organisms (such as wood and other forest products, crop residues, animal wastes, wastes of food industry, etc.) and can be used as fuel for energy production. 

This energy which is bound in vegetable substances comes from the sun.  During the process of photosynthesis, plants transform solar energy into biomass. The life forms engage that energy with their food and store a part of it. This energy gives final biomass after treatment and use. It is a renewable energy source because it actually stores solar enegy blocked by plants during photosynthesis.


The advantages of biomass include: 

  • As a raw material it can be found everywhere on the planet and in abundance. 
  • The production and use does not pollute the environment with toxic substances, since the products of combustion are basically water and CO2. 
  • The cost of the necessary facilities for the treatment is amortized in a short period of time. 
  • It solves the problem of litter in towns, even turning it into a profitable investment. 
  • Increases jobs and stimulates rural economic life, the energy/ alternative crops (various kinds rape, sorghum, reed). 
  • The minimal presence of sulfur in biomass contributes significantly to reducing emissions of sulfur dioxide (SO2), which is responsible for acid rain. 

In economic and national level, where the biomass is domestic source of energy, the exploitation of energy contributes significantly to reducing dependence on imported fuels and improve the trade balance in securing energy supply and saving foreign exchange.


Fireplaces are environmentally friendly and completely safe, the closed fireproof glass door allows the woods to low burning and may continue burning while you are away. Moreover due to the qualitative combustion is causing less emissions of smoke from the chimney.


  1. Αerothermal fireplaces
  2. Fireplaces as radiators

  Αerothermal fireplaces:

There is confusion and misinformation that energy source is one that has a built in tube or fan.  Huge mistake! Neither the balloon or the fan make a fireplace energy saver.

They produce hot air which can be used to heat one or more rooms. The air can exit by either natural circulation or forced circulation, ie fan. 

It can be done also by distribution of air to all rooms with the use of a special fan distribution.


 Fireplaces as radiators

Water Fireplaces as radiators

Fireplaces radiators main function is to channeling the energy produced by the combustion of fuel in the water. Water is transported by means of a pump radiators. 

They have excellent thermal performance and are well designed to burn wood with ecological and economic way. 

The operation is similar to that of normal fireplaces, regarding the lighting, use and maintenance. The hot water is sent by means of pumps in the heating system and offers uniform heat distribution at different places of residence. 

The fireplaces radiators can be used as the sole heating source in larger areas up to 200m2. 

The function can be either independent or complementary to central heating boiler combined with oil.


    Wood boilers are installed in the boiler room and does not have to limit the maximum power that fireplaces and stoves have, and can comfortably heat huge spaces. 

    In wood boilers we meet two categories. Ordinary boilers and modern wood gasification boilers.

    In simple boilers, combustion is not controlled or partially controlled by an air damper which opens and closes according to the temperature of the boiler, and controlling a degree of the oxygen that generates the combustion space and hence the intensity of combustion of the wood. The temperature of water in the radiator can not  be precisely controlled so some times  the temperature in the room is more than we ask.

    In gasification boilers or otherwise reverse flame boilers burning wood is done in two stages. 

    At first the wood is burned in the upper chamber by the method of reverse flame. The gases produced in the first chamber are guided below the second chamber where they are burned in a ceramic component in a very high temperature, providing 92% yield. 

    A fan sends oxygen or completely closes the provision of the tightly closed combustion area. It controlls the burning of wood in accordance with the demand that exists from the thermostat and the temperature is controlled so as not sufficiently escape from the desired limits or almost closed when there is no demand. 

    Since the combustion takes place with a high degree of efficiency of the combustion residues that ashes are very few in amount relative to the simple burning avoiding in this way the daily cleaning of the boiler.


    Pellet boilers are very economical to use and easy to be installed. The fuel material (pellet) is stored in a tank (silo) and is guided automatically into the combustion chamber by means of a screw which promotes the amount needed to yield the desired temperature. The burning pellet, made with the help of a modern boiler pellet, warm water boiler later through mains will be released in colleges.

    Pellet Advantages

    Practical by be transporting packaged and can be used with an automatic dispenser for feeding the fire.

    Standard well developed technical specifications for maximum performance (density> 650kg / m³, humidity <10%, ash 1% max.) and can be stored anywhere without changing, since it is protected by the packaging.

    Efficient because of constant density, low moisture, low cost transportation and storage (calculated that one pound equals 5kWh).

    Eco-friendly to create the pellets need not be cut because trees produced from discarded or recyclable timber and a perfect combustion (minimal moisture content and any chemicals) eliminates the quantity of produced ash.

    Reduces forest residues burning pellets helps to substantially reduce forest residues from timber and furniture industry.

    Pure Burning  pellets do not emit dangerous gases during combustion due to the absence of chemicals in the production process.

    Low cost pellets are cheaper than gas and electricity.
