Another economical solution for heating, at least in relation to oil, are wood pellet burners. So already many have already replaced their traditional burner with a new one, which burns this new, environmentally friendly fuel, wood pellets.
Pellet burners are characterized by particularly high efficiencies, do not pollute the environment and depending on the model can produce between 10,000 and 60,000 Btu per hour. Because these burners burn wood residues so efficiently, there is no need for a regular chimney, as the exhaust of the fumes can be done through a small hole in the wall from a pipe that ends outside, this pipe consists of a stainless steel inner and an aluminum exterior. Pellet burners can use an existing chimney, but it usually needs to be modified in order to run the pipe through which the smoke will be extracted.
Automated operation
Although in essence they burn wood, even in a processed form, this does not mean that they are a "traditional" proposition, which is characterized by a lack of technological superiority. Pellet burners rely on complex computers and electronic circuit boards to determine how much pellet fuel to burn. Most models have at least two combustion modes and some models use thermostats to control this combustion.
Feeding the burners and burning the pellets
One of the key advantages of pellet burners is that they don't need refueling as often as other wood-burning appliances. Depending on the device and the heating needs, the supply with pellets varies from once a day to once a week depending on the burner model and your heating needs. To do the refueling, the pellets are simply placed in a hopper, which holds between 15 and 60 kg, and from there a mechanism transports them inside the burner. Burning pellets in the burner is usually convenient, neat and safe and the pellets are compressed and bagged so you can have clean and easy storage for convenient management. In addition, the outside of the burner is not used to radiate heat and remains relatively cool preventing you from getting accidentally burned if you touch it accidentally.
Cost
Most pellet burners cost from €1,000 to €3,000. If you're comparing the price of a pellet burner to a gas-fired or other heat-generating device, it's a good idea to compare the total installation costs of the different systems. If the pellet burner does not need a chimney, then the cost of the whole system may be less than that of another.
Regarding the price of pellets as fuel, this is definitely more advantageous than the equivalent of oil!
