When winter comes along with the cold, you have to heat the house, for this we have several options such as boilers or pellet stoves. In the city, the most normal thing is to use gas, but in the towns or in not-so-centralized places, such as more remote urbanizations of the urban nucleus, we can find that there is no gas installation.
In these cases there are several options at our disposal, until not long ago electricity, firewood or diesel were our only options.
Since a time ago, pellet stoves are spreading more and more as a substitute for the classic fireplace or wood stove.
Pellet stoves and boilers How do they work?
As we have commented before pellet stoves have been a real revolution in heating systems. This is an economic and energy improvement.
Biomass stoves and boilers use as fuel a 100% renewable element of low CO2 emission commonly known as pellets. There are different types according to the needs in each case, let's see some of them.
These stoves are perfect for heating wide and open spaces without much distribution of rooms, perfectly supplies a wood stove or fireplace.
The air stoves work by means of an adjustable combustion flame and with a turbine that is also usually adjustable which expels the hot air to the room. They can have a programmable thermostat.
Also, also they can work with the combustion of other materials with almond shells or olive bones Depending on each model.
Stoves of ductile pellets
These stoves, apart from generating heat such as air heaters, are prepared to supply hot air to other rooms in the house. Through a second fan they can supply hot air to the house circuit independently.
Hydro stove or Pellet thermostat
The main advantage and difference of the thermo stoves or pellet hydrosumbers, is that they are capable of feed water circuits for radiators or underfloor heating. It is also possible to connect them in parallel with other types of heating systems such as gas or oil boilers, thus complementing the two systems according to the requirements of each moment.
The main difference between the different types of biomass stoves and a boiler is that the boilers are also designed to supply your house with sanitary water and heating circuits and not exclusively to generate heat by combustion.
What are the pellets?
The pellet is a 100% material from natural materials formed by sawdust and pressed shavings from industrial waste. This material is little polluting and has a great calorific value.
This natural fuel is made from dry sawdust without any added material, since the lignin itself that contains the remains of wood serves as a binder.
The pellets are formed by subjecting high pressure to the sawdust, thus obtaining these cylindrical shaped pieces of about 2 cm able to concentrate great calorific value.
How many kilos of pellets does a boiler consume per day?
This will depend entirely on the type of stove or boiler we have and how much we use it, so the kilos of pellets consumed by a boiler per day It is totally subject to our level of heat consumption.
What we can say more accurately is that:
- 2 kg of pellets equals 1 liter of diesel.
- 1 kg of pellets generates 5 Kw / h of electrical energy.
Price of pellets per kilo
As in all products there are different qualities, it can also be said that the average price of the kilo is given when we buy by tons, since if we buy loose bags, which are usually 15 kg, the price can be doubled or even more.
Do not worry, the price of pellets will be much clearer seeing the following equivalence tables.
- 1 liter of diesel ——- → generates 8.800 kcal.
- 1 m3 of natural gas → generates 9.500 kcal.
- 1 kg of pellets ——– → generates 4.600 kcal.
Price of each fuel:
- Heating oil → € 0,91 / L
- Natural gas —————- → € 0,64 / m³
- pellets ———————- → € 0,26 / Kg
* These prices are estimates, are totally subject to variation according to the market, the quantity and quality of the product or seasonal offers.
Looking at these equivalence tables we can conclude that to generate 10.000 kcal the most economical are the pellets and also the least polluting. Everything else is at your discretion.
