We have grown tired of the high prices of electricity and we are in full search for alternative energy sources to activate the heating at home this year. One of these options is the pellet stove, which we have been told has great energy efficiency and, above all, low cost. However, we do not know which one to choose to heat our house without making the mistake of spending more power than we need or, on the contrary, falling short. Let’s see if we can resolve those doubts with the following tips.
Adjust the power to the needs of your home
A mistake that we usually make is installing a type of stove that works at a higher power than we need. By doing this, we are not only creating a more charged environment, but we are increasing the consumption of energy, in this case biomass. The opposite is also the case, buying a stove that gives less power than we need, so we will spend more to reach the temperature we are looking for.
So that this does not happen, it is essential to know the power time that our pellet stove needs. If we are talking about a stove for domestic use, the power range does not exceed 70 kW, while those with medium and high power must exceed 70 kW, but these are those intended for industry, sports centers, hospitals, etc. And it is not the case.
Types of pellet stoves according to their power
As we said, the adequate power will save us unnecessary spending and improve the comfort of the room. That is why it is important when buying a pellet stove to know our home, its dimensions and the use we want to make of this type of heating, if it is going to be for a stove or for a boiler.
If we take into account that domestic pellet stoves are included in a range that goes from 4 kW, 8 kW, 12 kW to 16 kW and so on. The next step is to know what each kW covers. In this case, each kW has the capacity to air-condition a room of about 10 m2. Therefore, if our house measures 120 m2, we will need a stove with a power of 12 kW.
On Amazon you can find a wide variety of models:
Bilake 6 kW pellet stove
- 6 kW power.
- Smoke outlet.
- Three colors.
Isola 9 kW pellet stove
- 9 kW power.
- Remote control and WiFi connection.
- Temperature control probe.
Slim 22 kW pellet stove
- 22 kW power
- Daily, weekly or weekend programming.
- adjustable temperature
Energy efficiency
Now, that’s not all. When it comes to maintaining a correct temperature and a reduced energy cost, it is not enough to have a good stove, it is also necessary to calculate the energy efficiency. This happens to avoid the loss of energy and thus reduce the time that our heating (stove) is working. To achieve good energy performance, the fundamental step is to have good insulation.
This insulation is achieved when doors and windows are perfectly sealed and have a correct thermal material (it is best to install PVC or aluminum windows). It is also necessary to prevent air leaks through blinds or cracks, sealing these passages with materials such as polyurethane. If we take all these factors into account, we can achieve the perfect balance between energy efficiency and power. According to estimated calculations, under these conditions the performance of a pellet stove can be between 70 and 85%.
