As you know, pellets are a type of fuel extracted from wood, designed to make pellet stoves generate heat, and we reported the best model of them a few weeks ago. Although very good, the pellet furnace itself cannot operate at full capacity because fuel plays an important role in heating the house. If the quality is poor, the latter will generate very little heat and generate a lot of ash, effectively preventing the furnace from operating in the best way.

It is easy to guess that a good particle will have different effects in small, medium and large environments. This is why you should only buy high-quality packaging while avoiding possible furnace failures due to humidity and relative humidity. deterioration. In this regard, we usually tend to buy the cheapest packaging, but as mentioned earlier, this may have a negative impact on the maintenance of the furnace and the actual calorific value, which is why we will focus this article on the best ones. The pellets are available on the market, and then in the second part, we discover how to identify good products from inferior products.

With ENPlus A1 certification, Salzburg pellet furnaces will be able to generate the maximum heating value of your pellet furnace, which is the best fuel for this type of equipment. In fact, this certification guarantees that the residual ash content is less than 0.7% and the calorific value is at least 4.6 kWh per kilogram. In this case, we are faced with the ability to produce 4.9 Kwh / Kg pellets and 0.3% ash residue. A product that will not disappoint you, you can even use it as a cat litter because it can absorb the smell without leaving a trace.

In this case, the particles we face come from coniferous trees, such as fir, larch or stone pine. Just like the previous solution, we are talking about certified pellets ENPlus A1, with a calorific value equal to or greater than 4.6 kWh per kilogram, and ash less than 0.7%. The manufacturer also stated that the humidity provided by the pellets is less than 10%, which is really great. The packaging is 15 kg, so it has a better quality/price ratio than the Salzburg solution.

If you are looking for high-quality pellets with a higher quality/price ratio, then Schultz will definitely suit you. In fact, the 15 kg package always sells for only 4.99 Euros. Like every article we report, it has ENPlus A1 certification, which makes it ideal for ensuring that the pellet furnace emits maximum heating value and there is almost no ash. The pellets are made from the highest quality spruce wood and come entirely from forests that are considered sustainable.

If you want to buy a large amount of pellets at once, then you should consider Timbry packs. The seller offers 10, 20, 40 and 70 bags, each weighing 15 kg. Also in this case, we are talking about high-quality pellets with ENPlus A1 certification and high calorific value. The wood for this product comes from forests in the Czech Republic, but not from any forest, but from forests that are regularly controlled and regenerated. In short, a 100% natural and well-made pellets are perfect for getting your stove to work properly.

Among the best pellets for your stove, we also point out the MHL solution, which offers EnPlus A1 certified softwood. In this case, the manufacturer’s declared calorific value is even higher than 5 kWh per kg, which means that the tray furnace will work at full capacity. Like almost all packaging of this material, this is also a 15 kg bag. If we consider the quality of the product, the price is not bad at all.

As expected in the initial stage, buying a good pellet not only means letting the furnace work at full capacity and increasing its calorific value, but it also reduces its maintenance, which is why knowing how to get from a poor one. In this regard, we at Tom's Hardware will try to show you the right path, and we expect that obtaining high-quality pellets will be a breeze, because the quality is almost entirely dependent on the certification of the latter.

As mentioned above, certification is the first and possibly only factor in determining whether a particular particle is of good quality, medium or poor quality. If you plan to buy the best, you must check whether the pellets have EnPlus A1 certification, which is the most famous in Europe and other parts of the world. Therefore, this certification will prove that you are processing high-quality pellets that can release the highest calorific value, while generating negligible ash.

There are certified EnPlus, it is divided into 3 categories; A1, A2 and B. As you understand, the highest quality can be achieved by using products declared as A1, but in many cases you can also rely on A2 solutions, first of all to save costs. On the other hand, Category B should be excluded because it is designed for non-domestic use and has a very high ash residue that may damage certain components of the pellet furnace earlier than expected. Below we introduce to you the main characteristics of the 3 types of EnPlus A1 particles:

Although this is a factor related to certification, it is best to check the manufacturer's stated humidity. In fact, if the particle is wet, its calorific value will not be the best, because part of the latter will focus on evaporating moisture, which will also have a negative effect on the combustion chamber, which will become dirty. Basically, the humidity of a good particle should not be higher than 12%, but should be lower than 8%.

You may have noticed that in the previous paragraphs, we often mentioned calorific value because this is what makes the furnace heat up the environment. If this is low, the stove will not work properly, or more precisely, it will not reach the designed performance, making the heating of the house slow or ineffective. Having said that, we can say that the calorific value is also closely related to the certification of the pellets, because the calorific value of EnPlus A1 is guaranteed to be at least 4.7 kWh/kg. However, in this regard, it must be said that a value higher than the reported value may be untrue, because manufacturers tend to measure it in an anhydrous state, considering that it is more logical to check the water content.

As you know, the pellets are not exactly the same, but are made of various types of wood. Among them, we point out firs, beech, ash, and poplar, but there are many others. Generally, the first two are the best, but it is worth pointing out that the pellet stove can also play a small role, and it may perform better with one specific wood rather than another. If we study deeply, we will find that the yield and heat of beech tend to be higher, but it will produce more ash. On the other hand, fir is the opposite, because it produces less ash and lower calorific value. Therefore, you need to find a suitable compromise, which can be found in so-called softwoods and hardwoods. The following is the most famous list:

If we compare pellets with other heating systems, at least from a purely economic point of view, this is the winner. The reason for saving is that the material is not very dense and the transportation cost is low. On average, a 15 kg package will last for a few days. According to calculations, compared with gas, the use of pellet stove can save up to 70% of the cost, up to 40% compared with diesel, and up to 20% compared with methane. In addition, if you buy pellets in the summer, you can save even more. In fact, between May and July, due to supply and demand issues, the price of pellets is often lower than in winter months.

Although the above certification is the main factor to be considered, you can use some "tricks" to understand whether the quality of the pellets you buy is high or low. An easy way is to check for sawdust. If it is present in large quantities and in the form of dust, it means that the quality of the particles is poor and it is likely to malfunction. On the other hand, if the wood is completely intact, it means that the product is very good. Another way to check the quality is to immerse a small amount of pellets in a glass of water. In this case, if the latter sinks and the water does not become turbid, you will face a good particle.

The pellets are made of various organic materials, such as wood chips, bark, sawdust and other by-products of wood grinding. Even cork, that is, wood that is not suitable for construction, can be used to make pellets. However, manufacturers often use waste wood or other by-products of the manufacturing process to produce pellets, such as corn stover, straw, and similar agricultural materials. No matter what material it is, it is ground and pressed by a hammer mill to ensure uniform size, shape and density. During this process, the temperature of the product rises. Once cooled, the humidity will drop to about 4-8% and the product will harden. The low moisture content allows longer combustion and constant heat, while minimizing particulate emissions.
