What does a biomass boiler burn?

It works with agricultural waste: corn, wheat, and olive stones. But also wood. The most basic version starts at €4.

How does a biomass boiler work?
In theory, the operation is very similar to that of a gas boiler. In practice, everything changes as the combustion of biomass involves substances and waste materials of origin animal, organic, vegetable. But how does it work? biomass boiler and how it presents itself as an excellent alternative to boilers that use fossil fuels.

BIOMASS BOILER

In times of high bills and prices of gas and skyrocketing energy prices, a biomass boiler is no longer an alternative to consider for homes in mountainous or rural areas, or in urban centers where methane gas doesn't reach. Rather, it's the solution to begin replacing the gas addiction and fossil fuels for both save and do not waste, that to improve the environmental impact.
But what exactly is a biomass boiler and how does it work?
First of all, a boiler of this type is characterised by a combustion chamber in which it is burned material of organic origin both animal and vegetable. These residues are also known as biomass, i.e. compounds recovered from agricultural or industrial production waste.
In particular, the products obtained can be wooden logs, pellet, hazelnuts e dried fruit scraps or sawdust for example. All materials that can be used in a biomass boiler.

HOW A BIOMASS BOILER WORKS

A biomass system works in much the same way as a gas boiler. Specifically, the organic fuel replaces the gas and dissipates heat through combustion, transferring it to the water.
The pipes, through a flow and return mechanism, let the water pass through all the heaters e radiators of a building, heating the desired rooms.
The boiler can be operated for a whole year and is designed to last. During the warmer months, however, it can be turned off completely. When installing a biomass boiler, it is advisable to apply a carbon monoxide detector. In fact, the system may not be able to burn all the contents inside it, which could cause dangerous gases which it is good to be careful of.

ADVANTAGES OF BIOMASS BOILERS

I main advantages related to the installation of a biomass boiler are:
  • Energy saving
  • Low installation costs
  • Bonuses and tax deductions
  • Cheap fuel
  • Reduction of greenhouse gas emissions

Depending on the context, for example if you are in city or Mountains and depending on the origin of the biomass, the cost of the raw material for combustion can reach zero. It should also be considered that in general the the costs of pellets or wood chips are already lower than those of gas or methane. Therefore, from this point of view, the advantage is assured.

Savings also come from another determining factor: the reduction of energy wasteThis happens both for the capacity of ggenerate more heat and for more time compared to a normal gas boiler. But also for biomasses which can prolong thebattery life of over 24 hours fully loaded.

Generally speaking, it is estimated that the saving in a year may swing between 40 and 65 percent.

BIOMASS BOILER DISADVANTAGES

Biomass systems have several advantages. But there are also some disadvantages to consider, which can sometimes make installation complex. A biomass boiler, first and foremost, is cumbersomeIts size is significant and if you don't have enough space, it will be difficult, if not impossible, to opt for this solution.

Another point to take into account is the technical room, a dedicated outdoor space of the property where the system will be placed and a independent chimney for flue gas exhaust. Compared to a condensing gas boiler, biomasses must be loaded inside the system, which can have several negative aspects. On the one hand, the inconvenience of having to empty the bags of pellets or wood chips, even quite heavy ones, inside. On the other, being equipped with astorage area of biomass.

As you might expect, biomass boilers are well suited for suburban areas, the countryside, or the mountains. However, they have been available for some time now. more compact and versatile systems able to satisfy even the needs of those who live in an apartment.

BIOMASS BOILER FOR APARTMENTS

How does a biomass boiler for an apartment work? It works in the same way as any other boiler of the same type, but it responds to some specific characteristics able to occupy one limited space e meet domestic energy needs, even in the city.
The apartment systems are also designed for to produce electric energy beyond that thermal. Therefore, considering installing one is certainly a valid alternative also from a renewable energy perspective and saving on utility costs.

BIOMASS BOILER COSTS

One of the features to consider before choosing a biomass boiler concerns your home. It is necessary to have access to a boiler, even if it is small. storage space where to best store and dry the wood logs or the type of biomass you will be using.
This is a fundamental factor since the better performance it is given precisely by degree of drying achieved by biomass. Once the suitability for installation has been assessed, we can move on to considering prices, which are far from easy to clarify.
The main reason why it is difficult to give a precise cost of a biomass boiler depends on the estimates which must evaluate several key aspects. In particular, when choosing a boiler, it will be necessary to consider:
  • i square meters to be heated in a building,
  • type of biomass: wood chips, sawdust, pellets, etc.
  • plant capacity
  • versatile o a single type of biomass
  • available space

However, it is possible to estimate how much you could end up spending with or without adding a boiler. A simple biomass boiler has a cost of around 4.000 € with the possibility of even exceeding the 10.000 euros with the addition of a boiler.

BIOMASS BOILER MODELS

After discovering what a biomass boiler is and how it works, it's time to explore some of the models you can choose from. Here are some Italian companies that offer quality products:
  • Versatile boiler (wood and pellets) – D'Alessandro CLP 30: thermal power 34.9 kW
  • Pellet boiler - Klover Ecompact 250: thermal power 23.4 kW
  • CS Thermos Lyra 27 boiler: thermal power 27 kW

Furthermore, by choosing the right boilers, you can also access theeco-bonus e advantageous tax deductions.

BIOMASS BOILER BONUS

In recent years some new measures have been introduced national plans to facilitate the domestic energy transition. In particular, access was made possible to tax deductions that leave from 50 percent to improve the energy efficiency of buildings across the country.
These are not bonuses valid exclusively for biomass plants, but tax deductions and incentives aimed at promote the replacement of obsolete, polluting boilers that still waste too much energy.
The bands of the boiler bonus biomass They include:
  • Thermal Account 2.0 up to 65 percent
  • Ecobonus Deductions for 50 percent up to a maximum of 30.000 euros
  • House bonus: deductions for renovation up to 50 percent
  • Super bonus 110 calculated on the percentage of the total amount by an expert

Lo discount on invoice and credit transfer are available only in the last three cases, while it is not foreseen for the thermal account.

To qualify for tax incentives, an inspector must inspect your home to determine the best type of boiler for your home. Then, depending on the work done and the energy efficiency improvements made to the building, you may be eligible for certain deductions from those listed.

BIOMASS BOILER MAINTENANCE

It is recommended to clean the boiler at least once a month and remove all ash residues or organic material. The recovered pile can also be used to create compost, Then natural fertilizer.
