In Europe, there are already more than two million biomass boilers for domestic use with power less than 50kW, and annual sales of over 200.000 units. By country, the market is led by Germany with a park that exceeded 2020 operating boilers in 320.000 and annual sales of more than 40.000 units. Spain with updated data had 60.000 pellet boilers for domestic use installed in 2021, the year in which 8.800 units were sold.

Respecto a the installation of pellet stoves, the latest statistical data estimates that there are already 7 million pellet stoves operating throughout Europe with annual sales of over 800.000 units. The positive evolution of sales in the countries of the Mediterranean area stands out. Italy has just over 2,1 million stoves in operation in 2020 and France with 1,2 million pellet stoves in operation. In 2021, Spain had 430.000 operational pellet stoves and annual sales of over 66.000 units.

 
Alessandro Stevan, Export Manager of La Nórdica-Extraflame La Nordica - Extraflame presents its new range of pellet stoves and boilers at Expobiomasa 2021 in this video More information:
Boilers and stoves up to 50kW incorporate more sophisticated technology. The new European Ecodesign regulations require great emission control and high efficiency. The leading manufacturers present at the fair achieve attractive design equipment, comfort, automation and significant savings for the user.
In addition to the Innovation Award given to Sugimat, ÖkoFEN's ZeroFlame technology and Palazzetti's total pellet combustion system will receive second prize. In this call, and for the first time, the Innovation Award in the field of renewable gases is awarded.
Brand founded in 2018 with more than thirty years of experience in the biomass heating sector, Nobis is presented for the first time in the Spanish market with a range of products equipped with the most advanced technologies available on the market. Specialized in pellet stoves and fireplaces, Nobis offers a complete range of products, suitable to satisfy customer needs: Quiet, versatile, ecological, autonomous, remote controlled stoves, with modern and innovative finishes and coatings. .
With a minimal designimalWith a view and highly efficient operation, the Murcian firm brings to the Valladolid Fair a new design for its outdoor stove par excellence: the Armonía II model. With an innovative natural ventilation mechanism, the design and specifications of this outdoor stove have been simplified to the maximum in order to eliminate any problem, preserving a striking and elegant aesthetic.
The new Iris model in its Hydro version will be an attractive solution for heating homes by using water.
It is a new concept of comfort and equipment in biomass heating. This new range includes as standard all the necessary equipment to produce heating and domestic hot water at home in a reduced space, and also without the need to change the existing installation. The possibility of controlling the boiler from anywhere, through a mobile device, is also incorporated as standard. 
In Spain and Portugal, despite being a very widespread method, we should avoid cladding with a combination of plasterboard and rock wool to cover chimneys, because using plates with vermiculite has many advantages for users and consumers. According to Justo Fernández, manager of Suakontrol, and an expert in thermal insulation, in northern Europe they throw their hands up when they are told about the coating that we generally use here. Why not use plasterboard and rock wool in a cladding?
Rika's Domo Back model complements Rika's best-selling model with a kitchen oven. With adjustable temperature from the touch screen, both for the stove and for the oven, independently, the Domo Back model takes a step forward in the management of the energy generated with a view to making the most of it. In addition, this model can incorporate up to two convection air fans.
It is a disruptive concept in air conditioning that allows heating and renewing the air in the whole house simultaneously, unifying heating and ventilation starting from a simple biomass stove. Instead of heating the stale air we have inside, it directly heats the fresh air, generating "replacement heat".
This revolutionary technology allows the burning of all unburned waste from pellet combustion equipment, many of which fall into the brazier. At the end of the combustion process there are usually tiny mineral particles that no longer burn
This system was tested in the TÜV laboratories. In a cyclical test simulating the various operating conditions throughout a year, an average particulate emissions of just 2 mg / m3 (13% O2) were measured. This level of practically negligible emissions is achieved with a new design of the flame tube in the combustion chamber, and a divided recirculation of the exhaust gases. These gases feed the primary air in the lower zone and are injected into the upper burning zone at high temperature.
