What central heating boiler for wood chips, sawdust and pellets?

The new direction of the European Union is the green deal, i.e. the transition to renewable energy and increasing the energy self-sufficiency of individual countries. The departure from gas or coal is visible and many hotels, schools, public buildings, multi-family and single-family houses are still heated with gas or fossil fuels. There are energy carriers that, like electricity, will probably become more expensive in the future, which will significantly increase the cost of heating in winter. That is why many companies, business entities, farmers, and production plants are already looking for alternative sources of cheap heat and electricity.

What is an alternative source of energy to gas and coal?

Central heating boilers for renewable fuels are certainly a cheap alternative source of energy to gas and coal. Widely available renewable fuels include: wood, wood chips, pellets, briquettes, straw, husks, grains, pomace or production waste such as sawdust. Generally, these are free or cheap fuels derived from wood and its processing and from agricultural production, i.e. agro.

Are pellet central heating boilers popular and worth recommending?

Pellet central heating boilers are very popular because sawdust granulate is widely available in many construction stores and is characterized by an attractive price. Sawdust pellets are more expensive and granulate from agrobiomass or sunflower husks is cheaper and equally ecological. Unfortunately, it requires specialist boilers and burners for combustion, we especially recommend the Biowarmer series. Pellets are an alternative fuel to coal or gas because it is a fully renewable fuel and produced by thousands of small local producers. The limitation of pellet use is the fact that the production of pellets is quite expensive, energy-intensive and requires a large amount of raw material, i.e. sawdust, which is not always available. We therefore have a significant limitation in the possibility of pellet production on an unlimited scale. Adding the costs of depreciation of machines and energy carriers makes pellets one of the more expensive renewable energy resources on the market.

What is an alternative to a pellet boiler for heating a company?

So what is an alternative to a pellet boiler to heat a company economically? We have a number of unprocessed fuels that are much cheaper and easier to obtain. An excellent alternative to pellets is the post-production waste from which it is made! Sawdust and wood chips, which are a by-product of wood production, are used to produce pellets. And what if we told you whether they can be burned without the need to be processed into granulate? Why invest in production lines, machines and dryers and incur the costs of pellet production when you can burn sawdust and wood chips efficiently and ecologically? The Biowarmer series of boilers is ideal for this and burns basic energy raw materials such as sawdust, dust, wood chips and edgings in a low-emission way. This is an ideal proposition for the carpentry and furniture industry because we have free heat energy. In order to professionally select a biomass heating boiler for a given heating surface or building volume, many factors are needed, which our engineers analyze:

• Degree of building insulation

• Living temperatures during the company's operation

• Heating power of heat receivers/distributors, i.e. usually what is the heating power of radiators, underfloor heating or air heaters

• Type of heating system and its operating curves

• Type of fuel, its calorific value and fraction as well as humidity

• How we want to load the fuel, parameters of the boiler room and biomass storage

• Service access to the boiler room

• Possibilities of servicing biomass boilers, including service spaces and access to individual elements of the automatic biomass heating system

What is an alternative to a pellet boiler for heating a house?

The Biowarmer series of heating boilers with a biomass feeder can also be used in home conditions for cheap heating at home. We have a series of Biowarmer home boilers for heating every house with wood chips, sawdust, briquettes. It should be remembered that these fuels are much cheaper than pellets and provide greater energy independence for the user. They are therefore an excellent alternative to pellets and, importantly, the comfort of use and combustion parameters are similar to pellets. Heating boilers with a Biowarmer feeder are fully automatic, they ignite and extinguish automatically. They have advanced automation of the heating system control also via a WIFI module and a fully automated combustion process, so they are 100% comparable to popular pellet boilers. They only have a larger fuel tank because crushed biomass is spatial and has a different bulk value coefficient. It is loose, not compressed, so it takes up more space and requires much larger fuel tanks. For example, if we want to burn 1 ton of pellets, we need a sawdust or wood chips tank almost 2-3 times larger to provide a similar amount of fuel with a similar calorific value

What central heating boiler for wood chips, sawdust and pellets?

So what central heating boiler should you choose for wood chips, sawdust and pellets to heat your home or business cheaply? Cheap pellet heating boilers only allow you to burn sawdust granulate and nothing more. If you also want to burn other cheaper fuels such as sawdust, wood chips, sawdust briquettes or straw, you need to invest in a much more advanced heating system. Biowarmer biomass heating boilers have a number of innovative automation systems, thanks to which it is possible to burn many types of biomass in them regardless of its calibration, humidity and fraction. We can effectively burn biomass up to 40% humidity and fractions up to 10 cm. We can say that these are heating devices for burning crushed biomass of any fraction and humidity.

Is biomass gasification technology good?

Biomass is a widely available fuel and can be effectively burned in various ways. Biomass gasification technology, or pyrolysis, is one of the most advanced. Combustion in this technology is two-stage and very ecological because we ultimately burn gas created from biomass, which is an excellent alternative to natural gas. Such biogas is cheaper to obtain and uses the potential of renewable energy, which is widely available practically everywhere. The exploitation of oil and gas deposits, which make Europe dependent on Eastern and Arab markets, is currently unwelcome by the European Union. It is therefore not surprising that the green deal is directed towards renewable energy from biomass, which allows for costfree heating of homes or companies, similarly to photovoltaic systems that generate free energy from the sun or wind farms that provide free energy from the wind. Free energy from renewable resources such as biomass, energy from the sun or from wind or biogas are currently the main resources of Europe, which should be used 100% to become independent from gas or oil supplies from Russia or Arab countries. This ensures not only full energy independence but also full use of Europe's own resources to produce free heat and electricity.
