Biomass boilers are very efficient as they have been built using the best of modern technology. They will currently operate at 90% efficiency which is a huge amount more than with conventional boilers. How efficient your system will actually be will also depend on how energy efficient and may also depend on the air flow around the boiler and the type of flue fitted.

Generally, biomass boilers will work best when they are fuelled with logs and wood pellets. Heat and fuel are never wasted and they produce very little ash and smoke. Any ash that is produced can simply be used in your garden as fertilizer. When the logs are burnt, the CO2 that is released into the atmosphere is exactly the same as is produced when a plant dies naturally and is left to rot. Even if you take into account the emissions of fossil carbon dioxide produced in planting, harvesting and transporting your fuel, by replacing a fossil fuel source with wood you will be cutting CO2 emissions by an average of 90%.

To make sure your boiler keeps running at this high efficiency level, it must be kept in good working order. Fortunately, biomass boilers require very little in the way of maintenance and this can usually be carried out without expert help. However, to get the very best from your boiler to begin with, you should make sure you get a long standing company with a good reputation to fit it. They should be able to answer all of your questions and be able to advise on the best type of system for your household’s needs.
