Biomass boilers do require some maintenance. Many manufacturers recommend servicing twice a year, although this is often included in the installation cost. Many systems have automatic fuel loading that removes the need to manually load fuel. You will need to remove the ash from the boiler, but this is as easy as emptying a vacuum cleaner.
