Ariterm Bionet+12 combines a compact pellet boiler with Ariterm BeQuem pellet burner to a functional and effective unit. Easy use, environmental and efficiency is the best and fulfils the demands for easy handling and effective pellet combustion. Ariterm Bionet has a vertical convection system, which reduces the soot so that the boiler can retain high efficiency between service intervals. The service need is dependant on the pellet quality and outgoing effect (fuel consumption) and can vary seasonally. The large ash box of 20 litres is easy to remove and empty.
