ABSTRACT:
A system and method for controlling soot removal in a heating device (2) in which heat energy is generated by combustion of a fuel, with accompanying production of soot, to produce combustion product gases, and heat energy is transferred from the product gases to a heated medium via a heat exchange surface on which the soot collects in a layer, by: producing (10) an indication of the present thickness of the soot layer; determining (12) the increase in cost of transferring heat energy to the heated medium due to the soot layer; and performing (4) a soot removal operation starting at a time selected on the basis of the determined cost increase.
