A cast iron or aluminum sectional boiler has essentially annular sections, one front section, one rear section and at least one center section being provided which form a furnace chamber having essentially surrounding heating gas passages, and their annular water compartments are connected to one another via hubs. The sections have one return connection piece and one feed connection piece, one flue spigot as well as at least two anchor rods for holding the section block together. Annular gaps are provided as heating gas passages between each two adjacent sections, and that the heating gas passages are subdivided into a primary section and a secondary section.

Cast iron or aluminum sectional boiler

A method for regulating a temperature of a combustion medium in a mixing zone of a burner and a method for regulating a burner, in particular an oil burner, a burner performance being modulated. A heating system including a burner, which includes a regulating device, and a regulating device for a burner, in particular an oil burner. The method/system is intended to provide as constant a temperature as possible in the mixing zone during the different operating modes and with changed burner performance. The combustion air flows through a first supply tract in a first operating mode and in adjustable proportions through the first and/or a second supply tract in a second operating mode, and the combustion air is supplied with heat via a heating element, which may be switched on and off, in the first supply tract, and with heat from a combustion zone in the second supply tract.
