Abstract (en)

A hybrid boiler comprises a fired pipe heat exchanger encased in an internal jacket (9), a pipe coil (7) encased in an external jacket (1) which on the one side is closed with a lid (12) incorporating a burner plate, and on the opposite side is closed with a condensate tray (4), water inlet (3) and outlet (11) stub pipes and flue gas exhaust stub pipe (5). Between the external jacket (1) and the internal jacket (9) there is a longitudinal partition (8) separating the internal space between the said jackets (1, 9) into two chambers which are connected to each other below the lid (12), and the chamber formed between the longitudinal partition (8) and the internal jacket (9) is connected to the chamber inside the internal jacket (9) above the condensate tray, where placed in the chamber between the external jacket (1) and the longitudinal partition (8) is a pipe coil (7) fitted with a cooling agent inlet stub pipe (10) and cooling agent outlet stub pipe (2), and the water inlet stub pipe (3) is connected to the said chamber formed between the external jacket (1) and the longitudinal partition (8), whereas the water outlet stub pipe (11) is connected to the chamber formed within the internal jacket (9).
