Boiler of the so-called combined heat accumulation type.

摘要

A so-called combined heat accumulation type boiler comprises a first gas-water heat exchanger (4), for producing hot water for space heating, circulating in a primary piping circuit (5) between inlet openings (6) and outlet openings (7) of the boiler, a heat accumulator (18) in heat exchange with a second water-water heat exchanger (8) for producing sanitary hot water from which it is structurally independent and valve means (11, 36) for selectively diverting the hot water for space heating toward the water-water heat exchanger (8) or the outlet opening (7) of the boiler. <IMAGE>
