A heat exchanger (1) has a heat-exchanger unit comprising one or more substantially coaxial coiled tubes (21-23) and a casing (2) for housing the heat- exchanger unit. The casing (2) has a first end wall (3), a second end wall (4), and a peripheral part (5) between the two end walls (3, 4). Each tube (21-23) has a first end (21a-23a) and a second end (21b-23b). The heat-exchanger unit is supported by the first end wall (3) of the casing (2), with the first end (21a-23a) and the second end (21b-23b) of each tube (21-23) that is located substantially at the first end wall (3) of the casing (2). |
