The heating device has a blower (7), a heating burner (1), and a heat exchanger (2) for cooling the exhaust gases of the heating burner. The cooled exhaust gas is removed through an exhaust conduit (4), and combustion air is supplied to a fresh air conduit (5). A water pipe and a domestic water storage tank (6) are conductively connected with a recupereator (3) arranged downstream of the heat exchanger. The fresh air conduits (5,11) provided at a low pressure chamber (10) are connected to an exit opening for passing air to external environment. |
