The appliance has a combustion chamber and two or moreheat exchangers arranged above one another, the heat exchanger lying at the bottom in the appliance being assigned to a condensation chamber. In order to be able to act upon this heat exchanger independently of the water and on the whole to raise the degree of efficiency of the appliance, the heat exchanger of the condensation chamber is assigned a fresh air inlet and a fresh air outlet, air thus being guided through the heat exchanger, which air is, after heating, supplied to the burner of the appliance. <IMAGE> |
