摘要： An apparatus for heating water, especially a hot-water boiler. The apparatus has a combustion chamber and two or more heat exchangers that are disposed one above the other. The heat exchanger disposed in the bottom of the apparatus is associated with a condensation chamber. In order to be able to operate this heat exchanger without water, and to be able to raise the efficiency of the apparatus as a whole, the heat exchanger of the condensation chamber is provided with a fresh air inlet and a fresh air outlet. Air is conveyed through this heat exchanger, whereupon it is heated up. This warmed air is supplied to the burner of the apparatus.

摘要： A device for evacuating into the ambient air combustion products from a condensation boiler, in which at least one downstream section of the conduit for evacuating the combustion products is coaxial to the conduit for admission of the combustion air necessary for the burner. Means are provided for returning to the outside a fraction of the air collected in said admission conduit. The downstream section of the conduit for evacuating the combustion products, the coaxial section of the admission conduit and the means for returning to the outside a fraction of the collected air define a first heat exchanger. Means also are provided for diluting the combustion product with the fraction of collected air, the dilution means being located in the vicinity of the opening for suction of the combustion air and for rejection of the combustion products into the ambient air. A second heat exchanger is provided between the first heat exchanger and the boiler, whereby the combustion products issuing from the boiler further heat the combustion air heated in the first heat exchanger. The second heat exchanger is of the trickling water type to increase the humidity of the combustion air. The invention is particularly applicable to boilers with vents.
