Abstract (en)
A Heat exchanger element comprises a combustion chamber for the generation of hot gas; a meandering water flow channel for the flow of water to be heated; and two metal walls delimiting the water flow channel, for exchanging heat between the hot gas and water flowing through the water flow channel. The water flow channel is provided for water flow in counter direction to the flow of hot gas. The water flow channel comprises a number of consecutive parallel straight segments. The water flow channel comprises at least three U-turns which are each connecting two consecutive straight segments separated by an intermediate wall. At least one of the intermediate walls has one or a plurality of through openings.
