Abstract

A heat exchanger (1) for domestic boilers comprises: - a metal tube (2) through which the water to be heated flows; - fins (4) associated with the outside of the tube (2) and designed to come into contact with the combustion products of the boiler. The metal tube (2) and the fins (4) are made as separate parts, of aluminium alloy and are interconnected.
