An instantaneous heat exchanger for heating sanitary water in a combined boiler has a casing defining a chamber for a first fluid, within which there extends a conduit or tubing for a second fluid. At least one of the chamber and the conduit has a substantial capacity of containment of the respective fluid, preferably between three and six litres, and the heat exchanger is pre-arranged for hydraulic connection to a standardized connection assembly for an ordinary plate-type heat exchanger for a combined boiler. |
