Abstract

A container (2) adapted to avoid peak temperatures of water delivered from a heat exchanger (1) is provided with interior reinforcing means (9-11, FIG. 1; 13-13′″, FIGS. 5-18) connecting opposite parts of the wall (2′) of the container (2). Even with a thin container wall this makes it possible to use a box shaped container design without risk of deformations due to variations in the water pressure. The reinforcing means may consist of stacked interconnected plates (13-13′″)—e.g. having the same form and size as plates (12-12″) used in a plate heat exchanger connected to the container (2).
