Abstract
A dishwasher, in particular a commercial single-tank dishwasher or commercial multi-tank dishwasher, for washing washware includes a liquid transportation line () with at least one supply line for supplying liquid at a first temperature and comprising at least one discharge line for discharging liquid at a second temperature. The supply line and the discharge line run coaxially in relation to one another, so that either the supply line or the discharge line forms an internal line () which runs in the direction of extent of the liquid transportation line () within the respectively other supply line or discharge line which for its part forms an external line (), and thereby form a countercurrent heat exchanger.
