Abstract
In tunnel-type washing machines (10) for commercial laundries, the main-wash liquid is heated by steam in particular. This means a steam-generating system is required in the laundry. The invention makes provision for the main-wash liquid to be heated up by means of a flow heater, preferably a heating device (26) which has a gas burner (28). As a result, the tunnel-type washing machine (10) can also be used in laundries which do not have a steam generating system. The invention also makes provision for the gas burner (28) of the flow heater to be operated continuously since treatment liquid which is required for other purposes, preferably treatment liquid which is temporarily stored in a storage tank (31), is heated up after the main-wash liquid is heated up. Uninterrupted, economical operation of the gas burner (28) is ensured as a result.
