Electrolux IH 18, IH24, IH21 manual Hot water flowrate, Care and maintenance of the appliance

Hot water flowrate

Up to the appliance’s max. power limit, the instantaneous water heater supplies the set hot water temperature regardless of the water flowrate selected.

If the hot water temperature is not attained when the hot water valve is fully opened, more water flows than can be heated by the appliance power. In this case, the hot water tap must be slightly closed.

Because of the different inlet temperatures, the hot water output varies depending on the season.

The following outlet flowrates for bath or shower water (40°C) or washbasin/ sink water (55°C) are attained at the inlet temperatures of 6°C, 10°C,

and 14°C.

Care and maintenance of the appliance

Clean the plastic housing as necessary with a damp cloth and dilute soap solution. Never use any abrasive, scouring, and solvent-containing detergents. The instantaneous water heater generally needs no maintenance. Regular inspection of the appliance by a trained engineer will ensure its operational reliability and prolong its service life.

Scale deposits in the outlet of fittings reduce the water flowrate. The air bubblers of the fittings or hand shower head must therefore be cleaned from time to time.
