PRODUCT DESCRIPTION

HAKL 3F-V will be appreciated by all customers who require immediate and unlimited heating of hot water in large quantities without the need for an accumulator (tank) water heater. The heater does not overload the electrical grid, as the power is distributed by connecting to a three-phase electrical supply. The comfortable use of the heater is achieved by a microprocessor that maintains a constant temperature of the heated water output even with varying flow rates.
Automatic smooth increase or decrease of the heating element power is used not only when using a kitchen sink and shower battery, but also in winter and summer modes. This automatic change in heating power makes the heater both powerful and energy-efficient. The backlit touch display with measurement of total electricity consumption and water volume only underline the technical advancement of this water flow heater.

Long Life Technology

The patented dry heating Dry Heating in the HAKL 3F-V flow water heaters minimizes limescale buildup and thus also burning out the heating elements. Reliable water heating is ensured by a heating body housed in a protective casing, which is not in direct contact with the water. This manufactured heating block Long Life Technology is characterized by a long service life even with excessive hot water consumption.
