    PRODUCT DESCRIPTION

    HAKL 3K DL will be appreciated by all customers who require instant and unlimited heating of large amounts of hot water without the need for accumulation (storage tank) water heating. The heater does not overload the electrical grid, as the output is distributed across a three-phase electrical connection. Comfortable use of the heater is achieved by a microprocessor, which maintains a constant temperature of the heated outlet water even as the flow rate changes.
    The automatic smooth increase or decrease of the heating element output applies not only when using a sink or shower tap, but also in winter and summer mode. This automatic power adjustment makes the heater both powerful and economical at the same time. The backlit touch display, which measures total electricity consumption and litres of water, only underlines the technical sophistication of this instant water heater.

     

     

    Long Life Technology

    The patented dry heating Dry Heating system in HAKL 3K-DL instant water heaters minimizes limescale build-up and thus the burning out of the heating element. Reliable water heating is ensured by a heating element housed in a protective sleeve, which is not in direct contact with the water. This heating block, manufactured using Long Life Technology, is characterized by a long service life even with excessive consumption of heated water.

    SUITABILITY TABLE

    To make choosing the right instant water heater model easier, the manufacturer has prepared a clear suitability table. It is sorted by output and type of use - i.e. how demanding the water consumption is.
    Despite their higher output, electric instant water heaters achieve high financial savings, since they have no built-in tank. Unlike storage water heaters, they heat an unlimited amount of water. They heat the water continuously, which means that as the flow rate increases, the temperature of the heated water decreases.
    When choosing an instant water heater, the intended use must be taken into account. For example, showering requires heating up to three times as much water as washing hands, so it is necessary to select the correct output of the instant water heater.
     

    Note:   
    The values in the table are indicative; five symbols ••••• indicate maximum suitability of use, the symbol x indicates unsuitability of the product.
    You can easily select water heater models by output in the main category using the filtering tool. 

     

    Note:
    The PARAMETER values were measured at:
    - mains voltage 228 − 230 V 
    - dynamic water pressure 0.3 MPa (3 bar) 
    - inlet water temperature 12°C
