electric instant water heater with adjustable output, electronic switching and pressurised operation 21 kW

Product detailed description

The HAKL 3K DL 21 electric instant water heater is characterised by immediate and unlimited heating of hot water in large quantities without the need for storage (tank) water heating. The heater does not overload the electrical grid, as the output is distributed via connection to a three-phase electrical supply. Comfortable use of the heater is achieved by a microprocessor that maintains a constant temperature of the outgoing heated water even as the flow rate changes. The automatic smooth increase or decrease of the heating coils' power output applies not only when using the sink and shower mixer, but also in winter and summer mode. This automatic change in heating output makes the heater a powerful and economical model 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.

The patented Dry Heating system in these instant water heaters minimises limescale build-up and thus also burn-out of the heating coil. Reliable water heating is ensured by a heating element housed in a protective sleeve that is not in direct contact with the water. This Long Life Technology heating block is characterised by a long service life even with excessive draw-off of heated water.

USE: washbasin, sink, shower, bathtub.

CHARACTERISTICS:
• installation into a domestic water system at 0.6 MPa (constant pressure)
• connection to 3 x 230V voltage, triple heating output
• immediate and continuous water heating from a minimum switching pressure of 0.12 MPa (depending on heater output)
• dry heating coil with patented water heating
• automatic smooth increase of heating coil output, e.g. from 5 to 15kW (depending on heater output)
• microprocessor-controlled constant temperature of heated water as flow rate changes
• outlet water temperature setting in the range of 30°C to 60°C
• total measurement of electricity consumption and litres of water
• backlit touch display
• button for switching off heating (standby mode)
• each heating coil with its own resettable thermal fuse
• thermal sensor at the water inlet and outlet
• water flow switch and adjustable pressure safety valve

SPECIFICATION:
Pressurised operation: the heater can be installed directly into the water system for one or more commonly available mixer taps.
Electronic switching: water heating is switched by electronic control that uses protective sensors and thermal fuses.
Automatic output switching: automatic smooth increase of heating coil output, for example from 5 to 15 kW.
Water resistance IP 24: the heater can be installed above or below the washbasin.
Touch display: backlit touch display with the option to set the outlet water temperature in the range of 30°C to 60°C.
Dry heating coil: the dry heating coil with patented water heating minimises limescale build-up.
Voltage 3 x 230 V: connection to a three-phase electrical grid. The heater is installed on all three phases of the three-phase electrical supply.
Mounting bracket: easy wall mounting is enabled by the mounting bracket and screws included in the package.
Metal flange: the massive design of the metal flange increases the heater's durability during installation.
