The wall-hung electric boiler eloBLOCK is the perfect solution when there is a need for fast and efficient heat production.
Thanks to the many power modes in the compactly built eloBLOCK and its light weight, it can be used in a wide variety of ways
everywhere. eloBLOCK is your perfect partner for a heat pump system. eloBLOCK can be used as a tip boiler that cuts the last ones
large peaks in heating demand. Fits all needs eloBLOCK is available in 4 different sizes from 9 to 28 kW. In case of larger
needs, several eloBLOCKs can be combined in a cascade system. The heating elements in eloBLOCK are intelligently controlled so that
the operating hours will be similar and completely dependent on the need. Together with the regulation, the boiler is continuously controlled so that
optimal service life is achieved. To avoid unnecessary stops, eloBLOCK is equipped with a function that starts the circulation pump once a day even if there is no need.
Optimum effect for good heat eloBLOCK optimizes the flow in the heating system by controlling the internal circulation pump so that the heat delivery is optimal.
When the heat demand disappears, the boiler will be switched off, but the pump will continue so that the residual heat is carried out into the facility.
Soft start after power failure. After a power failure, eloBLOCK starts itself but the connection
of the power stages is delayed so that the network is not loaded with full power immediately.
Digital information and analysis system. The digital information and analysis system is used as
aids for correct setting so that eloBLOCK can optimize operation and thus keep energy costs to a minimum.
Operating hours are shown for heating and hot water separately, this gives the user an opportunity to optimize the efficiency themselves.
Temperature settings
The control equipment enables limitations of the output temperature for the heat between 25-85° C and 35-70° C for
the hot water. It is also possible to limit the output of the electric boiler so that it matches the fuses in the house
