Electric water heater EL. 10 EM NADUM. (OS) BEST

Product detailed description

This electric water heater is designed for installation in residential and small commercial buildings where a compact, on-demand hot water supply is required. It is commonly used in bathrooms, kitchens, and utility rooms to provide immediate access to hot water without the need for a central heating system. The unit is typically installed on a wall near the point of use, connected to the cold water supply and electrical circuit. It is suitable for applications where space is limited and a dedicated hot water source is needed for one or two outlets.

The heater is designed for integration into standard plumbing systems and can be used in conjunction with thermostatic mixing valves or as a standalone unit. It is not intended for high-flow applications such as showers or dishwashers due to its 10L capacity and 1.5kW heating element. The manual control allows for basic operation without the need for complex programming or monitoring systems.

Technical parameters

Installation and connection

Installation requires a secure wall mount and a cold water supply connection with a 1/2 inch thread. The electrical connection must be made to a dedicated 230 V circuit with appropriate fuse protection. The unit must be installed in a dry location with adequate ventilation. The pressure rating of 0.6 MPa must be respected by ensuring the incoming water pressure does not exceed this limit. Common installation errors include incorrect electrical wiring, failure to secure the unit properly, and neglecting to check the cold water inlet for correct thread type and size.

Compatibility and accessories

This water heater is compatible with standard plumbing systems using 1/2 inch threaded connections. It may be used with thermostatic mixing valves for temperature control, though these are not included. Additional accessories such as wall mounting brackets and electrical cables may be required depending on the installation location and existing infrastructure. No related products are available for this model.

Technical background for designers

The unit operates by heating water stored in an insulated tank using a 1.5kW electric heating element. The tank is insulated with expanded polystyrene to reduce heat loss and maintain water temperature. The tank is protected against corrosion by a ceramic enamel lining and a magnesium anode. The manual control allows for basic operation without the need for complex automation. The unit is designed for integration into standard domestic water systems and requires no additional control systems for basic operation. The service life and efficiency are affected by water quality, frequency of use, and the condition of the anode and insulation.

Service and operation

Regular inspection of the magnesium anode is recommended to ensure continued corrosion protection. The electrical connections should be checked for signs of wear or overheating. The tank should be drained periodically to remove sediment buildup. No specific service intervals are provided in the technical data.

Frequently asked questions

Can this water heater be used for a kitchen sink and a bathroom sink simultaneously?
It depends on the flow rate and usage pattern. The 10L capacity and 1.5kW heating element may not be sufficient for simultaneous use of two outlets at high flow rates.

Is a thermostatic mixing valve required for this unit?
A thermostatic mixing valve is not required for basic operation but may be added for temperature control and safety in some applications.

Can this heater be installed in a utility room with a floor-standing configuration?
It is designed for wall mounting and should not be installed in a floor-standing position as this may affect stability and performance.

Can this unit be connected to a solar water heating system?
It is not designed for integration with solar water heating systems and should not be used in such configurations.
