Electric water heater EL. 5 EM SUBS. (US) BEST

Product detailed description

This electric water heater is suitable for installation in compact spaces such as bathrooms, kitchens, and utility rooms where a small-capacity hot water supply is required. It is ideal for single-point applications such as hand basins, small sinks, or under-sink installations. The unit is designed for use in residential and light commercial buildings where space is limited but a reliable supply of hot water is essential. The manual control allows for straightforward operation without the need for complex automation, making it suitable for systems with simple hot water demand patterns.

Typical installation scenarios include retrofitting existing plumbing systems, new build installations in compact properties, or as an auxiliary heater in larger systems. The unit is compatible with standard domestic water supply systems and can be integrated into both cold-to-hot water lines and recirculation systems, provided the system pressure and flow are within the specified limits. The compact size and low weight make it easy to mount on walls or in cabinets, reducing the footprint in the installation location.

Technical parameters

Code	OW.PU.5

The heater is available in two capacities: 5L and 10L, with corresponding dimensions and weights. The maximum working pressure is 0.6 MPa, and the electrical input is 1500 W at 230 V. These parameters are essential for correct sizing and selection. The capacity determines the volume of hot water available, while the maximum pressure ensures compatibility with the system's hydraulic conditions. The 1.5 kW power rating indicates the rate at which the unit can heat water, which is important for calculating recovery times and matching the unit to the expected demand.

Installation and connection

Installation requires a secure mounting location with access to a 230 V electrical supply and a cold water inlet. The unit is connected to the water supply via a standard inlet and an outlet for hot water. The inlet and outlet connections are sized according to the unit's flow requirements, ensuring minimal pressure drop. The installer should verify that the mounting surface is stable and can support the unit's weight. The electrical connection must be made by a qualified electrician, ensuring that the circuit is correctly rated for the 1500 W load and that all safety switches and fuses are in place.

Common installation mistakes include incorrect electrical wiring, failure to secure the unit properly, and neglecting to check the inlet and outlet connections for tightness. The unit must be installed in a location that allows for easy access to the manual control and any future maintenance. The system pressure must be within the 0.6 MPa limit to prevent damage to the unit or the surrounding plumbing.

Compatibility and accessories

The heater is compatible with standard domestic water supply systems and can be used in conjunction with thermostatic mixing valves or flow regulators if required. No additional accessories are included with the unit, so installers may need to order separate components such as mounting brackets, electrical cables, or pressure relief valves, depending on local regulations and system requirements. The unit is not listed as compatible with any specific related products in the manufacturer's range.

Technical background for designers

The heater operates by heating water stored in an insulated tank using an electric heating element. The tank is insulated with expanded polystyrene and enclosed in a rigid plastic cover to reduce heat loss. The double corrosion protection system includes a ceramic enamel lining and a magnesium anode, which helps to prevent internal corrosion and prolong the unit's service life. The manual control allows the user to switch the heater on and off, but it does not regulate the temperature automatically. The unit is designed for integration into systems with stable demand and where temperature fluctuations are not a concern.

Material properties such as the thermal conductivity of the insulation and the corrosion resistance of the tank lining are important for long-term performance. The service life and efficiency of the unit are influenced by the quality of the water supply, the frequency of use, and the maintenance of the anode. Designers should consider the unit's dimensions and weight when planning the installation location and structural support.

Service and operation

Regular maintenance is not specified in the technical data, but general best practices include checking the condition of the anode and the integrity of the electrical connections. The tank should be inspected for signs of internal corrosion or leaks. The manual control should be tested to ensure it functions correctly. No specific service intervals are provided, but the unit should be serviced if performance issues arise or if the anode is suspected to be depleted.

Frequently asked questions

Can the EL. 5 EM SUBS. (US) BEST be used in a recirculation system?
It can be used in a recirculation system provided the system pressure does not exceed 0.6 MPa and the flow rate is within the unit's capacity. Additional components such as a circulation pump may be required.

Is it possible to install the heater in a vertical position?
Yes, the heater is designed for vertical installation. However, the mounting location must be stable and able to support the unit's weight.

What is the maximum water temperature it can reach?
The maximum water temperature is not specified in the technical data. The temperature is controlled manually, and the user must monitor it to avoid overheating.

Can the heater be used with a thermostat for automatic temperature control?
The heater does not have a built-in thermostat. It is designed for manual operation only. A separate thermostat would need to be added to the system for automatic temperature regulation.
