Electric water heater Milano, 20L, bottom connection

Product detailed description

Electric water heaters are essential components in many plumbing systems, particularly in compact spaces where traditional tank systems are not feasible. The Hydroland Milano OW.MIL.D20 is designed for vertical installation with bottom connection, making it suitable for under-sink or wall-mounted applications. The unit is compatible with standard electrical and plumbing systems and requires minimal space due to its compact dimensions. Installers should ensure that the installation location allows for proper ventilation and access for maintenance.

The 20L capacity and 2000 W power rating make this model suitable for moderate hot water demand. The IPX4 rating indicates protection against splashing water, which is essential for installations in areas with potential water exposure. The maximum working pressure of 6 bar ensures compatibility with standard domestic water supply systems. The energy efficiency class B indicates moderate efficiency, which should be considered when selecting the unit for a specific application.

Installation and connection

The Hydroland Milano OW.MIL.D20 requires vertical installation with bottom connection. The installation process involves securing the unit in a suitable location, connecting the water supply to the bottom inlet, and routing the electrical supply to the built-in 150 cm cable with a European plug. The inlet and outlet connections are standard for domestic plumbing systems. Installers should verify that the unit is fully filled with water before energising it and ensure that the electrical supply is correctly rated for the 2000 W load. Common installation mistakes include incorrect orientation, failure to secure the unit properly, and neglecting to check the pressure relief valve function.

Compatibility and accessories

The OW.MIL.D20 is compatible with standard plumbing and electrical systems. It is recommended to use a pressure relief valve and a separate circuit breaker for electrical safety. The unit does not require additional accessories for basic operation, but a mounting bracket may be necessary for wall installation. Installers should ensure that the electrical supply is protected by a suitable circuit breaker and that the water supply is compatible with the unit’s pressure and flow requirements.

Technical background for designers

The Hydroland Milano OW.MIL.D20 operates by heating water stored in an insulated tank using a stainless steel heating element. The tank is made of cold-rolled steel with a minimum 1.8 mm wall thickness and a glazed coating with a minimum 0.35 mm thickness. The insulation material is polyurethane with a 20 mm thickness, which helps to reduce heat loss. The unit is designed to maintain a stable temperature within the range of 25°C to 75°C, with an overheat protection mechanism that activates at 93°C. The integration into the system depends on the available electrical and water supply infrastructure. 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 magnesium anode.

Service and operation

Regular maintenance is essential to ensure the long-term performance of the Hydroland Milano OW.MIL.D20. The magnesium anode should be replaced periodically to prevent corrosion of the internal tank. The pressure relief valve should be checked weekly to ensure it is functioning correctly. In the event of a leak, the unit should be immediately disconnected from the power supply. If the unit is not to be used for an extended period, it should be disconnected from the electrical supply to prevent unnecessary energy consumption and potential damage.

Frequently asked questions

Can the Hydroland Milano OW.MIL.D20 be installed in a bathroom?
Yes, the unit has an IPX4 rating, which provides protection against splashing water. It is suitable for installation in areas with potential water exposure, such as bathrooms, provided that the installation location allows for proper ventilation and access for maintenance.

What is the maximum working pressure of the OW.MIL.D20?
The maximum working pressure is 6 bar, which is compatible with standard domestic water supply systems. Installers should ensure that the water supply pressure does not exceed this limit to avoid damage to the unit.

What is the recommended temperature range for operation?
The thermostat allows temperature regulation between 25°C and 75°C. The unit is designed to maintain a stable temperature within this range, and the overheat protection mechanism activates at 93°C to prevent overheating.

What is the recommended maintenance schedule for the OW.MIL.D20?
The magnesium anode should be replaced periodically to prevent corrosion of the internal tank. The pressure relief valve should be checked weekly to ensure it is functioning correctly. If the unit is not to be used for an extended period, it should be disconnected from the electrical supply.
