Electric water heater Milano, 100L, bottom connection

Product detailed description

Electric water heaters are essential components in modern plumbing systems, particularly in residential and commercial buildings where a consistent supply of hot water is required. The Hydroland Milano 100L model is commonly used in kitchens, bathrooms and utility rooms, where vertical installation is preferred due to limited floor space. It is typically integrated into systems with cold water supply and hot water distribution, and may be used in conjunction with thermostatic mixing valves or circulation pumps. The bottom connection design simplifies installation in tight spaces, such as under sinks or in mechanical rooms, and ensures a neat and compact setup. Installers should ensure that the heater is mounted on a stable, non-combustible surface and that the electrical supply is properly isolated and protected.

The 100L capacity makes this model suitable for households with moderate to high hot water demand, such as small to medium-sized families. The 2000W power rating ensures a reasonable heating time, while the IPX4 rating allows for installation in areas exposed to splashing water, such as bathrooms or laundry rooms. The maximum working pressure of 6 bar indicates compatibility with standard domestic water supply systems. The energy efficiency class C suggests a moderate level of efficiency, which should be considered when selecting the unit for a specific application.

Installation and connection

The Hydroland Milano 100L is designed for vertical installation with a bottom connection, which requires a standard 1/2 inch pipe thread for both inlet and outlet. The unit should be mounted on a stable, level surface and secured to prevent movement. The electrical connection is via a 150cm cable with a European plug, which must be connected to a dedicated 230V-50Hz circuit with appropriate circuit protection. The heater must be fully filled with water before being switched on, and the pressure relief valve must be checked for proper operation. Common installation mistakes include incorrect electrical wiring, failure to secure the unit properly, and neglecting to check the function of the pressure relief valve. Installers should also ensure that the heater is not installed in direct contact with flammable materials and that the surrounding area is well-ventilated.

Compatibility and accessories

This electric water heater is compatible with standard domestic plumbing systems and can be integrated with thermostatic mixing valves, circulation pumps and temperature control systems. It is recommended to install a pressure-reducing valve if the incoming water pressure exceeds 6 bar. The unit does not include a mounting bracket, so one must be ordered separately. No additional accessories are included in the standard package, so installers should ensure that all necessary components, such as pipe fittings and electrical cables, are available before installation. Related products include the Hydroland Milano models with capacities of 30L, 40L, 50L, 80L and 100L, which are suitable for different hot water demands and installation conditions.

Technical background for designers

The Hydroland Milano 100L operates by heating water stored in a stainless steel SS840 heating element, which is controlled by a thermostat with a temperature range of 25°C to 75°C. The internal tank is made of cold-rolled steel with a minimum wall thickness of 1.8mm and is glazed with a minimum of 0.35mm of enamel to prevent corrosion. The tank is insulated with polyurethane foam with a thickness of 20mm, which reduces heat loss and improves energy efficiency. The magnesium anode with a diameter of 20mm and a length of 200mm helps to protect the tank from internal corrosion by sacrificing itself to the corrosive effects of water. The unit is designed for integration into standard domestic hot water systems and is suitable for use with both cold water supply and hot water distribution. The service life and efficiency of the heater depend on the quality of the water supply, the frequency of maintenance and the correct installation of the unit.

Service and operation

Regular maintenance is essential to ensure the long-term performance and safety of the Hydroland Milano 100L. The magnesium anode should be replaced periodically to maintain internal corrosion protection, and the pressure relief valve should be tested weekly to ensure it is functioning correctly. The heater should be turned off and disconnected from the power supply if it is not to be used for an extended period. In the event of a leak, the unit should be immediately disconnected from the power supply and inspected for damage. The thermostat and heating element should be checked for signs of wear or malfunction, and any faults should be addressed by a qualified technician. The IPX4 rating ensures that the unit is protected against splashing water, but it should not be installed in areas with direct water exposure. The heater should not be operated when it is not fully filled with water, as this can cause damage to the heating element and tank.

Frequently asked questions

Can the Hydroland Milano 100L be installed in a bathroom?
Yes, the IPX4 rating allows for installation in areas with splashing water, such as bathrooms, provided that the unit is mounted in a location that is not directly exposed to water.

What is the maximum working pressure of the Hydroland Milano 100L?
The maximum working pressure is 6 bar, which is suitable for standard domestic water supply systems. If the incoming water pressure exceeds this, a pressure-reducing valve should be installed.

What is the recommended temperature range for the thermostat?
The thermostat can be set between 25°C and 75°C, with a thermal cut-off at 93°C ± 3°C to prevent overheating and damage to the unit.

How often should the magnesium anode be replaced?
The magnesium anode should be replaced periodically to maintain internal corrosion protection. The exact interval depends on the quality of the water supply and the usage of the heater.
