Description
Ariston 15L Water Geyser (Andris) – 15RS
The Ariston 15L Water Geyser Andris 15RS is a compact electric storage water heater designed to provide convenient hot water for everyday household use. Combining a 15-litre storage capacity with a powerful 1200W heating element, adjustable temperature regulation and a compact wall-mounted design, the Ariston Andris 15RS is well suited for bathrooms, kitchens and other areas where a dependable supply of hot water is required. The model is part of Ariston’s Andris RS range and is designed for installation above the sink. Ariston’s official technical information identifies the 15/3 model as a 15-litre, 1.2kW electric storage water heater.
15-Litre Storage Capacity
The Ariston 15L Water Heater provides a 15-litre storage capacity, making it a practical choice for applications where hot water is required without installing a larger tank. The compact capacity is particularly suitable for individual bathroom use, wash basins, kitchens and other point-of-use applications.
The stored water is heated and maintained inside the insulated tank, allowing the Ariston Andris RS 15 to provide hot water when required. Its compact size also makes it easier to accommodate in areas where installation space is limited.
Powerful 1200W Heating
The Ariston Electric Geyser uses a 1200W heating element, providing efficient heating performance for its 15-litre capacity. Ariston’s official technical specifications list a heating time of approximately 44 minutes for a 45°C temperature increase on the 15/3 model.
This makes the Ariston Andris 15RS suitable for everyday hot-water requirements while keeping the appliance relatively compact. The adjustable thermostat allows the user to regulate the water temperature according to their preferred level.
Adjustable Temperature Regulation
The Ariston 15L Water Geyser features temperature regulation through a mechanical thermostat and control knob. This allows users to select the desired heating level rather than relying on a fixed temperature setting.
The thermostat is designed to maintain control over the water temperature during normal operation, while the integrated indicator light provides a simple visual indication of the heating status. The official product information confirms that the Andris RS 15/3 has an adjustable thermostat and an indicator light.
Glass-Lined Inner Tank
A major feature of the Ariston 15L Water Heater is its glass-lined inner tank. The tank is designed to provide protection against corrosion while supporting long-term everyday use.
The Andris RS range also uses ecological polyurethane insulation around the tank to help reduce heat loss. The inner tank is tested to a pressure of up to 16 bar, while the operating safety system includes a pressure safety valve designed for up to 8 bar.
Magnesium Anode Protection
The Ariston Andris RS 15 incorporates an oversized magnesium anode as part of its tank protection system. The anode provides additional protection for the tank by helping reduce corrosion of the metal components.
This combination of a glass-lined tank and magnesium anode makes the Ariston Electric Geyser a practical choice for users looking for a storage water heater designed with tank protection in mind.
Compact Wall-Mounted Design
The Ariston Andris 15RS is designed as a compact wall-hung water heater and can be installed above the sink. Its relatively small dimensions make it suitable for bathrooms and other spaces where installation area is limited.
The exact Ariston 15L Water Geyser dimensions are approximately 36 × 36 × 34.6 cm, while the official technical information gives a weight of approximately 7.4 kg for the Andris RS 15/3.
Energy-Efficient Everyday Heating
The Ariston 15L Water Heater has an A energy efficiency class under the applicable European ErP product classification, with the official EPREL fiche listing annual electricity consumption of 522 kWh under the specified test conditions.
Overall, the Ariston Andris 15RS combines a compact 15-litre capacity, 1200W heating power, adjustable temperature control, glass-lined steel tank, magnesium anode, polyurethane insulation and pressure safety protection. For households looking for a compact Ariston Electric Geyser for everyday hot-water requirements, the Andris 15RS offers a practical combination of Italian design, controlled heating and space-efficient installation.
