ATLANTIC NANTO SWH15A electric water heater 15 l, 2.0 kW, above sink, class A, 821494

ATLANTIC NANTO SWH15A / NANTO AS 15 is a compact electric storage water heater with a 15-litre tank and 2000 W / 2.0 kW heating output. The model is designed for vertical wall-mounted installation above the sink and provides rapid hot-water availability directly at the point of use.

The compact square NANTO design is suitable for kitchens, bathrooms, offices and other locations where a small water heater is required. The 15-litre tank provides a larger hot-water reserve than the 10-litre NANTO model while maintaining compact external dimensions.

The model is equipped with a copper immersion heating element. Its 2.0 kW output provides fast water heating – approximately 18 minutes at a temperature difference of ΔT 35 °C and approximately 27 minutes at ΔT 50 °C.

ATLANTIC O’Pro anti-corrosion technology uses an ohmic resistor to balance the electrical potential between the tank and the heating element. This construction reduces the load on the magnesium anode and helps strengthen tank protection against electrochemical corrosion.

Additional tank protection is provided by a magnesium anode and high-quality Diamond-quality ceramic glass lining. A specific flange lip gasket helps prevent unprotected metal surfaces around the flange from coming into direct contact with water.

High-density CFC-free polyurethane thermal insulation reduces heat losses and helps maintain the temperature of stored hot water for longer. Energy consumption over 24 hours at 65 °C is 0.58 kWh.

A high-efficiency cold-water inlet diffuser introduces incoming water gradually and limits unnecessary mixing with the already heated water inside the tank, helping make more effective use of the available hot-water volume.

Water temperature is adjusted using a front mechanical control knob. The adjustment range is approximately 15–65 °C, while the factory temperature setting is 65 °C.

NANTO provides Eco and Absence modes. Eco mode is intended for economical everyday operation, while Absence mode helps reduce unnecessary energy consumption during extended periods when hot water is not required.

Front light indicators provide information about the heating process and hot-water availability. The appliance also has automatic thermal safety protection against excessive temperature rise.

According to ErP data for product code 821494, the energy efficiency class is A, the declared load profile is XXS and water-heating energy efficiency is 35%. Annual electricity consumption is 527 kWh and sound power level is 15 dB.

ATLANTIC NANTO SWH15A measures 387 × 360 × 321 mm (height × width × depth) and has a net weight of 8.0 kg. It operates from a 230 V / 50 Hz supply, has 1/2" water connections, IP24 protection and an electrical cable with Euro plug. ATLANTIC specifies a 5-year tank warranty subject to the manufacturer's warranty conditions.
