ATLANTIC NANTO SWH30A electric water heater 30 l, 2.0 kW, over-sink installation, 831226
ATLANTIC NANTO SWH30A electric water heater 30 l, 2.0 kW, above sink, class C, 831226
ATLANTIC NANTO SWH30A / NANTO AS 30 is a compact electric storage water heater with a 30-litre tank and 2000 W / 2.0 kW heating output. The model is designed for vertical wall-mounted installation above the sink and provides hot water directly close to the point of use.
The 30-litre NANTO is the largest model in this compact range and provides considerably more stored hot water than the 10- and 15-litre versions. It is suitable for kitchens, bathrooms, offices and other locations requiring a compact but higher-capacity water heater.
The model is equipped with a high-quality copper immersion heating element. Its 2.0 kW output provides rapid water heating: approximately 37 minutes at ΔT 35 °C and approximately 53 minutes at ΔT 50 °C.
ATLANTIC O’Pro anti-corrosion technology uses an ohmic resistor to help balance the electrical potential between the magnesium anode and heating element. This reduces galvanic current, extends magnesium-anode service life and strengthens tank protection against corrosion.
Additional tank protection is provided by a magnesium anode and durable Diamond-quality ceramic glass lining. ATLANTIC also uses a dedicated flange gasket that helps protect metal around the flange from direct contact with water.
High-density CFC-free polyurethane insulation helps retain stored water temperature and reduce heat losses. Energy consumption over 24 hours at 65 °C is 0.84 kWh.
An optimised cold-water inlet diffuser directs incoming water to limit unnecessary mixing with the already heated water in the tank. This helps make more efficient use of the available hot-water reserve.
Water temperature is adjustable using a convenient external mechanical control knob. ATLANTIC specifies an adjustment range of approximately 7 to 65 °C, allowing the temperature to be adapted to individual requirements.
NANTO provides Eco and Absence/Frost functions for more economical operation. The anti-frost position maintains a safe minimum temperature during extended periods away while reducing unnecessary electricity consumption.
The water heater includes operating and heating indication as well as automatic thermal safety protection against excessive operating temperature.
According to ErP data for product code 831226, the energy efficiency class is C, the load profile is S and water-heating energy efficiency is 32%. Annual electricity consumption is 576 kWh, the ErP thermostat setting is 55 °C and sound power level is only 15 dB.
ATLANTIC NANTO SWH30A measures 467 × 440 × 388 mm (height × width × depth) and has a net weight of 11.8 kg. It operates from a 220–240 V / 230 V supply, uses 1/2" water connections and has an IP24 protection rating. ATLANTIC specifies a 5-year tank warranty subject to the manufacturer's warranty conditions.
