ATLANTIC O’Pro SMALL PCSB10 L electric water heater 10 l, 2.0 kW, under sink, class B, 821180

ATLANTIC O’Pro SMALL PCSB10 L / PCSB 10 is a compact electric storage water heater with a 10-litre tank and 2000 W / 2.0 kW heating output. It is designed for vertical wall-mounted installation under the sink and provides rapid hot-water availability directly at the point of use.

The compact O’Pro Small casing is particularly suitable for kitchens, offices, small bathrooms and other locations where installation space is restricted. Its 10-litre tank provides a local supply of hot water without the need for a large central storage water heater.

The model is equipped with a copper immersion heating element. Its 2.0 kW output provides very rapid water heating, with ATLANTIC international technical documentation specifying approximately 19 minutes at a temperature rise of ΔT 50 °C for the 10-litre under-sink model.

ATLANTIC O’Pro anti-corrosion technology uses an ohmic resistor to balance electrical potential between the tank and heating element. The system reduces galvanic current, helps extend magnesium-anode service life and strengthens tank protection against electrochemical corrosion.

Additional tank protection is provided by a magnesium anode and high-quality Diamond-quality glass lining. The lining protects the inner steel surface against direct water exposure and contributes to long-term reliability.

A specially designed flange lip gasket helps reduce the risk of corrosion around the flange. Tank protection therefore combines the glass lining, magnesium anode, O’Pro resistor and protected flange design.

High-density CFC-free polyurethane insulation reduces heat losses and helps retain stored-water temperature for longer. ATLANTIC technical documentation specifies approximately 0.63 kWh/24 h at 65 °C for the 10-litre under-sink version.

A high-efficiency cold-water inlet helps reduce unnecessary mixing of incoming cold water with already heated water, allowing more efficient use of the available stored hot water.

Temperature is adjusted by a simple and reliable mechanical thermostat. On the under-sink PCSB model the control knob is positioned at the top of the appliance for convenient access after installation.

The appliance includes a heating light indicator, automatic thermal safety protection, pressure relief valve and dielectric union. The electrical cable is supplied with a Euro plug.

According to the official EPREL product fiche for code 821180, the energy efficiency class is B, declared load profile XXS and water-heating energy efficiency 33%. Annual electricity consumption is 552 kWh, the ErP thermostat setting is 64.04 °C and indoor sound power level is only 15 dB.

The ATLANTIC technical sheet specifically listing article 821180 gives dimensions of 456 × 255 × 262 mm and a net weight of 6.5 kg. The model operates from a 230 V / 50 Hz supply, the under-sink version has an IP24 protection rating, and ATLANTIC provides a 5-year tank warranty subject to the manufacturer's warranty conditions.
