ATLANTIC O’Pro SMALL PCRB15 L electric water heater 15 l, 1.6 kW, above sink, class B, 821181

ATLANTIC O’Pro SMALL PCRB15 L / PCRB 15 is a compact electric storage water heater with a 15-litre tank and 1600 W / 1.6 kW heating output. It is designed for vertical wall-mounted installation above the sink and provides rapid hot-water availability close to the point of use.

The 15-litre O’Pro Small is suitable for kitchens, bathrooms, offices, workshops and other locations where a local hot-water source is required without a large storage tank. Its compact design makes efficient use of restricted installation space.

The model is equipped with a copper immersion heating element. Its 1.6 kW output heats the 15-litre water volume rapidly – approximately 14 minutes at ΔT 20 °C and approximately 35 minutes at ΔT 50 °C.

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

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

A dedicated flange lip gasket helps reduce corrosion around the flange area. Tank protection therefore combines glass lining, a magnesium anode, the O’Pro resistor and a protected flange design.

High-density CFC-free polyurethane insulation reduces heat losses and helps retain stored-water temperature for longer. Energy consumption at 65 °C for the 15-litre above-sink configuration is approximately 0.58 kWh/24 h.

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

Water temperature is controlled by a simple and reliable mechanical control knob. On O’Pro Small above-sink models, the control is located at the bottom of the appliance for convenient access.

A built-in heating light indicator shows when the heating element is operating. Safety equipment also includes a pressure relief valve, dielectric union and thermal safety protection.

According to the official EPREL product fiche for code 821181, the water-heating energy efficiency class is B, the declared load profile is XXS and water-heating efficiency is 34%. Annual electricity consumption is 542 kWh, the ErP thermostat setting is 72.83 °C and indoor sound power level is only 15 dB.

ATLANTIC’s current O’Pro Small technical documentation gives approximately 400 × 338 × 348 mm dimensions for the 15-litre above-sink configuration, a 7.5 kg net weight and a 78 mm flange opening. The model operates from a 230 V / 220–240 V supply and the above-sink configuration has an IP25 protection rating.
