Atlantic OPro Small electric boiler 15L PCSB

The Atlantic O'Pro Small 15 L PCSB electric water heater is a compact unit designed specifically for under-sink installation, supplying hot water to a single point of use. Thanks to its small dimensions, it fits perfectly inside kitchen cabinets, saving space while maintaining a clean and integrated appearance.

The heater features a high-reliability copper heating element that provides fast, even heating and excellent resistance to limescale buildup. Longevity is further enhanced by the magnesium anode and the unique O’Pro (Ohmic Protection) technology, which doubles the anode’s service life. A special electrochemical module between the heating element and the anode reduces anode wear and offers long-term corrosion protection.

As a result, maintenance is required less frequently — approximately once every two years — significantly reducing operating costs. The 2000 W copper heating element heats water up to 63°C in just 26 minutes, consuming roughly 870 Wh per cycle, making it one of the most efficient compact heaters available.

The inner tank is coated with zirconium-reinforced enamel, providing exceptional resistance to chemical exposure and temperature fluctuations. Thick polyurethane insulation minimizes heat loss to only 5–6°C per day, allowing the heater to retain hot water for extended periods without reactivation.

The unit has a clean, minimalist design, operates silently and includes an external temperature control knob for easy use. The manufacturer provides 5 years warranty on the tank and 2 years on the electrical components.

Atlantic also maintains one of the largest service networks, ensuring fast and reliable support whenever needed.
