Atlantic Nanto Lite 2kW 15L Under Sink Electric Water Heater

Atlantic Nanto Lite 2kW 15L Under Sink Electric Water Heater (MPN: AH821549) is a compact unvented hot water heater engineered to fit neatly under a sink and deliver almost instant hot water at the point of use. With a 15 litre storage tank and 2kW heating element, it is ideal for kitchens, utility rooms, office tea points and small washrooms where a full‑size cylinder is not required.

Key Features

• 2kW heating element – provides fast heat‑up and quick recovery for everyday handwashing, dishwashing and light‑duty hot water needs.
• 15 litre storage capacity – sized for single or multiple outlets with moderate draw‑off, such as a kitchen sink and basin.
• Under‑sink, wall‑mounted design – compact footprint installs discreetly below the sink to save space and minimise pipe runs.
• Unvented point‑of‑use heater – delivers mains‑pressure hot water without the need for a separate feed tank.
• Diamond enamel glass‑lined tank – corrosion‑resistant internal coating for durability and long service life.
• Magnesium anode protection – sacrificial anode helps protect the tank against corrosion, especially in harder water areas.
• High‑density CFC‑free insulation – polyurethane foam around the tank reduces standing heat losses and improves efficiency.
• Manual control with eco and vacation modes – front analogue dial for temperature setting, eco 55°C mode and holiday 7°C mode for energy savings.
• ErP B hot water rating – energy‑efficient design with low standing losses for its size and duty.
• 2‑year manufacturer warranty – subject to Atlantic terms and correct installation.

Performance & Applications

• Typical use: hot water for sinks and basins in homes, offices, shops, small cafés and similar light‑commercial settings.
• Heat‑up times: indicative heat‑up time around 18 minutes for a 35°C temperature rise and around 27 minutes for a 50°C rise.
• Energy consumption: typical standing energy consumption about 0.58 kWh per 24 hours at standard test conditions.
• Best suited to: locations with no existing hot water distribution or where long pipe runs from a central cylinder would cause delay and waste.
