Atlantic Nanto Lite 2kW 15L Above Sink Electric Water Heater (MPN: AH821548) is a space‑saving unvented hot water heater designed for mounting above a basin or sink to provide localised hot water on demand. With a 15 litre glass‑lined tank, 2kW copper immersion element and high‑density polyurethane insulation, it is ideal for kitchens, cloakrooms, offices and light‑commercial washrooms where a full‑size cylinder is not required.

Key Features

• 2kW copper immersion heater – submerged element delivers fast reheat times and responsive hot water performance.
• 15 litre diamond‑quality enamel glass tank – glass‑lined steel tank offers excellent corrosion resistance and durability.
• Magnesium anode protection – sacrificial anode reinforces internal protection and can extend tank life by up to 50% versus basic designs.
• Unvented, mains‑pressure design – supplies hot water at mains pressure without the need for a separate cold water cistern.
• High‑density CFC‑free PU insulation – thick polyurethane foam around the tank minimises standing heat losses and boosts efficiency.
• Analog front dial – simple control to adjust set temperature and select eco or vacation mode quickly.
• Eco mode (~55°C) – energy‑saving setpoint that balances comfort, reduced limescale formation and lower running costs.
• Vacation mode (~7°C) – frost‑protect/holiday mode that cuts energy consumption while protecting the unit when not in regular use.
• ErP A energy rating – high efficiency oversink configuration with very low standing losses for its size.
• Compact over‑sink format – designed specifically for mounting above a sink or basin, with outlets directly below.

Performance & Applications

• Typical applications: domestic kitchens and bathrooms, office tea points, staff washrooms, classrooms, clinics and small hospitality sites needing local hot water.
• 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 (from cold feed).
• Standing losses: low daily energy loss thanks to high‑density insulation, supporting the A‑rated ErP classification.
• Best suited where: there is no existing hot water distribution or where long pipe runs from a central source would cause delay and water wastage.

Installation Notes

• Should be installed by a competent person in line with local plumbing and wiring regulations and the Atlantic installation manual.
• As an unvented oversink heater, it must be fitted with the appropriate safety kit (pressure relief valve, expansion control, non‑return/check valves) as specified by the manufacturer.
• Mount securely above the sink on a suitable wall, with sufficient space for plumbing connections, electrical access and future maintenance (including anode inspection).
• Use eco and vacation modes via the front dial to optimise energy use, reduce limescale risk and extend the life of the appliance.
