ATLANTIC O’Pro Central Domestic HM150 electric water heater 150 l, 2.2 kW, horizontal, class C, 873211

ATLANTIC O’Pro Central Domestic HM150, reference 873211, is an electric storage water heater with a 150-litre tank and 2200 W / 2.2 kW heating output. The model is designed for horizontal wall-mounted installation.

Its 150-litre capacity provides a substantial reserve of domestic hot water. The horizontal configuration is particularly suitable where installation height is restricted and a conventional vertical storage heater is impractical.

The model is equipped with a 2200 W copper immersion heating element and operates from a 220–240 V electrical supply.

According to ATLANTIC technical data, the heat-up time is approximately 3 hours 52 minutes. The appliance can provide approximately 245 litres of mixed hot water at 40 °C.

Tank durability is supported by ATLANTIC O’Pro anti-corrosion technology, designed to reduce electrochemical corrosion and increase the service life of the storage tank.

Additional protection is provided by a magnesium anode. ATLANTIC specifies up to +50% longer tank life thanks to its exclusive anti-corrosion protection system.

The steel tank is protected internally by ATLANTIC Diamond-quality enamel lining, creating a protective barrier between the stored water and the steel tank surface.

High-density insulation helps reduce thermal losses and retain stored-water temperature. The ATLANTIC technical sheet specifies a QPR value of 1.51.

Water temperature is controlled by a mechanical thermostat. This version does not have an external analogue thermometer, but it is equipped with ATLANTIC’s Waterdrop heating light indicator.

The appliance has an IP24 electrical protection rating and is supplied according to ATLANTIC specification with a safety valve and dielectric union.

Energy efficiency class is C. For the horizontal 150-litre version ATLANTIC specifies a 520 mm body diameter/height, 1150 mm length and 610 mm overall installation depth.

Net weight is approximately 37 kg. O’Pro Central Domestic HM150 combines high capacity, a 2.2 kW copper heating element, horizontal installation, Diamond-quality enamel, magnesium-anode protection and ATLANTIC O’Pro anti-corrosion technology.
