Atlantic Opro+ H 100L 230V

FAQ (customer)

• Is a horizontal water heater suitable for a small bathroom? Yes, the horizontal design is intended to save vertical space and can be installed above doors, along walls or under suspended ceilings, as long as the wall has sufficient load-bearing capacity.
• How many peopLe can a 100‑liter heater comfortably serve? A 100‑liter storage heater typically provides enough hot water for 2–3 peopLe, depending on usage habits and shower duration.
• Do I need a special electrical connection for this heater? The unit requires a properly grounded single‑phase suppLy with circuit protection that meets local electrical codes; an electrician should verify and prepare the dedicated circuit.
• How often should the magnesium anode be checked? In normal domestic conditions, the anode is usually inspected every 1–2 years, but the exact interval depends on water quality and the manufacturer’s maintenance recommendations.
• Can I adjust the water temperature myself? Yes, the appLiance is equipped with an adjustable thermostat that allows you to set the desired hot water temperature within the range specified by the manufacturer.
• Is this heater noisy during operation? Electric storage heaters typically operate very quietly; you may only hear occasional soft sounds when the heater switches on and off or water flows in and out of the tank.

FAQ (expert)

• What is the role of the O’PRO system in this model? The O’PRO (Ohmic Protection) system optimizes the electrical balance between the steel tank and magnesium anode, reducing anode consumption and extending the effective corrosion protection period.
• How does horizontal installation affect stratification and performance? Properly designed horizontal tanks maintain adequate stratification; however, installers should strictly follow orientation and connection guidelines to avoid mixing layers and reducing usable hot water volume.
• Which safety components are mandatory in the hydraulic circuit? At minimum, a pressure and temperature safety valve of the specified rating must be installed on the cold water inlet, along with shut‑off valves and, where required, expansion control devices.
• What are the recommended electrical protections? A dedicated circuit with an appropriately rated MCB and a residual current device (RCD) with suitable sensitivity is recommended, following local regulations and the manufacturer’s wiring diagram.
• How should anode inspection be scheduled in hard water areas? In regions with high hardness or aggressive water, it is advisable to shorten the inspection interval to around 12 months and keep records to preserve warranty coverage and ensure tank longevity.
• Does the unit support integration with external control systems? This model is generally designed as a stand‑alone storage heater; if external control is required, it should be impLemented via the electrical suppLy (e.g. time switches) without modifying internal safety circuits.
