The Hi-therm LUMIA MINI 15U electric water heater is the most spacious and powerful storage boiler in our compact line, specifically engineered for under-sink installation. Combining maximum capacity with high performance, this model delivers a stable hot water supply for intensive domestic or commercial needs in apartments, large offices, or catering establishments where it is essential to keep all pipe connections hidden inside the furniture.
The appliance is equipped with an enhanced 2000 W heating element, guaranteeing exceptionally fast water heating even at full tank capacity while maintaining rational power consumption. The inner container is built from heavy-duty structural steel (1.8 mm thickness) and coated with a premium protective enamel layer alongside a sacrificial magnesium anode, ensuring maximum corrosion resistance, structural durability, and excellent water hygiene.
User-friendly mechanical controls allow for instant temperature selection via an accurate capillary thermostat, while the enhanced high-density polyurethane thermal insulation (30 mm) works like a thermos to minimize energy dissipation, maintaining excellent operational efficiency in standby mode.
Key Advantages:
• Maximum Capacity in the Line (14.7 L): provides the largest hot water reserve for active domestic or commercial usage while maintaining highly compact casing dimensions.
• Under-Sink Installation: ergonomic, hidden under-counter placement inside the cabinet with top-oriented pipe connections (G 1/2") that saves valuable space and keeps the interior tidy.
• High 2000 W Output: the upgraded heating element delivers remarkably short waiting times for complete tank heating, reducing delays to an absolute minimum.
• Enhanced Insulation (30 mm): a significantly thicker insulation blanket locks heat inside, lowering daily electricity costs and achieving an official European Energy Efficiency Class B.
• Heavy-Duty Corrosion Protection: enhanced dual defense combining extra-thick structural steel (1.8 mm), premium protective enamel lining, and a robust magnesium anode core.
• Precise Control & Safety: reliable capillary thermostat for smooth temperature adjustment up to 75°C, IPX4 splash resistance, and an automatic thermal cut-off system at 93°C.
Hi-therm LUMIA MINI 15U — a perfect balance of European reliability, maximum output, and rapid heating, neatly hidden out of sight.
