The Hi-therm LUMIA TECH 100 Dry storage electric water heater is an uncompromising flagship in our line of modern flat boilers, specifically engineered to provide a stable, uninterrupted hot water supply for large households, countryside cottages, and spacious apartments. This model perfectly combines innovative engineering solutions, intelligent controls, and a premium design that seamlessly integrates into any contemporary interior.
The primary advantage of this water heater is its ultra-slim Flat Design casing. By utilizing a system of two interconnected internal tanks, engineers achieved incredibly compact dimensions: the total depth of the appliance, including the mounting brackets, is a mere 330 mm. This allows the spacious 100-liter water heater to be easily mounted inside narrow niches, utility closets, behind false walls, or in the limited spaces of small bathrooms where a classic round boiler would consume most of the room.
Water heating is driven by the advanced Double Dry Heat technology, featuring two independent "dry" heating elements with a total output of 2000 W. These heating elements are enclosed in special protective enameled sleeves (flanges) and are completely isolated from direct contact with water. This solution drastically reduces scale accumulation on the elements, protects them from burning out, and eliminates the risk of electrical current leakage to the casing. The system is ideal for regions with hard, highly mineralized, or well water, ensuring an extended operational lifespan and simplifying routine servicing.
The appliance is operated via an intelligent electronic panel with a sleek, mirrored touch-screen LED display. Users can choose between power levels: an eco-mode (1000 W) to reduce the load on older electrical wiring, or a high-speed mode (2000 W) for the fastest possible heating of the entire water volume. The built-in Smart Timer function allows users to schedule the boiler's operation, making it perfect for owners of dual-tariff meters ("night tariff") and helping to slash electricity costs by up to 40%.
The casing is equipped with an enhanced, eco-friendly polyurethane foam thermal insulation blanket with a thickness of 35 mm. This works on the principle of a thermos, keeping the water hot for hours without triggering the heating elements. For added reliability, a built-in non-volatile memory automatically restores all user-defined settings and modes following sudden power surges or grid blackouts.
Key Technological Advantages:
• Ultra-Slim Flat Format: A depth of just 330 mm allows you to utilize every inch of space efficiently, mounting the appliance inside compact furniture cabinets or plumbing niches.
• Double Dry Heating Technology: Two independent heating elements inside protective sleeves boast a lifespan several times longer than conventional immersion elements, as they are fully shielded from scale and corrosion.
• Flexible Power Optimization (1000 W / 2000 W): Gives you the freedom to choose the operating mode based on your home's electrical grid status or your current need for heating speed.
• Smart Programming & Timer: Allows you to set automated water heating to an exact time, significantly saving your budget by utilizing cheap night-rate electricity.
• European Energy Efficiency Class B: A thick 35 mm layer of high-density insulation minimizes daily standby heat losses.
• Anti-bact Protection (Legionella Control): A special thermal disinfection mode heats the water inside the tank to 85°C, completely destroying harmful microorganisms, preventing stagnation, and eliminating unpleasant odors.
• Comprehensive Safety System: Includes reliable anti-frost protection (automatically heats water to 10°C if the room temperature drops below 5°C), dry-heating prevention, and multi-level overheat protection.
Hi-therm LUMIA TECH 100 Dry — uncompromising comfort, advanced safety, and maximum durability for your family.
| Technical Parameter | Official Value and Engineering Explanation |
|---|---|
| Number & Type of Heating Elements | 2 x Dry (Dry Heavy Duty) — Two independent heating elements shielded from direct water contact by enameled steel sleeves. If one element fails, the boiler continues to operate on the second one. |
| Nominal Power Output | 1000 W / 2000 W (Step Regulation) — Allows switching between two operational modes: 1 kW for temperature maintenance or weak wiring, and 2 kW for maximum heating speed. |
| Actual Nominal Volume | 91.8 Liters — The optimized internal capacity of the dual interconnected tank system, ensuring an ample supply of hot water for a family of 3–4 people without long waiting periods. |
| Insulation Thickness & Type | 35 mm (High-Density Polyurethane) — An enhanced, CFC-free thermal insulation layer made of eco-friendly material. It minimizes daily standby heat loss by acting like a thermos. |
| Operating Temperature Range | 30 °C to 75 °C — Smooth electronic adjustment with 1-degree precision. Features an automated Anti-bact mode that heats up to 85 °C for thermal disinfection. |
| Tank Material & Construction | Enameled Structural Steel (1.8 mm) — Heavy-duty inner tank walls designed to withstand high working pressure. Coated with a proprietary finely dispersed glass enamel to protect welds. |
| Corrosion Protection Core | Oversized Magnesium Anode (Ø22x234 mm) — A protective element with a high content of pure magnesium that neutralizes water aggressiveness and prevents hard scale formation on the walls. |
| Appliance Weight (Net / Gross) | 36.6 kg / 41.3 kg — The solid net weight confirms the use of genuine thick structural steel rather than lightweight budget alloys. |
| External Dimensions (W x D x H) | 520 x 330 x 1181 mm — Unique Flat-format aspect ratio. A depth of only 33 cm allows the boiler to be fully integrated into standard kitchen cabinets or plumbing shafts. |
| Hydraulic Connection | G 1/2" (Bottom Connection) — Standard thread diameter for connecting cold water (blue marker) and hot water (red marker) inlets using flexible hoses or pipes. |
| Protection & Safety Rating | IPX4 (Splash-Proof) / Safety Thermostat at 93 °C — Complete protection of electronic components against moisture and dust. A built-in thermal relay cuts off power instantly in case of critical overheating. |
