SingleLine Electric Water Heater: Efficiency and Durability in a Single Line
A revolution in design, an investment in trust.

Designed to last. Built with intelligence.
Unlike traditional water heaters that have three welds (one longitudinal and two on the lids), the SingleLine electric water heater has been designed with a single circumferential weld in the center of the tank. This innovation drastically reduces critical points of wear and leakage, providing greater durability, efficiency, and long-term reliability.
SingleLine Advantages
🔩 Less is more: just one weld
Most electric water heaters are made from a single sheet of metal welded lengthwise and sealed at both ends, creating three seams. The SingleLine water heater is made from two perfectly curved halves joined by a single weld across their diameter, eliminating longitudinal seams and welds on the ends.
🛡️ Longer lifespan
Each weld is a potential point of corrosion or failure. With only one central joint, SingleLine minimizes these risks, significantly extending the equipment's lifespan.
🌡️ Structural and thermal efficiency
The symmetrical and more robust design allows for a uniform distribution of internal pressure, better temperature retention, and a lower risk of deformation over time.
🧰 Less maintenance, greater reliability
Fewer welds mean fewer problems. With SingleLine, you invest in peace of mind: fewer breakdowns, fewer repairs, less worry.

Electrical Resistance in Incoloy 840 with Obsidian Coating: Technology that Raises the Standard
The durability and efficiency of an electric water heater depend on more than just the tank. The heating element is the heart of the system , and in the SingleLine water heater, it's constructed with high-performance materials: Incoloy 840 and a special obsidian coating.

Why Incoloy 840? 🛡️ Superior Corrosion Resistance Incoloy 840 is a nickel-iron-chromium alloy designed to withstand high temperatures and harsh environments, including hard water with high chlorine, calcium, or magnesium content, such as Chilean water. 🔥 Exceptional Thermal Stability Unlike conventional stainless steel heating elements, Incoloy 840 maintains its structural integrity at higher temperatures, allowing for more efficient heating and a significantly longer lifespan. 🔧 Reduced Risk of Overheating Failures Thanks to its excellent thermal conductivity, heat is distributed more evenly, reducing hot spots that could damage the heating element.
What about the obsidian coating? 🌑 Next-generation ceramic protection The obsidian coating is a vitrified ceramic treatment with nanotechnology that isolates the heating element from direct contact with water, preventing limescale buildup and improving system hygiene. 🧼 Non-stick and anti-scale This coating acts as a barrier that hinders the adhesion of minerals and bacteria. Less limescale = better performance + less maintenance. ♻️ Greater energy efficiency By reducing residue accumulation, the heating element maintains its thermal efficiency for much longer, consuming less energy to heat the same amount of water.
A Powerful Combination The synergy between Incoloy 840 and the obsidian coating makes this heating element one of the most advanced on the market. ✔ Cleaner ✔ Safer ✔ Longer lasting (10 times longer than a 316L stainless steel element, and 5 times longer than an uncoated Incoloy 840 steel element with nanotechnology). Ideal for those looking for a water heater that will function flawlessly for many years, even under demanding conditions.
⚙️ RTEK Magnesium Anode – Advanced Technology in Heater Protection
The RTEK magnesium anode represents the new generation of magnesium anodes designed to extend the lifespan of water heaters. Thanks to its rare earth composition and optimized structure, it offers superior corrosion protection.
🧪 Composition and Manufacturing
Mold casting with high purity magnesium, resistance and structural solidity.
It contains unique rare earth elements (such as lanthanum and cerium) that increase corrosion resistance.
Integrated electronic micromodules reduce rod consumption, extending its effectiveness.
📈 Comparison of Duration – Estimated useful life according to water type:

🛡️ Key Benefits
✅ Greater protection against corrosion even in low quality water.
✅ Longer lifespan compared to conventional rods.
✅ Less maintenance and greater reliability of the heating system.
Termic electric water heaters , whether small or industrial, are electric water heaters of the highest quality, at the best price, and have been designed in the same way that we design our solar equipment, that is, they are designed to withstand the pressures and qualities of water in Chile , in a very robust way, with the best materials available in the world, and with the best components. We settle only for the best, in order to pass on confidence and quality to our customers. You will not find better water heaters on the market or at more competitive prices!
Uses
The 80 and 120 litre thermoses are designed for houses or apartments with 3 and 4 people respectively.
The 200 and 300 litre thermoses are recommended for large houses with 5 or more people.
We always recommend using mixing valves on all electric water heaters as a safety measure and as an energy saving measure.
Both the 500 litre @ 9 kW electric water heater and the 300 litre @ 54 kW electric water heater are exclusively designed for the industry due to their three-phase 380V connection, ideal for mining, changing rooms, industrial kitchens, staff showers, and similar, where excellent equipment is required due to its large size and high power.
