The TIH650 Tesla 27-inch immersion heater is a premium-grade hot water heating element designed for deeper domestic cylinders. Featuring a fully Incoloy construction and supplied with an adjustable thermostat, this unit delivers exceptional durability, efficiency, and long-term performance—especially in demanding or hard water environments.
The extended 27" length allows the element to reach deeper into the cylinder, ensuring a greater volume of stored water is heated evenly. This reduces cold zones and improves overall hot water availability, making it ideal for larger households or high-capacity systems.
Constructed entirely from Incoloy, this immersion heater offers superior resistance to limescale build-up, corrosion, and thermal fatigue. Compared to standard copper elements, it maintains performance for longer and requires less maintenance, even under continuous use.
The included thermostat provides accurate temperature control, automatically regulating the heating cycle to maintain safe and efficient operation. With an integrated safety cut-out, it helps prevent overheating and ensures compliance with modern safety standards.
