The TIH640 11-inch immersion heater is a high-performance hot water heating element featuring an all Incoloy construction, supplied complete with an adjustable thermostat. Designed for durability and efficiency, this unit is ideal for domestic hot water cylinders, particularly in areas with hard water where standard elements are prone to scaling.
Unlike traditional immersion heaters that combine different materials, the TIH640 features an all Incoloy build, offering superior resistance to limescale, corrosion, and thermal stress. This ensures a longer service life and more consistent performance, even under demanding conditions.
When powered, the heating element transfers heat directly into the stored water within the cylinder. The included thermostat regulates temperature by cycling the element on and off as needed, maintaining safe operating conditions and preventing overheating. Its accurate temperature control helps improve energy efficiency while ensuring a reliable supply of hot water.
The 11" length makes this immersion heater suitable for standard domestic cylinders, providing effective heating without excessive energy use.
