The TIH540 11-inch immersion heater is a complete hot water heating solution, supplied with an integrated thermostat and copper pocket, designed for use in domestic hot water cylinders. Built with a durable Incoloy heating element, this unit offers enhanced resistance to limescale and corrosion, making it particularly suitable for areas with hard water.
Immersion heaters provide a reliable method of heating stored water independently of a boiler system. When energised, the Incoloy element heats up and transfers thermal energy directly into the surrounding water within the cylinder. The included adjustable thermostat monitors water temperature and regulates power to maintain safe and efficient operation, preventing overheating.
The Incoloy construction is a key advantage over standard copper elements. It offers superior durability under high temperatures and is less prone to scale build-up, which can otherwise reduce heating efficiency and shorten the lifespan of the element. This makes the TIH540 an ideal choice for both replacement and new installations where long-term reliability is essential.
Supplied with a copper pocket, the thermostat is accurately positioned within the cylinder to ensure precise temperature sensing and control. This helps maintain consistent hot water temperatures while improving energy efficiency.
