Thermowatt - 14" 1 3/4" Incoloy 800 Immersion Heater - 3kW - 340160900000

The Thermowatt Incoloy 800 is a premium, heavy-duty 3kW replacement immersion heater engineered for high-performance domestic water heating applications. Featuring a 14-inch element length, this unit provides optimal heat distribution throughout the mid-to-lower sections of a hot water cylinder. It is built with a specialised 1 3/4" BSP threaded boss, making it an essential, precise fit for specific unvented and vented cylinders that require this non-standard, smaller thread size rather than the more common 21/4" profile.
