What it is
The Worcester Bosch 87445030100 is a fusing element set rated T0.5, T1.6, T2.5 and T3 at 15A. It sits within the element section of the appliance, where the element raises the temperature of the stored water in the cylinder so it can be drawn off for radiators and domestic hot water use, holding that temperature once reached. The set is a Worcester Bosch electronics and controls component used across the Greenstar range of combi and condensing boilers.
Signs this part needs replacing

- The appliance cuts out repeatedly or resets without an obvious fault code
- The element fails to heat the stored water or cannot hold its set temperature
- A fuse in the element circuit has ruptured and blows again after replacement
- Intermittent operation that clears and returns as the appliance warms up
