What it is
The Worcester Bosch 8716121838 Plate is a plate component for the plate heat exchanger assembly used across the Worcester Bosch Greenstar boiler range. It sits within the heat exchanger group of gas boiler spares, where the heating circuit and the domestic hot water circuit are kept separate while heat passes between them. It is listed for Greenstar 2000 Combi, 4000 Combi and 4000 System models.
Signs this part needs replacing
- Reduced domestic hot water temperature or inconsistent hot water delivery at the tap
- Scale or sludge build-up restricting flow through the plate stack
- Visible weeping or staining around the plate heat exchanger area
- Overheating, kettling or lockout during hot water draw-off
- Poor heat transfer between the primary and domestic hot water circuits
Before you order
- Confirm the boiler model and GC number against the fitment list before ordering
- Check whether the appliance is the NG or LPG variant
- Inspect the existing plate and surrounding seals for damage before dismantling
- Isolate the gas, water and electrical supplies before any work on the heat exchanger
