What it is
The FLOW REGULATOR TYPE E-W 15 L LIME I/C AD is a Worcester Bosch flow regulator, supplied under part number 87161129010. It sits in the water circuit of the appliance and controls the rate at which water passes through, which in turn affects how the appliance delivers hot water. The lime designation identifies it as the variant intended for lime-bearing (hard water) installations.
Signs this part needs replacing
- Hot water flow rate at the taps is noticeably lower than it used to be
- Flow is erratic, surging or inconsistent between draw-offs
- Limescale or debris is visible on the regulator when it is removed for inspection
- Flow-related faults or interruptions to hot water production during a draw-off
Before you order
- Confirm the appliance model from the data badge, as the regulator is specific to the Greenstar Heatslave HE 12/18 Internal
- Check the existing regulator against the part number 87161129010 and the Type E-W marking before ordering
- Inspect the surrounding pipework and seals for scale or damage while access is available
- Verify the water condition on site, as the lime variant suits hard water supplies
