What it is
This is a Viessmann Type A flow regulator, supplied in white and black and rated at 10L, part number 7828752. It is a water level limiter used within the hydraulic circuit of Viessmann Vitodens 100-W combi appliances. Its function is to regulate the flow of water through the appliance so the boiler's control system sees the intended rate on the relevant circuit.
Signs this part needs replacing
- Reduced or inconsistent hot water flow at the taps despite adequate supply pressure elsewhere.
- The boiler fails to fire reliably on a hot water draw-off.
- Hot water output fluctuates or cuts out during use.
- The appliance shuts down or locks out when hot water is demanded.
Before you order
- Confirm the appliance model and serial number against the fit list above, as this regulator is listed for specific Vitodens 100-W combi variants.
- Check the existing regulator's type marking and flow rating match Type A and 10L.
- Verify the part number 7828752 against the number marked on the component being replaced.
- Inspect the surrounding hydraulic connections for debris or scale before fitting, as contamination can affect regulator operation.
