What it is
The Viessmann cylinder load pump complete, designated VIUP15-30 CIL2, is the circulating pump assembly that moves primary water through the domestic hot water storage cylinder on Vitodens 111-W storage combi boilers. It is supplied by Viessmann as a complete pump unit for the cylinder charging circuit. The pump maintains the flow required to bring the stored hot water cylinder up to temperature during a draw-off.
Signs this part needs replacing
- Domestic hot water runs lukewarm or cold while the heating circuit still works
- The storage cylinder fails to reach temperature, or recovery after draw-off is very slow
- Pump runs hot, is noisy, or emits grinding or humming noises on cylinder charge
- Pump body shows seepage or weeping around the housing or connections
- Pump fails to run at all when the cylinder charge demand is present
Before you order
- Confirm the appliance variant and model from the data badge: B1LA, B1LB or B1LD
- Check the pump designation on the existing unit matches VIUP15-30 CIL2
- Verify the part number 7834766 against the appliance documentation or parts list
- Check whether seals, gaskets or electrical connections are required separately, as they are not confirmed as part of this item
