Frequently Asked Questions

Is the Viessmann 7824207 compatible with Vitodens 100 boilers?

Yes. It is confirmed for the listed Viessmann Vitodens 100 WB1A heat-only boilers and selected 100-W WB1B heat-only and compact models.

Does this flow switch fit the Viessmann 100-W WB1B 26kW Heat Only?

Yes. The Viessmann 100-W WB1B 26kW Heat Only with GC No. 41-819-24 is included in the confirmed compatibility list.

How can I confirm that Viessmann 7824207 is the correct replacement?

Check the part number on the existing component and compare the complete boiler model, GC number and serial number with the compatibility information above. A Gas Safe registered engineer or boiler-parts specialist can assist where the original number is unclear.

What symptoms may indicate a flow-switch problem?

Possible symptoms may include the boiler failing to recognise water flow, intermittent operation or the appliance not completing its normal operating sequence. These symptoms do not confirm that the flow switch is defective, so professional testing is recommended.
