What it is
The Baxi 5114779 is a wiring harness classed as a wiring part, supplied under the product name WIRING - DHW PRIORITY/ SENSOR. It is manufactured by Baxi and forms part of the electrical connections for the domestic hot water (DHW) priority sensor on compatible Baxi Megaflo and System boilers.
Before you order
- Confirm the boiler model and serial number, as several Megaflo and System ErP entries are split by serial number range (for example, Serial No. Ending AC or BC, and FROM/Before serial numbers).
- Check the GC number on the appliance rating label against the fitment list where a GC number is shown.
- Check whether the boiler is natural gas or LPG, as some models are listed in separate LPG variants.
