What it is
The Baxi 7661748 is a heat exchanger assembly, classed as a heat exchanger part, for Baxi gas boilers. The heat exchanger transfers heat from the burner combustion gases to the water circulating through the boiler, supplying both central heating and hot water depending on the appliance.
Before you order
- Check the boiler model, serial number ending and GC number against the appliance data plate, as fitment varies between serial number ranges.
- Confirm whether the boiler runs on natural gas or LPG, as some models have separate variants.
- Note the GC number on the appliance rating label to match against the fit list above.
