Grant Bottom Baffle – WBS03A

Genuine Replacement Bottom Baffle for Grant Vortex Eco 12/16kW & 16/21kW Boilers

The Grant WBS03A Bottom Baffle is a genuine replacement baffle designed specifically for the lower section of the heat exchanger in Grant Vortex Eco 12/16kW and 16/21kW oil boilers. This component plays a vital role in increasing boiler efficiency by slowing flue gas flow and enhancing heat transfer within the combustion chamber.

Made from high-temperature-resistant materials, the WBS03A helps maintain optimal burner performance, reduce fuel consumption, and support clean combustion. It’s an essential part to inspect and replace during routine maintenance or boiler servicing.

 Key Features & Benefits
