Grant Turbulator Vortex Eco Wall Hung Internal Wbs01

12-21 KW 16/21 ext 250mm

Genuine Heat Exchanger Baffle for Grant Vortex Eco Wall Hung Internal Boilers

Improve your boiler’s efficiency and maintain peak heat transfer performance with the Grant Turbulator WBS01, specially designed for use in Grant Vortex Eco Wall Hung Internal models. This genuine Grant part fits into the flueway of the heat exchanger, disrupting the flow of flue gases to increase turbulence, slow exhaust velocity, and maximize heat absorption into the boiler water.

Whether you're carrying out a service or replacing a damaged or missing turbulator, the WBS01 helps to maintain the high-efficiency operation expected of modern condensing boilers.

• Heat-Resistant, Durable Construction
  Built from robust materials capable of withstanding high combustion temperatures and corrosion.

• Essential for Clean Combustion & Lower Emissions
  Helps maintain optimal burner operation and reduces flue gas temperature and emissions.

• Straightforward Replacement
  Can be fitted quickly during routine service or desooting, with minimal disruption.

Compatible Grant Boiler Models

The WBS01 Turbulator is specifically designed for:

• Grant Vortex Eco Wall Hung Internal 12–21kW

• Grant Vortex Eco Wall Hung Internal 16–26kW

• May also suit other compact Grant wall-hung condensing oil boilers—check your boiler’s manual or part list.

If you're unsure about compatibility, contact our expert team with your boiler's serial number—we’ll help you identify the correct turbulator model.

When to Replace a Turbulator

Replace your turbulator if:

• It’s missing, bent, rusted, or degraded

• You notice reduced boiler efficiency or increased flue temperatures

• You're performing an annual boiler service or full clean

• There is visible soot build-up or incomplete combustion signs

Damaged or missing turbulators can lead to performance loss and higher energy costs—regular checks and timely replacement are essential.
