Grant Turbulators 476Mm Vortex Pro 46-70Kw Vbs03

Vortex Pro 46-70kw Turbulators 476mm

Grant Turbulators 476mm – VBS03

Genuine Turbulator Set for Grant Vortex Pro 46–70kW Oil Boilers

Improve your boiler’s efficiency and combustion performance with the Grant Turbulators 476mm – VBS03. Designed specifically for Grant Vortex Pro 46–70kW models, these genuine replacement turbulators enhance heat transfer by increasing resistance and turbulence in the flue gas path. This slows down exhaust flow, maximising the transfer of heat to the boiler water and reducing flue losses.

Ideal for routine maintenance or replacement of corroded or damaged parts, the VBS03 turbulator set ensures your boiler continues to operate at peak efficiency and remains compliant with Grant’s manufacturer specifications.

 Key Features & Benefits

• Genuine Grant Part – VBS03
  Engineered to Grant's specifications for seamless integration with compatible Vortex Pro models.

• Precision Length – 476mm
  Sized specifically for Grant Vortex Pro 46–70kW models to ensure correct flue gas flow dynamics.

• Maximises Heat Transfer Efficiency
  Increases surface contact between hot flue gases and heat exchanger walls for improved thermal performance.

• Improves Boiler Efficiency
  Slows flue gas velocity to allow more heat to be absorbed by the water jacket—reducing energy consumption.

• Durable Stainless Steel Construction
  Resistant to corrosion and high temperatures, ensuring long-lasting reliability.

• Straightforward to Replace
  Can be installed easily during a service, reducing boiler downtime and extending system life.

 When Should You Replace Turbulators?

Replace your boiler’s turbulators if:

• They are missing, rusted, or collapsed

• You’re performing a major annual service or desooting

• The boiler is experiencing reduced efficiency or high flue temperature

• There is excessive soot build-up or poor combustion results

Worn or missing turbulators can significantly reduce efficiency and affect emissions—replacement is essential for performance and compliance.
