Features & benefits

  • Neon diagnostic indicators making fault diagnostics easier
  • Award winning range
  • Available in outputs of 21, 26 and 36kW to suit a range of properties.
  • 89.5- 91.6% Gross SAP2009 annual efficiency
  • The Grant VortexBlue Combi features large heat exchangers which, due to their low water content and larger surface area, vastly increases the hot water performance.
  • With a low system pressure cut off switch, the combi protects itself in the unlikely event of system water loss.
  • The boiler features two very accurate electronic temperature controls which allow the boiler to operate in condensing mode on central heating whilst maintaining its instant hot water production.
  • Uses the market leading Riello Blue Flame burner which as the name suggests produces a blue flame, rather than the usual yellow colour of the standard burners fitted in our current Grant Vortex range. This results in a much cleaner combustion process and added benefit of producing extremely low NOx emissions.

Blue Flame Technology

Blue Flame Technology

Grant and Riello’s R&D have together successfully matched and field trialled this new range of innovative appliances. 

As the name suggests, the flame produced is blue in colour, rather than the usual yellow colour of the standard burners fitted in our current Grant Vortex range, which results in a much cleaner combustion process. All of the Grant VortexBlue boilers operate at the very high efficiency levels expected of the Grant Vortex condensing range and have the added benefit of producing extremely low NOx emissions.

In 2018, oil fired boilers installed in the UK will have to meet lower NOx emission targets. Furthermore, it is likely that even more stringent emission levels will be set in future years, so Grant have taken the decision to try and future proof oil fired appliances by moving to very low NOx, Blue Flame technology today.
