A Grant VortexBlue proves to be the ideal boiler replacement for a property in Berkshire

Case Study

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.

From 26th September 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.
