The intelligent VortexBlue Combi incorporates the latest Riello RDB BLU burner technology and combines it with our award-winning Vortex stainless steel heat exchanger.
The external range features a high quality, external powder-coated casing and built-in frost protection designed for all weather conditions
The Grant VortexBlue Combi features large heat exchangers which, due to their low water content and larger surface area, vastly increased the hot water performance.
a Heating b WaterAs 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.
