The Grant VortexBlue combines our proven condensing boiler technology with a revolutionary new blue flame.
Using a new state-of-the-art Riello Blue Flame compact burner alongside the familiar Vortex oil-fired boiler, this market-leading combination gives you an easy to install, reliable product with those all-important low emissions.
a HeatingThe Grant VortexBlue internal models combine our existing proven condensing boiler technology with the latest Riello RDB BLU compact burner.
The boilers feature a sleek white casing, unique control panel with neon diagnostic indicators and simplified pipework arrangement, making them the ideal choice for utility room installations.
Sealed system
Sealed system versions are also available. These include a factory fitted expansion vessel, filling loop, pressure gauge, automatic air vent, pressure relief valve and high efficiency circulating pump, enabling boilers to be installed without the need for a feed and expansion tank in the loft
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.
