Vortex Blue: External
Grant VortexBlue Blue Flame boilers incorporate the very latest low NOx Riello oil burner technology.
This means that the Grant VortexBlue boilers not only meet current NOx emissions targets but are future proofed against any future stringent low NOx emissions targets. The external range features a high quality, external powder-coated casing and built-in frost protection designed for all weather conditions.
a HeatingFeatures & benefits
- *10-year guarantee when installed by a G1 accredited installer (T&C’s apply)
- Award winning range
- Available in outputs of 15-21kW, 21-26kW and 26-36kW to suit a range of properties.
- 90.7- 93.3% Gross SAP2009 annual efficiency making the range one of the most efficient boilers on the market.
- Factory-fitted multi-directional flue, saving time and money.
- Main isolating switch and a test switch
- 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.
- Grant VortexBlue external modules can be converted to sealed system operation by purchasing a pre-assembled kit from Grant UK. This includes an expansion vessel (size varies), automatic air vent, pressure relief valve and circulating pump. A filling loop and pressure gauge are also supplied as part of the kit. These can be fitted within the module casing, or ideally in a convenient site within the building, located between the cold main and central heating return.
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.
