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 the 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. The features include:

Award winning Vortex condensing heat exchanger

90.7- 93.3% Gross SAP2009 annual efficiency

Outputs ranging from 15-36kW

Market-leading Riello Blue Flame burner

Familiar burner technology

Exceptionally quiet when in operation

Sleek white casing

Neon diagnostic indicators

Designs like the ‘Multi Pass’ boiler achieved efficiency levels far in excess of any UK or European Standards and have helped thousands of homes to reduce their annual fuel bills. Grant Vortex and VortexBlue oil-fired condensing boiler ranges with exceptional SAP2009 efficiencies up to 93.3% gross (97% gross for SAP2005).

Grant’s ultra-high efficiency condensing oil boilers have been on the market for over 10 years and features 60 different model variations, with outputs ranging from 12-70kW.
