Vortex Pro: External Combi
The Grant Vortex Pro range has some of the highest energy efficiency ratings in the UK which not only significantly lowers fuel bills but also considerably reduces greenhouse gas emissions and lessens the environmental impact of domestic hot water and heating systems. They incorporate the latest Riello low NOx burner technology with Grant’s patented heat exchangers to give an award winning range that meets the 2018 low NOx emission targets.
a Heating b WaterFeatures & benefits
The intelligent Vortex Pro Combi incorporates the latest Riello RDB low NOx burner technology and combines it with our award winning Vortex stainless steel heat exchanger.
The Grant Vortex Pro Combi features large heat exchangers which, due to their low water content and larger surface area, vastly increased the hot water performance. With a low system pressure cut off switch, the combi protects itself in the unlikely event of system water loss.

Low NOx ready
On 26th September 2018, the next phase of the EU’s Energy-related Products Directive will come into effect. New legislation will set maximum nitrogen oxides (NOx) emission levels that space heaters will need to meet, reducing the overall NOx emissions produced from heating. For oil-fired boilers, the NOx emissions target will be a maximum of 120mg/kWh so all oil boilers placed on the market by the manufacturer on or after 26th September will need to be compliant.
One of the overarching objectives of the new legislation is to help improve the air quality by reducing pollution. In response to both Government regulations and a growing demand from homeowners, manufacturers have continuously explored ways to make their products more efficient and sustainable. The good news is that advances with burner technology coupled to Grant’s efficient boiler designs have enabled all of our Vortex Pro and Eco boiler ranges to achieve these new targets with virtually no visible change to the existing line up.
