Low NOx ready

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.
