Low NOx Emissions
What is
low NOx?
The Sapphire boiler produces very low NOx emissions.
NOx is the generic term for the highly poisonous nitrogen oxide gases that are produced during the combustion process.
These gases can be extremely harmful to both humans and the environment, so the Government has put legislation and plans in place to limit how much is produced.
Why are we talking about nox?
To be classed as low NOx an oil burning appliance must produce less than 120mg of NOx emissions per kWh. Blue flame boilers are able to achieve these levels by using a special high pressure diffuser plate and a recirculating blast tube. Not only does this achieve a blue flame reaction, it also produces far fewer NOx & CO gases and very low soot production.
The Sapphire boiler easily surpasses these requirements.
It is only in the last few years that NOx has become a big issue in the UK heating industry as previously the focus was mainly on reducing harmful CO2 emissions.
New requirements on flue gas emissions came into force in September 2018 that stated NOx emissions from oil boilers must not exceed 120mg/kWh. This is covered by the Energy Related Products (ErP) Directive which was enforced by the European Commission in 2015.
The domestic liquid fuel heating market is going to change dramatically over the next few years.
EOGB believes the liquid fuel industry still has a positive future, hence the significant investment to produce the next generation of liquid fuel boilers that will ensure the industry continues to provide heat for many more years to come.
The introduction of HVO fuel provides comfort to customers who want to keep their current oil supply installations, whilst still reducing their carbon.
