Feeling blue

In 2016, we saw the Energy-related Products (ErP) Directive come into force which set minimum requirements for domestic and commercial heating products. Requirements included all products clearly displaying an energy rating label (from G to A++) and boilers up to 400kW meeting new efficiency levels.

The directive was part of an EU objective to phase out low efficiency products, reduce carbon emissions and tackle climate change by 2020.

Upcoming changes

The next phase of the directive comes in to force in September 2018 and will have a bigger impact on the market as it focuses on reducing nitrogen oxide (NOx) emissions. The aim is to make sure that only the most energy-efficient, low NOx heating products are manufactured and installed across Europe.

As part of this, the demand for the low NOx boilers is increasing and forward-thinking manufacturers such as EOGB have spent years developing new and innovative blue flame products to satisfy the new tighter standards set by the directive.

What is blue flame technology?

Heating products which use cutting-edge blue flame technology produce a clean burning flame which has soot-free combustion, significantly reduces the amount of heating oil used and cuts down the NOx emissions produced.

It works by heating oil becoming atomised at high pressure before being mixed with pre-warmed air and ignited. Hot combustion gases are then re-circulated through the burner blast tube via a specially designed slot which produces a blue flame.


EOGB’s blue flame burner is due to be launched to the market later this year. As well as meeting the new targets which come into place in 2018, it also meets even lower 2022 requirements well ahead of time.

Unlike other low NOx products currently available, EOGB’s blue flame burner is fully-modulating which delivers even further energy savings. The innovative control system means it can also operate as two-stage or on/off, or two stages for heating and a third stage for hot water demand if utilised with a combination boiler.
