Navien’s blue flame technology – What installers need to know

With sustainability at the forefront of the heating market, Navien is utilising the latest blue flame technology in its range of LCB700 oil boilers for optimum levels of energy efficiency.

The company’s modulating blue flame burners guarantee superior efficiency and ultra-low NOx emissions (57mg/kWh). Navien recognises the importance of blue flame so much, it only manufactures boilers utilising this technology.

Blue flame technology has been specifically engineered to turn heating oil into a vaporised spray. This is then premixed with the air required for combustion, before being drawn in through the burner, resulting in a clean blue flame, which has much lower NOx emissions and running costs when compared to traditional, yellow flamed models. This enables installers to provide their customers with a more sustainable and efficient oil boiler when they are seeking a like-for-like replacement.

Navien has successfully developed its blue flame technology by investing significantly in its state-of-the-art facility in Seotan, Korea – the world’s largest boiler manufacturing plant, with annual capacity of 2 million units. Utilising the latest research and development, along with latest high-tech manufacturing methods, ensures every boiler is of unrivalled quality, unbeatable performance and has superb reliability over its lifetime.

Before leaving the Navien factory, every boiler undergoes a thorough, two-stage testing procedure. A specialised robotised process carries out 55 quality checks per second, prior to each unit receiving a full working test by an operative, who completes a further 250 quality checks, ensuring every boiler is of the highest standard. This is underpinned by every LCB700 boiler being supplied with a 10-year warranty as standard.

Commenting on the sustainability credentials of the range, Jason Davies, National Business Manager at Navien, said: “By utilising the latest in modulating blue flame burner technology, we’ve ensured our LCB700 benefits from the highest standards of energy efficiency. Blue flame burners are the future of oil heating, so should be considered as the ‘go to’ option, as opposed to inefficient yellow flame products. It does actually lead to the question as to why other manufacturers continue to offer yellow flame versions, considering the obvious benefits of the latest blue flame oil boilers, such as Navien’s very own LCB700 range.”

LCB700 Blue Flame boilers are also lightweight (with lift weights starting from 58kg) and “OpenTherm” ready, allowing instant access to the latest control technology, at minimum disruption to homeowners, while reducing installation costs. As a result, using Navien’s oil boilers in conjunction with the company’s Smart Plus control pack provides an overall, industry leading A+ ErP energy rating.
