Product Focus: Navien’s stainless steel heat exchangers

Navien’s range of LCB700 Blue Flame oil boilers with its blue flame technology and can achieve efficiencies of up to 104%.

One of the key components to achieving these levels of performance is a high-grade, 100% stainless steel heat exchanger, which is resistant to corrosion and erosion, ensuring durability and longevity. As a result, every Navien LCB700 Blue Flame oil boiler is supplied with a 10-year warranty as standard.

The high-grade 100% stainless steel heat exchanger material is lightweight, robust, and has low reaction to any contaminants present in a heating system’s water. Given the material’s capacity to cope with a wide range of pH values, it plays an integral role in helping maintain the performance of Navien’s boilers performance throughout their lifetime.

Endorsing the benefits of the company’s heat exchangers, Sean Keleher, National Technical Manager at Navien, said:

“We only use 100% stainless steel, as it offers fantastic resistance to corrosion. Engineers will know any fouling on the surface area will significantly reduce the heat transfer characteristics, which is a significant disadvantage when a boiler is required to operate at a high flow rate; however, stainless steel heat exchangers operate effectively whatever the velocity of the system water. Allowing water to pass through at a higher flow rate means it heats up quicker, minimising the risk of any blockages forming inside due to debris or rust.”

Due to their high levels of durability and efficiency, Navien’s heat exchangers require less preventative maintenance than their mild steel counterparts. The company’s heat exchangers are also easy to service, with the insides easily cleaned by a quick, simple brush and hoover, while they can also be flushed through with some water.

Navien’s LCB700 oil boilers also utilise the latest blue flame burner technology to guarantee the highest standards of performance and energy efficiency. The range benefits from ultralight lift weights from 58kg, making units easy to handle, while ensuring they are optimised for simple, fast and cost-effective installation.
